## Description

### Agent Description
Completely New Construction, this raised waterfront colonial offers an extensive renovation with all-new electric, plumbing, roofing, heating, and interior/exterior finishes. This masterpiece features an open-concept floor plan with hardwood oak and tile flooring, recessed lighting, quartz countertops, stainless-steel appliances, and high-end finishes throughout. Large Marvin sliding glass doors provide abundant natural light and direct access to the outdoor living areas. Heating and mechanical features include a high-efficiency heat pump, five-zone heating, and a radiant floor heating system. The electrical system includes a brand new 200-amp electrical panel. The exterior features a spacious porch with all-new Trex decking, double balconies, private docking and beach area. This home also includes a detached garage and a raised foundation with ample storage. Tucked away on a quiet dead-end block, with waterfront views to complement your new modern lifestyle this home checks all the boxes. Come experience this home in person-you may never want to leave.
