The work of designers and planners is greatly simplified by the availability of software that allows you to develop designs for residential buildings. Expensive and rather complex programs for designing a house, which are not always clear to novice designers, have gained great fame. Quite worthy competition for such software is created by simpler, and most importantly, free programs for designing houses and developing individual structures.
Some of the most popular home design programs are:
Advantage Features
Free programs for building and designing houses have a number of undeniable advantages in comparison with expensive branded software. First of all, it is the availability of programs within the network and the possibility of free download. For those who are just starting to master the expanses of design, the following advantages can be distinguished:
- Simplicity of the interface with the maximum possible set of necessary functions and tools;
- A small amount of space on the disk space of the computer;
- Ability to create volumetric images and 3D models.
Functionality
In terms of a set of options and tools, they are practically not inferior to professional software. Among the free offers, this is the most convenient program for designing frame houses, which is popular today. It should be noted that on the basis of projects created with its help, buildings in the private sector are often erected, as well as country houses in rural areas. Downloading a program for designing houses is also recommended for those who have planned to build their own. It is customary to single out 3D programs for designing a house in a separate category. Working with novice users with them is somewhat difficult. But this is true for professional programs.
The construction of any house begins with the development and creation of project documentation. An integral part of the package of documents, even if you are going to build it yourself, are drawings and working diagrams. Whatman paper, pencil and ruler are already in the past, today a program for creating drawings is used instead.
Creating a drawing of a house in a special program
Quickly, simply and conveniently, and most importantly, gross errors and miscalculations that computer programs do not allow or eliminate automatically are minimized.
To date, there are paid and free programs that allow you to design in two- and three-dimensional space. This is very convenient, since, in addition to a strict drawing, the user can see a realistic live model at any stage of work.
The program can be downloaded for free from the official website. It has a simple interface and rich features. This program belongs to the multifunctional semi-professional packages that offer a huge number of opportunities for individual builders and small entrepreneurs. Often it is used in their work by professional designers and developers.
This is how the Google SketchUp interface looks like
In this program you can:
- Make a simple drawing;
- Come up with a detailed;
- , cottage or backyard building;
- Choose the design of the facade of the house;
- Perform landscaping and.
Working with two-dimensional images is not all that Google SketchUp can do. In addition, it is still very simple and convenient. That is, all the projects you have created can be viewed in three-dimensional space on the screen.
One minus - you can create drawings, but you won't be able to use them as official documentation, only as instructions for your own use. Unfortunately, it does not support GOSTs and SNIP.
Pluses are the high realism of the created images, the Russian-language interface, numerous manuals, instructions, blogs, communities, thematic groups, video tutorials and other communities that seriously help in mastering the program.
Ready house project created in Google SketchUp
In addition to two-dimensional graphics, there is access to three-dimensional models of the created drawings at any stage of their readiness. A huge number of libraries, applications, add-ons and settings turn AutoCad into a professional tool for engineers and architects.
Cottage interior created in AutodeskAutoCad
It is unlikely that users without specialized education will be able to figure it out on the fly, even numerous lessons presented in text and video versions will not be a serious help.
Compass
A program in Russian, which was created to build drawings and three-dimensional models. It includes several main areas:
- mechanical engineering;
- construction;
- instrumentation.

Programs for designing landscape design
It is the "Construction" block that is suitable for solving everyday problems, creating models and drawings of the future home. 
The advantage of the program is that it automatically performs cuts and sections of the created model, eliminating possible designer errors. Can be used to prepare a complete set of project documentation.
Compass Construction includes all the necessary set of applications to design a building on a turnkey basis. Starting from the creation of a 3D model, with a detailed study of the appearance, facade and other things, and ending with all engineering communications: water supply, sewerage, electrical networks, heating, and so on.
T-Flex Cad
The program has a free version and is designed to work with both two-dimensional and three-dimensional images. It has a wide range of features and a comprehensive set of functions for drawing diagrams and . You can create both separate elements and the whole building with a section of all facades and floors. The developers of T-Flex Cad have made an emphasis on the automation of all processes. Designing is carried out quickly enough, accurately and with a minimum number of possible errors. Creating parametric models is the best use for the program.
