Description
This exceptional 2nd-floor open loft is an expansive canvas, stretching over 40' wide and extending 82' deep. Boasting soaring ceiling heights of over 13.5', this remarkable space presents a perfect opportunity to craft a dream-like 3500sq ft loft home. The potential is vast, allowing for a generous 4-bedroom residence with 4-5 bathrooms, extraordinary entertaining areas, well-proportioned bedrooms, ample closets & storage, and a media room. A flood of natural light enhances the ambiance, creating an inviting atmosphere.
The existing floor plan is thoughtfully provided, along with an illustrative example of a 4-bedroom layout. However, the possibilities are limitless, thanks to just 2 small columns within the entire expanse. Renderings further inspire the creative process, offering glimpses of the loft's boundless potential. Collaborate with your architect and unleash your imagination in this exclusive boutique condo building comprised of 11 full-floor units, complete with a doorman. This building's seamless conversion from commercial to residential condo grants the as-of-right privilege to build out for residential use.
