There were a couple of lots that I spent a lot of time dreaming up a house for before we were really in a position to buy one. These are some sketches of a couple of designs I was playing around with.
This was on a tiny lot zoned RMF-45 (warning: boring zoning link!), which allowed for a lot of height.
This was on a tiny lot that was triangular (all the lots are going to be tiny).
