Tucked away on one of the most desirable streets in Old Town, 628 William Street is a stunning blend of Key West history and contemporary sophistication. With over $900,000 in renovations since 2022, this home has been completely reimagined from top to bottom, offering the perfect balance of timeless charm and modern luxury. Step inside to light-filled living spaces featuring new flooring, custom LED lighting, and high-impact windows and doors that fill the home with natural light. The kitchen impresses with all-new Bosch appliances and a striking centuries-old cabinet framing the sink â€' a rare and true conversation piece that adds warmth and character to the sleek modern design. Every detail has been meticulously curated, from the freshly painted interiors and exteriors to the fully renovated bathrooms adorned with high-end finishes. The flexible floor plan includes an optional fourth bedroom, currently styled as a cozy TV lounge. Upstairs, two generous primary bedrooms each offer ensuite bathrooms, creating serene, light-filled retreats. The third bedroom, now an elegant office, overlooks the pool and outdoor living space, blending functionality with tranquility. Outside, the transformation continues with a completely redesigned yard, featuring a custom outdoor kitchen, new awning, and cedar-finished shed. The resort-style pool, with a section extending beneath the house, introduces an architectural feature unlike anything else in Old Town. Behind the scenes, every system has been upgraded, including a new Miele washer and dryer, HVAC and insulation improvements, new pool equipment, rain drainage system, and a whole-house Generac generator. This property embodies luxury island living â€' where history, design, and craftsmanship converge just steps from the best of Old Town Key West. 628 William Street isn't just a renovation â€' it's a complete reinvention of island living.
