This low-slung sorta Usonian-style home mounted between the Sugar Creek and Riverbend country clubs in Sugar Land was built in 1975 by and for Houston builder H.A. Lott, known for his work constructing the Astrodome, among many other local buildings. The home was designed by local Frank Lloyd Wright devotee Karl Kamrath of MacKie and Kamrath Architects. After a few recent updates of the granite countertop, mosaic tile, and vessel-sink variety, it went on the market last month — for $1,080,000.