With this utility, you can both develop all the necessary documentation for the construction of a private house, and use it to develop unique pieces of furniture for the future interior.
T-Flex Cad provides full support for ESKD and foreign standards.
Creating an apartment layout in T-Flex Cad
Model elements are interconnected by parametric and geometric relationships. The benefits of the program include:
- Powerful geometric core;
- Ease of working with assemblies of any complexity;
- Single file format;
- Advanced engineering analysis tools;
- Ability to create your own libraries of elements;
- Teamwork on projects;
- Integration;
- Automation;
- Preparation of drawings in accordance with standards.
These features of T-Flex Cad make it a worthy competitor, but much simpler and more understandable.
ARCHICAD has flexible import settings: all elements provided in the program have the properties of the IFC standard. If subcontractors need to calculate structures, for example, in LIRA-SAPR, you will only need to set up an IFC-scheme. Previously, for this, the model was transferred according to 2D drawings and spent at least two weeks on this.
Bonuses:
1. Convenient functionality for creating an explosion diagram using the "3D section" and "3D document" tools:
2. training video tutorials on the official YouTube channel of the developer "GRAPHISOFT Russia" (from these videos I started learning ARCHICAD), here you can also learn a lot of knowledge about design from leading Russian bureaus. 
We cut our great project through a 3D section, apply the "axonometric projection view" - because it's fashionable. We create a 3D document, set up pens and graphic replacement, put the saved view on the sheet. Repeat as many times as there are floors. Ready. Your explosion diagram is ready, you are amazing!
Cinema 4D, twinmotion, Lumion, Artlantis
All developers provide a free educational version.
Application: project visualization.
The best applications for visualization of the ARCHICAD model. Twinmotion, Artlantis, Lumion are the most intuitive: they are suitable for quick learning and allow you to get an acceptable result with minimal effort. 
Since the 18th version of ARCHICAD, I have been using third-party renderers less and less, since rendering can now be done internally by CineRender. I advise you to watch the YouTube channel of Svetlana Gaios - there is a lot of useful information about visualization in ARCHICAD.
Bonuses:
- export of ARCHICAD models in the Artlantis file format does not require reconfiguration, because it is carried out using an extension that can transfer geometry, textures, perspective cameras, lights, sun and layers;
- the same extension gives an amazing opportunity to update the second Artlantis file, transferring the settings of the first file to it, if the model itself from ARCHICAD has been changed;
- updating the source file in Twinmotion works in the same way;
- In the new version of Lumion, thanks to the LiveSync plug-in for ARCHICAD, you can customize the rendering of the model in real time (see the plug-in link below).
Adobe package: Photoshop, InDesign, Illustrator
Availability of free/educational version: alas, no, but there are discounts for students and teachers, the subscription is monthly. The free version is valid for a week.
Application: post-render, tablet layout. 
Visualization made in ARCHICAD. Post-processing is always in Adobe Photoshop: collage is applied here, as well as filters and color correction
Adobe Photoshop is a tool for processing raster (vector - I do not advise) photos. To “hold out” the render, make color correction, add people, atmospherics - we do all this here.
Adobe InDesign is a layout tool for a tablet or portfolio.
Adobe Illustrator is a vector graphics tool. Useful for preparing diagrams for the project - infographics, situational diagrams.
Bonus: The Magic Pencil filter and color grading in Photoshop are my biggest helpers when it comes to brushing up a render very quickly. 
For example, to make a “almost a drawing” out of a render, it is enough to desaturate the image, apply the Outlined Edges filter, and then play with blending modes on a new layer filled with one color.
BIMx
Availability of free/educational version: BIMx is a free version of the application for demonstrating architectural projects, BIMx PRO is a version of the application with advanced functionality, messaging in BIMcloud (it is convenient to make edits), measurements in 2D and 3D. Available in the AppStore and Google Play.
Application: project demonstration. 
