Introducing a rare, proposed construction opportunity on one of Hampstead's most sought-after waterfront parcels. This high, cleared .44-acre lot at 113 Mallard Drive offers deep-water canal frontage with 4+ feet of depth, a protected setting, and direct access to the Intracoastal Waterway just minutes away. Already in place are two 45-foot boat slips, a floating dock, and new bulkhead, creating the ultimate setup for boating enthusiasts and allowing you to enjoy the waterfront lifestyle immediately--even while your home is being built. The proposed home showcases a spacious and thoughtfully designed coastal floor plan featuring approximately 3,100 heated square feet with 4 bedrooms and 4 full baths. The main level offers a luxurious primary suite with spa-style bath, dual vanities, and walk-in closets, along with an open-concept living area highlighted by vaulted ceilings, abundant natural light, and a gas fireplace. The chef's kitchen is designed for both entertaining and everyday living with custom cabinetry, quartz countertops, an oversized island, gas cooktop, double ovens, and walk-in pantry, complemented by a formal dining area and breakfast nook. A secondary first-floor bedroom with adjacent full bath provides flexible living options, while upstairs includes additional bedrooms and a large bonus or game room. High-end finishes such as quartz surfaces throughout, custom trim and built-ins, designer lighting, and a blend of LVP, tile, and carpet flooring elevate the home's craftsmanship and coastal appeal. Offered as a proposed construction package with a builder-owner, buyers have the flexibility to select this floor plan, customize it, choose an entirely different plan, or purchase the lot separately. Seller may consider partial owner financing with a substantial down payment, making this a unique chance to secure a premier waterfront homesite and create a tailored coastal retreat.
