ARCHITECTURAL MASTERPIECE

STILLNESS MEETS STRUCTURE
Created by renowned developer Joshua Gurwitz in collaboration with Gabellini Sheppard, Design Workshop, and master builder Mayfair Construction, 140 Hayground Cove is a newly constructed estate that masterfully blends bold Brazilian Modern aesthetics with refined, minimalist design.
With an anticipated completion at the end of 2025, this exceptional residence is set on 2.8 acres+/- and abuts a 2.2 acre+/- nature preserve, offering over 5 acres+/- of rare, uninterrupted privacy. Spanning 12,900 SF+/- of meticulously crafted living space across 2 levels, the home features 7 bedrooms, 9 full and 2 half bathrooms, all finished with cutting-edge materials and uncompromising attention to detail.

The estate’s interior showcases expansive water views and seamless indoor-outdoor flow, with subtle Japanese Teahouse influences that lend serenity and balance to its bold modern form.

LOCATION
Set South of the Highway, this exceptional estate offers unparalleled seclusion at the end of a quiet cul-de-sac. Positioned on the Eastern Shores of Hayground Cove, the property spans over 175’ of direct water frontage+/and boasts sweeping, western-facing views of the Cove, a serene private pond, and the surrounding 2.2 acre+/- private reserve. The estate features a private dock on Hayground Cove with water connectivity to Mecox Bay.

Joshua Gurwitz is a visionary designer and developer celebrated for creating luxury residences that blend innovation with timeless elegance. His latest project at 140 Hayground Cove Road embodies this ethos— an extraordinary waterfront estate where Japanese Teahouse serenity meets Brazilian Modern boldness.
To bring this vision to life, Gurwitz tapped Mayfair Construction, a firm renowned for executing some of the Hamptons’ most complex, ultra-luxury builds—including multiple $100M+ oceanfront estates. Their precision, craftsmanship, and technical mastery ensure the home’s flawless realization.
This distinguished team also includes Gabellini Sheppard for architecture, Design Workshop for landscape design, and Henrybuilt for bespoke millwork— each contributing to the estate’s seamless fusion of architecture, nature, and modern luxury. Cooley Monato Studio enhances the atmosphere with sculptural lighting, Realm integrates advanced home technology, and Summerhill Landscapes brings the grounds to life with natural artistry.
Every detail—from the interiors to the landscape—reflects a shared pursuit of beauty, precision, and enduring quality. The result is a residence that redefines waterfront living: a sanctuary of modern design and timeless sophistication.