This is what my phone looks like when I'm showing my teachers what I'm working on, defending a project, or just explaining to my friends why they haven't seen me in over a month.
BIMx is the best tool to convey project ideas to the teacher/customer. The application allows you to view the BIM model in 3D space, provides convenient navigation through 2D documentation - and all this through a mobile device, tablet. Browser view is also available.
Possibilities:
- 3D model;
- 2D documentation;
- spectacular smooth transitions between 3D and 2D projections;
- 3D sections;
- access to cloud storage;
- element information sets;
- displaying zone information.
Bonus: show teachers the project on a tablet or with the help of VR-glasses and get an "A" automatically!
BIMsight And Solibri Viewer
Availability of free/educational version: distributed free of charge.
Application: Applications for viewing IFC files. 
Architecture students need to learn how to work with IFC, be able to check the correctness of the saved IFC from ARCHICAD for subsequent calculation and design in LIRA-SAPR or TEKLA.
About *dwg
ARCHICAD has a convenient and intuitive import: just drag a *dwg drawing into the working window and you can start working! It is also worth noting the nanoCAD platform - a free CAD with support for the * .dwg format, the SPDS of which is tailored to Russian standards and regulations.
Instead of an afterword
If you've read this far, then you're really serious about architectural software! The list is by no means short. But the best of all is an integrated approach to business, and for me it is ARCHICAD. The program helps me solve everyday architectural problems and improves with me.
Computer, tablet, phone - daily interaction with them has become our ritual. And it's up to us to decide: take a million selfies, take pictures of cats, or, finally, open up new opportunities and achieve the result you dream of. Your digital future is closer than expected! Good luck and creative success! 
During the writing of the article, I could get a "black belt" for editing gifs :)
If it so happened that there is an irresistible desire to read me further, or maybe there are questions that I would like to ask, then all this can be done if you subscribe to my channel on instagram @zamotanya. There you can find posts about participation in competitions, information about current architectural events, see how projects are born, or you can just write and talk about programs or about studying at an architectural university.
Well, which of the townspeople does not dream of having a cozy place where one could hide from the hustle and bustle of the city for at least a few days?
Today, making dreams come true is not so difficult. You can find a ready-made cottage or just buy a plot of land in a picturesque place and equip it according to your own vision, buying a standard project for its development from an architect or developing one yourself. To lay out a garden, improve the yard and build original architecture and layout of housing will help programs for designing houses.
Benefits of custom design
First of all, the fact that it allows you to put a house on a site of any geodetic complexity. In addition, it will be possible to make it of any number of storeys and place as many multi-functional rooms in it as your heart desires. Do-it-yourself 3d modeling of houses is an opportunity not only to save a lot of money, but also to spend it efficiently, and start doing it literally from the first stages.
Self-designing houses to save money
Technological progress has opened up a lot of opportunities in this regard. Now, designing houses does not require specific education and drawing skills. Everyone who has a personal computer can start creating a layout of a future masterpiece. Work can be carried out both online and offline. In the latter case, you will need to download one of the program options on a PC.
Computer design of houses: advantages
Home design software is not just architectural software to help kick out the box of a house and select the design of the facade. They make it possible to visually plan the entire site, that is:
- place outbuildings and additional buildings;
- arrange the adjacent territory;
- develop an interior environment.
The program for designing houses will help you plan the entire site
The main advantages of design programs are:
1. Possibility of planning houses in great detail.
3. Financial and intellectual accessibility.
4. The ability to correct shortcomings in a timely manner.
5. Availability of 3D options that allow you to view the drawing project as a full-fledged constructed object.
The project is displayed as a complete built object.
Architecture programs are available in a wide variety and they really make it easier to design houses, however, you need to understand that even if computerized, this process can take several months, so don't expect lightning fast results. On average, 3d modeling of a house takes about three months.
Design software Autodesk Homestyler
The developer of the service is Autodesk. It is available on: iOS, Android and as a web application. Distributed for free. Has a Russian interface.
