app.sketchup.com is the AMAZING web app version of SketchUp. In the 3D Warehouse, there are millions of homes & buildings already made. You can download all for FREE and then easily take them apart & make them unique. NOTE! When you first get to the 3D Warehouse area, you'll default be in & searching the "Products" area, this is just for official Products that manufacturers have uploaded (super cool!) but you must click "Models" button/area right next to that, this is where billions of models uploaded by random people are found & 99% of the time the only place to search. Some Models are insanely detailed. Keep searching different words to find what you want, search here is picky. Good Luck!
