A rare convergence of scale, pedigree, and setting, Hayfield House is a landmark Julia Morgan designed estate distinguished by its extraordinary grounds, privacy, and enduring presence on the San Francisco Peninsula. Commissioned in 1919 by Mr. and Mrs. Chauncey Goodrich, the ~12,500 sqft residence is Morgans elegant interpretation of an English country estate, thoughtfully designed to embrace its remarkable setting. Beyond double gates and along a long private driveway, the ~4.86 acre estate unfolds with an exceptional sense of seclusion and tranquility. Expansive porches open to beautifully manicured grounds, sweeping lawns, magnificent gardens, and a serene pool. Tennis and Pickle ball courts, framed by vineyards, create an idyllic setting for a match. Inside, the interiors showcase unparalleled attention to detail, with grand rooms, soaring ceilings, intricate crown molding, artistic chandeliers, and bespoke stonework. Despite its impressive scale, the home possesses an unexpected sense of comfort and intimacy, equally suited to peaceful, quiet days and sophisticated entertaining. A stunning ~1,500 sqft guest house complements the main residence, while a detached four-car garage provides additional convenience. Hayfield House is truly a "World-Class" estate!
