I built a trio of small houses (16×16 stud footprint) as practice in building in different architectural styles with LEGO. There is a Victorian with bay window, a house with a dormer window in the roof, and a steeply-roofed house.
They’re all a bit too small to be realistic, even by LEGO standards, so I am planning to scrap them and try to build some new houses on a 32×32 footprint. Stay tuned.
Update 30-May-2007: Photos and LDraw instructions are now available on Brickshelf.
