new zero-variance proposal to bring Luxury Waterfront Living to the heart of Patchogue

Terwilliger & Bartone Properties is proposing the Cornerstone Waterfront at Patchogue, luxury apartment homes to be located just steps from the Fire Island ferries and near Patchogue Village’s thriving downtown and Long Island Rail Road station .

Feedback from the community has been incorporated throughout the review process to ensure The Cornerstone is a good neighbor, and the current revised proposal has addressed every single concern raised by the Planning Board.

Resident amenities will include a roof top lounge and barbecue with panoramic bay views, rentable boat slips, modern fitness studio, onsite management, clubroom, private parking and more.

NEW Waterfront Promenade Public Amenity

This proposal includes the creation of a Waterfront Promenade as a public amenity with benches and lighting to enhance the aesthetic of the area. We will be installing new permeable (self-draining) brick paver sidewalks from West Ave. down Mulford St. to the new permeable paver public waterfront promenade so community members can access and enjoy the scenic waterfront. Currently, there are no sidewalks, and the road dead ends at the water, but we will transform the area with these improvements for the community using private funds at no cost to the residents.
