Set on a flat corner lot in one of Atherton's most scenic blocks, this majestic Mediterranean estate sits on 1.12 acres surrounded by mature trees and luxury resort-style landscaping. Designed by John Stewart, the home's prized layout is practical yet impressive with soaring ceilings to bring in natural light, thoughtful indoor/outdoor integration, and a seamless flow between all living areas to create a harmonious lifestyle. Sophisticated architectural details will impress you upon arrival, including tall columns at the entry and a striking two-story foyer with marble and travertine floors. The living level is spacious and commands attention, with a gorgeous wood paneled library, stately formal living and dining rooms, and marble wood burning fireplaces grounding each area. Upstairs, four ensuite bedrooms gather in a private wing anchored by a primary suite with his & hers walk-in closets and a sauna. Both levels have their own dedicated laundry rooms for easy daily use. A fifth bedroom sits on the main-level for in-laws or an au-pair.
