A high level of custom detail is signature to the rooftop design for this 80-unit affordable housing project, which provides daycare. Custom elements for the children include a cast-in-place concrete sandbox, raised concrete planters that double as child-height seating, and a curved, translucent fence whose surface can be painted on by the children and then washed. Courtyards are also enlivened by hand-hewn, reclaimed cypress benches and concrete planters filled with bamboo, designed in the shape of bamboo leaves.
