Property Description
Rare opportunity to build new on an oversized waterfront lot in the Florida Keys. Situated on a 10,400 square foot lot the property already has a pool, dock and 10Klb. boat lift in place giving you a great head start on creating your own home on the water. Plans have already been completed for a 3 bedroom 3 bathroom home designed for the property, with renderings available to help bring the vision to life. Build new without having to start completely from scratch while still having the opportunity to select finishes and make the home your own. Permit on hand. With plenty of outdoor space, direct access to the water and boating right from your backyard this is a unique opportunity to create a new waterfront home in the Keys.
