I just don't have room for houses on my O-gauge layout. I may built a model of my current houses just to puyt on a shelf, though, it would be a fun project.
When I had an N gauge layout I had a subdivision of 47 homes: every house that I, my grandparents, parents, uncles, aunts, and my three boys have lived in, including present houses. It was a lot of fun to model. Here is a photo of one set of four I kept when I tore down the layout to go to O. I had set up the Faller car system on the subdivision and had a tiny garbage truck that would go up and down the streets stopping every so often. If was fun to watch.
