Residential22nd Lower

This pristine modern duplex steps down its steep site, clad in a sustainable, durable material palette of Ipe, stucco and galvanized sheet metal to articulate and give scale to the exterior. The building maximizes its corner location with sidewalk-oriented plantings for greening and 180-degree views from all levels.

The energy-efficient units feature photovoltaic panels and radiant heating. Custom elements include a steel stair with recycled bamboo treads, metal and glass shelving, and caesarstone and slate counters.
