This contemporary home is one of two custom designs deemed the Twin Houses by architects Predock-Frane in the coveted Pacific Palisades' Marquez Knolls. The structure combines two classic California typologies: hillside home and courtyard house. The three story structure's sophisticated massing reflects the site's sloping grade with split levels connected by sculptural stairs and a two story atrium connecting the bottom two levels with the home's central courtyard. The subtly angular home's stained wood siding not only provides a cohesive exterior surface, but a 'rainscreen' system that also acts as a passive solar system, improving the home's thermal performance in warm and cool seasons. To enter, one descends into a void-like entry vestibule that culminates in a glass partition, which gives the first preview of the voluminous social spaces. On the entry level is an en suite office (which could be a fourth bedroom) and powder room. Down a series of steps is the open living space, where a sculptural ceiling connects the living, dining, and kitchen area. Fleetwood doors open this space to the central lounging courtyard and verdant property beyond. A towering, yet diaphanous bamboo grove on the downsloping south-side of the property provides privacy, green views, and dappled light into these spaces. Upstairs, the primary suite flows from the bedroom up to the sitting area to the sea-view deck to the cleverly-designed marble and frosted glass primary bathroom. An entire wall of integrated wood closets connect the spaces. On the lower level of the home, a comfortable den rests
