Positioned within the Alexandria House, #501/510 is a masterfully re-imagined residence that represents the pinnacle of luxury high-rise living in the heart of Old Town, Alexandria. This extraordinary 3 bed and 3.5 bath home is the brilliant result of two individual units seamlessly combined into a singular, sprawling sanctuary boasting over 2,200 interior square feet of fluid, light-filled space. Custom-tailored and proudly featured in the pages of Southern Home magazine, every square inch of the property reflects bespoke craftsmanship, timeless sophistication, and a meticulous attention to detail. Bounded by walls of glass, the space opens to an enormous, (430+ sq ft!) private terrace with river views-a rare high-rise asset that serves as a massive outdoor retreat perfect for al fresco dining and relaxation. Because the home expertly merges two full footprints, it grants the ultimate luxury of abundance-including both a grand formal living room and a separate dining room alongside a highly coveted secondary private entrance. Of the three bedrooms, two include generously sized walk-in closets and en-suite bathrooms. Two large storage units and two garage parking spaces included. Life at Alexandria House elevates daily living with a robust suite of world-class, club-style amenities. Enjoy exclusive access to the spectacular rooftop pool (complete with dedicated baths and spa), a secondary panoramic rooftop sun deck, and a penthouse-level party and catering room with its own private balcony overlooking the city. The full-service secure building also features a full-time front desk attendant, state-of-the-art fitness room, a quiet resident library, and professional meeting rooms. Combining the scale of a single-family home with the effortless convenience of a luxury condominium building, this turnkey property is a true Alexandria unicorn.
