The Carlton House

Situated prominently at the gateway to the Upper East Side Historic District in Manhattan, 680 Madison Avenue is a 15-story building originally conceived in 1951 as a residential property and then converted into The Carlton House Hotel. BBB's transformation of the building to its current use as a condominium residence included reconfiguring interior layouts, restoring the exterior façades, and adding floor area and common amenities to the building. The residential floors feature all new finishes, circulation core and mechanical systems; the retail space is reconfigured to provide maximum leasing flexibility and contiguous space; and the facades are restored to their original splendor through a comprehensive window replacement program and masonry repair. BBB's work also includes the design of a new 10,000 SF single-family townhouse adjacent to the existing building, which houses the entrance to the development.
