The closer-in you go, the less space you have to work with, and those constraints can be tricky. But don't let the fear of a tiny lot stop you.

Over the past year, BUILDER has shined a spotlight on many successful smaller homes and urban infill projects, and discovered many tricks and tips for making the most of the least.
