The combination of the 2nd and 3rd floors will create a 7000 sq ft Duplex, one of the largest Flatiron Condo lofts that can be had. Each of the floors are open lofts spanning over 40' wide and and is 82'deep. With soaring ceiling heights of 12.5'-13.5' the ability to create a massive duplex loft home of epic proportions is presented. A very spacious 7 bedroom home can be crafted with 7-8 bathrooms, amazing entertaining spaces including media room, library, home office(s) ,gym, spa, generously sized bedrooms, lots closets & storage staff rooms and more. The massive south facing windows deliver brilliant natural light thru the day. The existing floor plan is shown (both floors have identical floor plates), along with an example of a 7 bedroom option, but the possibilities are endless as there are only 2 small columns on each floor. There are also a few renderings of what this loft can become to help get your creative juices flowing. Bring your architect and your imagination to this boutique condo building made of up of 11 full floor units, with doorman. This building was converted from a commercial condo to residential, so the ability to build out for residential use is as of right
Located on a lovely and quiet block in the heart of Flatiron, this is a wonderful and unique offering that is a must see
