One of my readers was asking me for a freeware interior design application which would be helpful for him to decorate his new house. I suggested him to take a look at Sweet Home 3D. Sweet Home 3D is a freeware software which will help you to place your furniture on a house 2D plan, with a 3D preview. Sweet Home 3D will definitely help you to design your interiors very quickly. You can easily draw the walls, change the textures of the walls, drag and drop the furniture in the plan in a 3D view.
So before buying new furniture and arranging them in your house you can actually use the 3D models, arrange them and feel the new look with the help of Sweet Home 3D. You can also import additional 3D models created by others(BJ, LWS & 3DS formats), change the size, orientation and elevation of each piece of furniture in a 3D view. Sweet Home 3D provides you good number of objects to place them in your house. You can even set different furniture attributes like Name, Height, Width, Depth, Elevation, Color, Angle, Abscissa, Ordinate, Movable, Door/Window and Visible. The simple interface will attract a lot of users. But Sweet Home 3D cannot be a replacement for professional 3D modeling applications.
Sweet Home 3D runs on Windows, Mac OS X 10.4 / 10.5, Linux and Solaris with Java installed on it.
