At street level, drifts of feather grass and a gnarled olive tree give this South Bay home a front yard that feels native to the coast, unhurried and quietly beautiful. The planting does the work without asking for attention. Up above, the rooftop tells a different story. A full renovation transformed the space into an open air retreat, with a spa, fire feature, and generous seating arranged around a sculptural spiral staircase. Surrounded by neighboring rooftops and open sky, it is the kind of space that makes you forget you are in the middle of a neighborhood.