The developer company is famous for its professional 3D graphics programs, but only those who have mastered 3ds max can use them. Agree, it makes no sense to delve into all the vicissitudes of science, just to see how the room will look after a cosmetic finish or when rearranging furniture, so it makes no sense for those who are interested in architectural programs to have a simplified version of the 3D editor working in the browser - Autodesk Homestyler.
Autodesk Homestyler interface
This house design program helps to quickly visualize the layout of the object and immediately improve it by filling it with furniture and other items available in the attached library.
You can work on the box by hand, trying on different interpretations of the walls and partitions. For the convenience of work, users are invited not to struggle with 3d modeling of houses from scratch, but to use blanks of 2D plans, which will become an excellent substrate.
Finding items of interest in the design program is easy, as the library is well organized. Everything you need for finishing, construction work, decor and landscape organization is divided into separate categories of the same name. Each of them, in turn, is divided into subcategories.
All the necessary elements are highlighted in the same category
What does it look like? If you go to the "Finish" section, you can find subsections: "Kitchen", "Bedroom", "Hallway", etc., each of which contains everything necessary for the improvement of the premises. So for the kitchen there you can pick up a sink, and a countertop, and a set, and other interior elements.
Layered design
Although this design program is available for free, it supports the development of multi-level objects, so the creation of two and even three-story cottages will not be a problem. But simultaneous viewing of several tiers will not be available at once, since the web application window opens only one of the floors at a time.
What else is good about this program for designing houses is the ability to calculate the amount of material required to implement the created object. All items added to the plan are immediately displayed in the "Shopping List". And this is typical not only for objects representing the situation. The service will calculate everything: the footage of the skirting boards, the square footage of the floor coverings, and the amount of paint. The finished list will only need to be printed, and you can start asking the price.
The program for designing houses will calculate the amount of material needed
Taking a snapshot
Another useful option of the program. The graphic file is available for saving at any design stage. The saved snapshot of the page can be shared by sending it to friends or posting it on social networks. The finished project is available for export in DWG format. You can create its circular panorama.
Example of saved pictures
The specifics of working with the service
Although the proposed program for designing houses is available for use without registration, nevertheless, it is worth creating an account. This opens up access to additional benefits. Registered users will be able to save catalog objects as favorites, which will speed up access to them in the future. In addition, the architectural program will give the go-ahead to save projects to the gallery, with the possibility of continuing to work on them as you wish.
Not so long ago, 3d modeling of houses became possible not only on the web service, but also on mobile devices, however, these platforms provide for slightly different functional tasks. Here the emphasis is not on the design of the building itself, but on the development of the interior of the finished premises.
3d interior modeling is also available on mobile devices
Available for review will be the project tape available to the program, where the work of other users of the service is located. They can be commented on, saved in favorites. You can subscribe to the designers you like the most.

Planner 5D design software
One of the most popular architectural online programs specialized in the planning of urban and suburban housing. Registration is not required here. You can work with ready-made templates or design from scratch.
Planner 5D does not limit the user in the number of rooms to create and the form of their layout. Here you can work on multi-storey buildings. A wide variety of furniture and plants are offered.
Planner 5D interface
However, not all objects available in the design program are used for free. You will have to pay about $5 for a one-time access to the full database of layouts, so many users prefer to immediately purchase permanent access to the catalog, which costs $20.
The full database of program layouts is paid
Program sections
There are four of them, as in the previous version:
1. Rooms. Section of the program where the type of rooms is selected, their number and footage is determined. It is possible to change the color and structural parameters of objects.
2. Constructions. This part is responsible for designing windows, staircases, doorways in houses.
3. Interior. Assistant in the arrangement of interior items, including appliances.
4. Exterior. Contains a set of additional courtyard outbuildings and buildings.
5. The Planner 5D house design program allows you to view ready-made solutions in 3D format and save the resulting layouts in the memory of your PC.
Sections of the program for designing houses
Of the positive aspects, the speed of work should be noted. The downside of the resource is still low realism and an insufficient level of professionalism.
Designing houses in HouseCreator Online
It is also a representative of free programs for designing houses, which allows not only to develop a layout of construction, but also to calculate the approximate price of the question of its implementation. Despite the intuitive user interface, the site has a video tutorial that clearly demonstrates how to work in the application.
