An infill lot is a vacant or underutilized parcel sitting within an already-developed urban or suburban area. Building on these sites adds housing where infrastructure already exists, without sprawl, without long commutes, and without sacrificing the character of the surrounding neighborhood.

The challenge is that infill lots are rarely cookie-cutter. They're narrow, irregular, steeply sloped, or oddly shaped. Standard plan books don't work. Our plans do.
