Beautifully sited on one of San Marino's most treasured and prestigious streets, 1535 Circle Drive rises gracefully above Lacy Park as a rare and exceptional estate. Designed by noted architect Robert Sinclair and meticulously built from the ground up in 2002, skilled artisans created this timeless French Chateau-inspired residence. Cherished by the same family for over 27 years, this enchanting South-facing masterpiece is surrounded by magical gardens, bubbling fountains and towering trees, creating an ambiance of tranquility and romance. A meandering garden path leads to a formal foyer, and introduces a stunning living room with marble fireplace crowned by 16' soaring ceilings, and a dining room with wine bar, ideal for grand entertaining and intimate celebrations alike. Numerous arched French doors offer captivating vistas of the glorious outdoors. The gourmet kitchen serves as the heart of the home, featuring a striking glass-turret breakfast room, generous center island and abundant cabinetry. A charming guest suite, an exquisite butler's pantry, laundry room and two powder rooms, complete the west wing. The main-floor sumptuous primary suite is a true sanctuary, showcasing 20' vaulted ceilings, marble fireplace, a sun-lit sitting room, expansive walk-in closet and a spa-like bathroom. An adjacent paneled library, adorned with custom bookshelves, a wet bar and French doors, makes for an ideal home office. A warm and inviting family room offers cozy family evenings, with French doors and a handsome fireplace. Gracing the upper level are three additional generous-sized bedroom suites, a covered terrace and a huge rear balcony with spectacular garden views, providing for restful, private family quarters. Tall arched French doors throughout the home capture the estate's three-quarter-acre wondrous landscaped grounds that unfold into a tapestry of colorful gardens, scenic retreats and al fresco entertaining spaces.
