How to Create a 3D Model of Your House Plans for Free


by Bryan McDonald on April 5, 2010

Sweet Home 3D is a free interior design application that creates a 3D model of your house plans.  You can upload a copy of you house plans or draw the plans yourself.  The application is easy to use and there is an online version so there is nothing to download or install.  You will need to register and login if you want to save your 3D model.

This program is aimed at people who want to design their interior quickly, whether they are moving or they just want to redesign their existing home. Numerous visual guides help you draw the plan of your home and layout furniture. You may draw the walls of your rooms upon the image of an existing plan, and then, drag and drop furniture onto the plan from a catalog organized by categories. Each change in the 2D plan is simultaneously updated in the 3D view, to show you a realistic rendering of your layout.

Sweet Home 3D is a fun an useful tool for anyone that needs help arranging the furniture in their house.  This would be especially useful for someone unsure how to arrange their furniture in a new house they are buying.  You can make very detailed 3D models that include not only doors, windows, and furniture, but also items like shampoo, tissue boxes, and iPods.

I played around with the online version today and it only took me a few minutes to learn to use it and create my first 3D model.  The image below shows the house plan I used (top window) to create the 3D model (bottom window).


Version 2.3 was released March 22, 2010 and includes new several new features like video creation.  Video creation lets the user create a virtual path in the 3D view and create a video from that path.  You can view a video that was created of a 3D model on their blog.

Sweet Home 3D has an complete user’s guide to help you.  You can also view their online gallery to see examples of what you can do.  According to their website, 212,192 people downloaded the program last year.  I can see why, it is a fun and very useful tool.

Great post. I have seen some of these programs in the past but they were done with software you had to download on your computer. Looks like it does a great job. I will have to try it out.

Thanks Tom, I am like you, I am much more likely to try out new software if there is nothing to download. The tool really did a great job of creating a 3D model. Let me know if you try it out.

I will definitely give it a go. I know it will come in handy with picky/sophisticated sellers :)

Great video, Bryan. I’ll be looking for a reason to use this at some point.
