I live in a single-family detached condo, one of several on a very small lot. Each unit has a very small (400 sqft) attached yard, and each unit is about 10 feet from it's neighbor. It's a type of urban infill development. A long time ago the whole lot was occupied by a gas station. It does a great job of providing us the "single family" feel while also achieving higher density.
