The design for these houses was taken from an exploded diagram in the glossy book which accompanied the Architecture Studio (21050) set. I build two, mirror images of each other, as a prototype for future houses in my Micropolis layout. I think they worked out quite well.
After a bit of fiddling about, I realised that I could get four of these onto a baseplate, with a little gap around each one. Take a look at the Virtual Micropolis: Four Square module.
