Project Description

This project involves the demolition of the existing New York City landmarked building and reconstructed of a new nine-story building. The building features a new two-story penthouse, plus partial third floor elevator bulkhead. DRPILLA is responsible for the design work associated with the comprehensive reconstruction, side yard expansion, ground floor expansion and the restoration of the existing façade, as part of the Landmark Preservation Commission requirements.

Integrating the Preservation and New Construction of a Historic Building

The DRPILLA team produced a thoughtful composition for the vertical expansion of this historic building to accommodate strict approvals from the Landmarks Preservation Commission. The new rooftop addition was designed to interface accordingly with the existing unreinforced masonry façade and provide comprehensive stability. The entire building is being demolished and reconstructed to form a nine-story building. The top two floors are being set back 28 feet from the front of the building.

Reconfiguring the Structural System

Construction consists of steel and concrete floors with masonry shear wall construction. The rear façade of the building will be reconfigured to accommodate new balconies and terraces. Full height lateral steel braces were provided to support the façade during the interim while the new building structure was being completed.
