SIZE
25,000 sqft - 100,000 sqft
6 Cortlandt Alley/372 Broadway
Two stories penthouse addition in a Landmarked District
Tribeca, New York City, 2014
7Stories, 37,000 SF, 7 Units
Adaptive reuse/Preservation, two stories Penthouse addition
TThe loft building, one of the oldest in the area, constructed in 1852 ,was in an advanced state of abandonment, in the engineers' words," four walls at the end of life" . The historical significance of the old structure guided the design process, whose strategy has been developed with the goal of preserving all the surviving original elements of the building, differentiating the new with contemporary systems and languages, the tension giving a second life to the building's soul.
This project is very much representative of our studio's work in the historic districts; as the word TRA exemplifies, the design finds a balanced equilibrium between, preservation, regulations and practical constraints, uncovering opportunities for wonderful spaces , “above-below-in between” the massive structure.
The lot is very unique, because it spans the entire block, being 150' long, and because it is adjacent to a 26 storey mediocre apartment tower. The zoning imposed the separation of the lot in two, with all of the bulk of the addition to be located on the Broadway side, contiguous to the tower. TRA was instrumental in navigating the restrictive zoning requirements in order to build the 3,800 sf two floors addition.
The design of the penthouse, contrary to the rule of thumb that additions should not be limited to one level and minimally visible, entails, on Broadway, a fully visible contemporary two storey volume..
Responding to the difficult restrictions imposed by zoning, the strategy for the design of the proposed 3,800 sf rooftop addition, refers to a particular condition seen only on lower Broadway, where the top two floors often sit above a first cornice, a building on top of a building. The proposed upper “building” maintains a balance similar to the volumes that animate the nearby roof-scapes. The chamfered sky-lit roof, (the only modification of the window wall acceptable at the DOB) and the articulation of the volumes morph the “upper building” into a large skylight, offering a gentle transition to the old historic loft structure on the south. The design was unanimously approved after one Public Hearing session, by the New York City Landmarks Preservation Commission, following minimal modifications
On the Broadway side, the architectural elements and infill of the first floor have been previously completely removed. The 372 Broadway proposed storefront shows the reintroduction of the missing columns, interrupted by the retail display window. This recalls the projecting storefront seen often in the area and also refers to Gio Ponti’s furnished windows, where the inserted display elements, interrupt the structure, extending the pattern of the design of the fourth wall. The clarity of the storefront design brands not only the multi-level retail, but also the development project.
The other issue that was critical was the need to inject light and air into each unit, each apartment has its own private, dramatic interior atrium, Across the atrium, you can only see the other wing of your own unit, similarly to the courtyard buildings in Barcelona, the atrium is the center of the apartment, one of the most desirable features, providing unexpected views.
On Cortlandt, the design takes full advantage of the multiple underground cellars and the difference of level between Broadway and Cortlandt, turning what was an hidden space into an expansive lobby.
