Welcome to the "Washington House," a breathtaking Mediterranean estate on the National Historic Registry and one of the first homes ever built on coveted Davis Islands. Designed by a premier architect of the era, this 1927 masterpiece has been meticulously restored and fully modernized to blend timeless architectural romance with today’s highest luxury standards. Situated on two expansive corner lots, the property is fully enclosed by a private masonry wall with gated entries, new aluminum balcony railings, and a three car garage. The resort style grounds feature manicured gardens, ambient LED lighting, a water fountain, a gazebo, and a sparkling pool with a charming patio and outdoor fireplace. The grand main residence (four thousand four hundred seventy-five square feet) showcases beautifully preserved and resurfaced original 1927 doors. An impressive original wood door opens to a breathtaking circular foyer with soaring ceilings and brand new marble flooring. The open layout flows seamlessly to a spacious formal dining room and a fully remodeled gourmet kitchen. The kitchen is equipped with rich white shaker cabinetry, a new tile backsplash, bright quartz countertops, and premium new Viking appliances. A versatile den/fourth bedroom with an attached half bathroom sits just beyond. The opposite wing features a massive formal living room with a fireplace, a sunroom, and a large family room opening directly to the covered poolside patio. Upstairs, a staircase lined with historic casement windows leads to a serene primary suite complete with hardwood floors, three closets, a historic bathroom, and two private balconies. Two additional guest bedrooms (one with a front-facing sitting room; one with a private balcony) share an stunningly updated full bathroom located right next to the newly renovated laundry room. Maximizing the estate's versatility is an one thousand two hundred sixteen square foot two story guest house with two separate private entrances. The first floor offers one bedroom, one full bathroom, and living area; the second floor features one bedroom, one half bathroom and living space. Enjoy ultimate peace of mind with extensive top tier upgrades: brand new three-ton HVAC system including air handler along with all new ductwork; updated plumbing; new interior/exterior trim paint; upgraded modern bathrooms throughout. A true private luxury enclave!
