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.
