This was done in a 10th grade geometry class with 8 students. There was a 5 week deadline that begun with students designing 2D floor plans and land plots. The land plot must be between 2,000 and 10,000 square feet and the house had to be between 1,000 and 5,000 square feet. They were encouraged to make realistic homes that someone could live in even though a couple are questionable :)
Students worked on the computers once a week, but much of the work had to be done on their own. They needed to use layers and scenes to deal with a lot of objects, and they were required to make windows and doors to a real scale. We prepared for the project by copying some blueprints and making standard houses before they had to make their own.
I have done an architecture project every year, but this is the first year doing it on SketchUp.
I especially like the round kitchen (though it may be a little hard to find appliances for it). I'm also impressed by the changing styles, use of shadows, and presentations of both exterior and interior views. Beautiful job by the students, and congratulations to Willy for coming up with this neat project!
Anyone can design anything in 3D! http://www.3dvinci.net/
