A singular luxury architectural estate, "Horizon House," designed in collaboration with Griffin Enright Architects, crowns the apex of a quiet hillside street with sweeping city, canyon, and valley views. Conceived as a work of art, this single-story, three-bedroom residence is organized around light, volume, and form. Soaring ceilings become a fifth surface, animated by a sculptural clerestory of east-, north-, and west-facing windows that gathers changing daylight from morning through evening, casting an ever-evolving, cinematic glow throughout. Expansive walls of custom glass and signature peel-out windows dissolve the boundary between indoors and out, framing uninterrupted vistas at every turn. The principal living spaces flow effortlessly to a private pool, expansive deck, and outdoor entertaining areas, creating an immersive expression of Southern California indoor-outdoor living. An extended roofline provides shade and sculptural presence while strengthening the connection between the architecture and its hillside setting. Set on a rare, wide street with underground utilities and clear sightlines, this fully permitted residence reflects a level of design, engineering, and craftsmanship rarely achievable today -- offering an architectural living experience that is both deeply considered and exceptionally difficult to reproduce.

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
