Are you ready to build? Skip the multi-year BPAS waitlist and start construction of your Florida Keys dream home on Day 1! This shovel-ready, 6,000 sq ft Grassy Key lot comes with a fully active City of Marathon building permit, local contractor, and ready-to-go blueprints for a stunning 1,500 sq ft, 4-bedroom primary residence. With the plans already approved at the state and city level. Begin breaking ground immediately upon closing. The seller has completely taken stress out of starting the building process-spending over $45,000 to deliver a cleared site complete with a construction driveway, mandatory safety fence, temporary electric pole, and surveyed corners. The plans are updated to the latest strict building codes, your builder can mobilize immediately while allowing you to fully customize the interior finishes to your exact taste. Well above the base flood elevation for optimal safety and insurance savings, this home plan is designed to capture breathtaking water views from a massive 23-foot outdoor deck. The luxury primary suite serves as a private oasis, boasting a standalone soaking tub positioned perfectly against a dedicated viewing window with glimpses of the water, alongside a separate walk-in shower. Engineered for the ultimate coastal lifestyle, the specifications feature a premium metal roof, ultra-durable HardieBacker siding, and high-efficiency green additions-including an integrated cistern for rainwater collection and an innovative AC heat-recirculator for the water heater. If you are a local resident, down-sizer, or professional looking to establish your primary homestead in the Keys without the years of bureaucratic delays, this turnkey property offers an unmatched head start. Ideally located just moments from Sunset Bay Park, where you can launch a kayak, enjoy breathtaking nightly sunsets, and watch local marine life glide through the clear waters. Embrace the true Keys lifestyle. Seller is a licensed real estate agent.
