Every room was built to show off the hillside
This brand-new custom home pairs high-quality craftsmanship with sophisticated finishes, soaring ceilings, and an open-concept design. Expansive windows frame panoramic city-light and rolling-hill views from the main living spaces, while the family room gathers around a fireplace beneath a double-height volume of light.
The main level includes a private ensuite bedroom and a powder room, ideal for guests or multigenerational living. Upstairs, the primary suite opens to a spa-style bath with a freestanding soaking tub, a walk-in shower, and an oversized walk-in closet, and two additional bedroom suites join a versatile loft made for an office or study.

The Gourmet Kitchen
