Houston-based Nonya Grenader teaches at Rice University and is principal of her own small firm. Her three most recent architectural projects received design awards from the American Institute of Architects; we especially admire her brilliant RBW Core House, a reinterpretation of the shotgun-style structures typical of Houston's Third Ward. Grenader (working with Danny Samuels) inserted a new core (containing bath, kitchen, and mechanical elements) in an existing 500-square-foot house. The house will be used for visiting artists in residence.
