Somerset House embraces its steep hillside setting, transforming it into a seamless expression of California’s indoor–outdoor lifestyle. At its heart, an open-air living room rests beneath the broad canopy of a majestic coast live oak, with delicate tree ferns softening the edges in lacy green. The home’s once-traditional brick paving and walls have given way to sleek buff concrete pavers and a bold, black-painted wood fence—a modern frame that highlights the architecture. The slope beyond bursts with sculptural agave and striking succulents, their vivid foliage offering year-round color without dependence on blooms. Inspired by the artistry of a patchwork quilt, the landscape weaves texture, form, and color into a composition that is both contemporary and timeless.
