Open WaterDockOnly

This dock fronts open water — a bay, harbor or marina basin rather than a canal.

There is no across-the-canal bank here, so no canal width applies and boat length is not limited by room to turn around. Check depth, beam and slip dimensions with the listing agent.

Description

Boaters will love this spacious elevated home in a premier waterfront location on Longboat Key with dock, lift and by boat it is just four homes from the intercoastal, open bay waters and a short boat ride to the Gulf. Built for large gatherings, this home is beautifully designed with loads of gathering and entertaining spaces. The open plan home was thoughtfully designed with five bedrooms, four with en-suite baths. The kitchen features custom wood cabinets and granite countertops. Entertaining will be a breeze with two large gathering spaces, including a great room with dining area and adjacent bonus room that would be a wonderful media or game room. Ground level highlights include two bonus areas and a huge four-car garage. The composite dock has a 10,000-pound boat lift, water and electric. Recent updates include hurricane windows and doors (2025), metal roof (2025), pool equipment and pool heater (2025) and interior freshly painted. This location on Longboat Key can't be beat with community beach access just across the street, and a heated pool and boating in your own backyard. This is the ideal home to create wonderful island memories.

Navigation note: Navigation routes show the shortest mapped path to open water. A vessel taller than the binding bridge clearance may still reach open water via a longer alternate route that we don't currently map. Verify navigability with a local captain or surveyor before relying on it.
