Design a Building
Choose a style and what the building must hold, and a house, a country house, a palace, a church or a public building is designed for you in 3D by the rules of the style: its front, its rooms and its furniture, every decision traced to the treatise or the building it comes from. Change the walls, doors and furniture on the plan, walk through the rooms, and save or share the design.
The styles: Tudor, Victorian, Edwardian, American Colonial and Craftsman houses; and Greek, Roman, Renaissance, Palladian, Baroque, Neoclassical and Georgian buildings. Read their rules in The Textbook of Architecture: the styles of architecture, the Atlas of Rules.
