Overview of Polhemus Residences at 100 Amity Street

Polhemus Residences at 100 Amity Street represents a remarkable transformation of medical history into modern luxury living. Originally erected in 1897 as the Polhemus Memorial Clinic, this historic building gained fame for housing one of the first ever X-ray machines, marking its place in the annals of medical innovation. The building's conversion to a 17 unit luxury condominium in 2019 preserved its architectural heritage while creating contemporary homes that honor its storied past.

The building's French Renaissance limestone and iron spot brick façade was meticulously restored during the conversion, maintaining the grandeur that has defined this Cobble Hill landmark for over a century. The exterior restoration ensures that the building continues to stand as a testament to late 19th century institutional architecture, seamlessly blending historical significance with modern residential luxury.

Each of the 17 residences features loft like interiors with contextually sensitive design that respects the building's medical heritage. The apartments boast windows up to 11 feet tall and voluminous ceilings that create an airy, spacious atmosphere throughout. Custom millwork and bespoke finishes add sophisticated touches, while Gaggenau appliances anchor the kitchens and spa like bathrooms provide resort style relaxation.

Select units enjoy the added luxury of private terraces, offering residents personal outdoor space in this coveted Brooklyn neighborhood. The building's intimate scale of just 17 units ensures an exclusive living experience while providing substantial residences that take full advantage of the building's generous proportions and historic character.

Residents have access to a two level amenity suite that includes a wood paneled billiards library complete with fireplace, creating an elegant space for relaxation and entertainment. The amenities extend to a state-of-the-art fitness center with yoga studio and a rooftop terrace offering views of surrounding brownstones and New York Harbor, providing multiple spaces for recreation and taking in the scenic beauty of Brooklyn's waterfront location.
