Property Description
Welcome to this exceptional homesite in Aqualane Shores located on Egret Channel with rare long water views down Ibis Cove and across to Aqua Cove. Unlike many canal-front properties, the view extends beyond the immediate waterway, creating a greater sense of openness and visual depth enhanced by the surrounding luxury residences. It is approximately 0.34 acres with approximate dimensions of 100-by-150 feet. There is direct Gulf access with no bridges. The homesite is ideally situated just a few blocks from the beach, 3rd Street South and the dining, shopping and entertainment of Olde Naples. The former residence has just been removed with demolition now complete, presenting a cleared homesite. An existing dock and lift are present; however, their condition is unknown and should not be accessed. This is an exceptional opportunity to build a custom waterfront residence in one of Naples' most desirable waterfront neighborhoods.