The program has a clear user interface
How the design program works
In order to start creating a house, you need to select:
- foundation type;
- foundation width;
- number of floors;
- wall settings.
You can find all this in the pop-up windows that appear when you enter the main page of the program.
The rest is easy to understand:
1. The "Wall" section is the choice of dimensions and location of rooms.
2. The “Opening” section presents windows and doors, helps with their placement, selection of shapes, and sizing.
3. Section "Roof" - the choice of the type and shape of the roof.
An example of a project executed in the program
This program for architecture does not have the option of 3d modeling of houses and decoration service, so it will not be possible to furnish housing and immediately evaluate the final result. This does not prevent HouseCreator Online from being popular, as it is very good from a practical point of view. The program allows you to choose building materials, adjust the thickness of walls and ceilings, calculate the cost of consumables and work.
House 3D
“The program has handy features that allow you to decorate the walls and lay the flooring”
The design program will work for free on 3d modeling of houses, layout of apartments, interior filling. This is the easiest resource to learn, ideal for those who are just trying their hand at the role of an architect.
The Dom-3D program is the easiest resource to learn
The software is not too demanding on the system capabilities of the PC, so it works great even on low-power machines, which in turn does not bother users with a forced hardware upgrade.
Of the operating systems, the house design program recognizes new editions of Windows. With the rest, at this stage, unfortunately, it is not compatible.
To make the web resource competitive, and the program's capabilities even more attractive, it expanded the catalog of furniture models. Moreover, they were allowed to diversify with additional accessories that the user can seamlessly integrate into the created interior.
The program has an extended catalog of furniture models
Another interesting addition to the design program is the presence of an integrated architectural module. It is used for full-scale visualization of the object during the construction of walls, the formation of the roof, the drawing of door and window openings, and the removal of stairs. In a ready-made layout of the house, the user will be able to design the situation.
The program has convenient functions that allow you to do wall decoration and laying flooring. A slight movement of the mouse and the objects that appear in 3D space will line up in stylish interiors.
The program will help you choose the design of walls and flooring
Archicad
A bright representative of professional programs for architecture. The utility is difficult to learn, so homemade is rarely used. And many architects prefer to avoid it because of the lack of flexibility. 3d modeling of houses here takes place right off the bat and begins immediately with work with three-dimensional images. If you need to create a wall, then the “wall” tool is taken, the doorway is “door”. The program itself will decide where and what to install.
Designing a house in ArchiCad
The most valuable thing in designing houses in Archicad is that, having correctly drawn a three-dimensional model, you can immediately see the layout of all tiers, facades and sections of the building, without resorting to additional manual drawing. Extremely convenient, so the best program for designing apartment buildings is not worth looking for.
Archicad allows you to see the layout of all floors at a glance
3ds Max
A serious service designed for professionals. To agree with the customer, the architect usually has to draw several sections of the object in order to determine the height of the ceilings, the location of rooms, windows, and other nuances. If everything satisfies the requirements, then you can move to the 3 ds Max program, where you can dive into creating a three-dimensional layout. Designing houses in this utility is attractive in that you can import existing working drawings into the program, rather than creating them first. This eliminates the generation of errors. Upon completion of 3d modeling of the house, the object is visualized, i.e. its photo image is obtained from different angles.
Visualization of interiors in 3 ds Max
Working with a house design program of this level is difficult even for specialists, as it requires certain skills and abilities, so beginners should not even try to get comfortable in its open spaces.
3ds Max requires certain skills to work
Envisioneer Express
Not too fancy design program distributed for free. The utility was created to develop three-dimensional models of buildings, but you can start creating future houses with two-dimensional planning. Drawings of walls, doors, roofs, stairs and windows will subsequently be converted into a full-fledged three-dimensional layout. Upon completion of the 3D rendering, the resulting creation can be viewed from different angles and heights by changing the view mode from photorealistic view to wireframe transparency.
In addition to the "forcing" of the box, the house design program has an interior design mode. It is also possible to correct the facade and architecture of the building by changing the choice of building materials. The project is saved in software format, but can be opened by a number of other applications from the 3D design category.
The program has an interior design mode
Google Sketch Up
The unique software offers simple solutions for 3d modeling of houses and their interiors. It has a lot of advantages that make using it as comfortable as possible.
Program interface
For greater ease of use, pre-configuration windows have been removed from the program. Now here all the geometric parameters are set exclusively by the keyboard.
Another achievement was the Push/Pull option. The original tool allows you to push any of the planes to the side in order to install additional side walls along the trajectory of its movement. Foilow Me moves the plane along a pre-drawn curve.
Google SketchUp house design software
What else is possible in this program for designing houses?
1. Prepare macros in Ruby with subsequent output from the menu. They are needed to automate repetitive actions. In the software, you can find a lot of other developments created by the user audience of the program.
2. Support a variety of plugins that help create, visualize and export objects by moving, rotating and forcing the created layouts to interact.
Installing plugins in the program
3. View layouts in section and add callouts to them in the form of drawings.
4. Support the production of house elements that can be further used in the design program an uncountable number of times, including with editing.
5. Work with layers.
Designing a house in the program
6. Prepare various sections of objects.
7. Use the library of models, materials, styles, uploading interesting solutions to the Internet or replenishing its resources with your own developments.
8. Animate transitions from section to section, adjust the position of the demonstration camera.
9. Create dynamic effects, for example, simulate the opening of a sideboard door by clicking the pointer.
The program allows you to create dynamic effects
10. Engage in the design and planning of real-life buildings and create real-life objects.
11. Indicate the dimensions of the object in meters or inches.
12. When designing houses, select graphically correct shadows that fully correspond to the given time of day, year, and correspond to the parameters of the latitude and longitude of the location of the object.
For independent design, you can spend all your free time without restrictions until you get a decent result.
To create a building and interior project yourself, it is enough to get acquainted with the general principles of the program.
It is not difficult, as the menus and basic actions are obtained on an intuitive level.
It is enough to try simple actions once, and then you can improve your skills and expand the range of options from simple to complex.

Standard operating procedure on the example of an online designer Planner 5DPlanner 5D
Design programs are designed with the international consumer in mind, so manufacturers initially prepare projects in several languages.
Most pointers are presented in the form of pictures and pictograms or are accompanied by tooltips.
To do this, pay attention to the checkbox located in the upper right corner of the screen. When you click on it, a list of possible language options appears.
The next step in designing online is to indicate your determination and click on the checkbox with the words "Create a project" and select the appropriate item from the options offered. The creators offer three options:
- Start from scratch
- Continue a started project
- Choose a ready-made template as a basis and make your own adjustments to it
Before starting work, the user is shown the features of the program, which can be viewed once, and later refuse to show them by clicking the “Do not show another time” button
You can go directly to the simulation by simply clicking on the cross in the upper right corner.
To draw a project use a menu of four items:
- Rooms
- Constructor
- Interior
- Exterior
On the first visit, a room plan is presented on the screen, which can be used for further constructions, or it is deleted and the independent design begins from scratch. To do this, become the mouse on the image, wait for 3 pop-up images to appear and select the icon with the trash can.
Be careful with this icon in the future, as it removes the image immediately without specifying whether you really want to delete everything, as is common in many office programs. If you carelessly press all the work will have to start over. If you like what you have already done, you can save the image by clicking on the corresponding button in the vertical right menu.
To draw a project of a room with a non-standard shape and size, use the mouse, with which you can quickly change the outlines of the room and give it the most non-standard look.
Such an individual project will allow you to plan in detail a loggia, balcony, pantry or other room with non-standard outlines.
3D Online home, design and interior constructor from our catalog of online services will be useful to those who plan to build a cozy house in the near future, but do not yet know how it will look, how many rooms it will have, how to arrange furniture in the house, what kind of view it will have from the windows of the future house. And in order to help decide on all these issues, an online design and interior program called Planner 5D has been created.
