This building known as the Obsidian House was built in 1857 by one of New York’s most prominent families, becoming one of the first cast-iron buildings in the City's downtown. Today - thanks to its renovation in 2015 - the Reade Street building has reemerged and is once again one of Tribeca’s most striking residences.

In 2015, the cast iron building at 93 Reade Street was redesigned by the WORKac firm, run by the married architects Dan Wood and Amale Andraos. Now, the new Obsidian House is a 10,000 square foot loft renovation and penthouse addition, which have been updated in a way that honors its rich history. The design responds both the existing 5-storey structure and its context. The architects has implemented innovative alternatives to very complicated problems and they have proposed spaces which are provided with lots of opportunities. 
 

Project description by WORKac

This residential development consists of a complete gut renovation and new construction behind one of New York’s most beautiful and oldest cast-iron facades. It required a careful approach to the blending of contemporary architecture with historic preservation. New York City’s Landmarks Commission required any rooftop addition to be invisible. The building, however, is located on a highly-visible corner with a low, two-story building across the street. This meant that the building’s roof was visible from almost three blocks away.

Tracing the cone of vision from the furthest point from which the building was visible, WORKac utilized three rooftop projections to mask the bulk of an addition: the triangular pediment of the historic Carey Building next door, and the circular pediment and an abandoned elevator bulkhead  at the top of the building itself. The “shadow” created by these three projections created a sizeable zone for the addition and the opportunity for a distinctive angled form for the new roof. The result is a sculptural form that is – at the same time – completely invisible from the street below.

For the apartment interiors and public area, WORKac created spaces that combine nature-inspired elements and systems with new ideas about urban living. From the tessellated green wall at the lobby to generous planters and balconies at the second, sixth and seventh floors, connections to the outdoors are emphasized. Within each apartment, a “third space” between bedrooms and living spaces is created at the top of the volume containing storage and bathrooms. Less than four-feet high, this “bonsai apartment” is outfitted with a futon, seating areas, and an herb garden above the kitchen. Its main feature is a fern garden connected to the master shower below. Steam from the shower collects on the glass walls of the garden and waters the plants.

The penthouse combines sleeping spaces and a family room within the old fifth floor of the building with new entertaining and dining spaces under the new roof at the sixth floor. A secluded terrace is sunken behind the pediment with views to the Woolworth Building; the old elevator bulkhead is repurposed with a hot tub. The height afforded by angle formed by the cone-of-vision allows for a rear mezzanine with views toward downtown and the Freedom Tower.

The 1857 façade is completely restored. The new charcoal color chosen by WORKac references the building’s history of being painted in dark contrast with its lighter neighbors. As all of the building’s Corinthean column capitols had been lost to history, WORKac collaborated with the artist Michael Hansmeyer to create new versions. Hansmeyer created a computer script that allowed the classical floral elements of the Corinthean order to “grow” fractally, resulting in a new design that adheres to the old proportions but is composed of clearly new forms and idiosyncrasies.  Like the rooftop addition, these capitals at first glance appear quite ordinary; it is only on closer inspection that the stealthy strategy of strategic injection of contemporary design becomes clear.

WORKac is interested in positing architecture at the intersection of the urban, the rural and the natural. They embrace reinvention and collaborate with other fields to rethink architecture ‘in the world.’ In the face of overwhelming challenges and increasingly normative scenarios, they remain stubborn in our commitment to imagine alternate scenarios for the future of cities. They appropriate the more productive aspects of the urban discourse – from density and compression, to appropriateness of scale, the expression of intelligent and shared infrastructures, and a more careful integration between architecture, landscape and ecological systems – to bear upon architecture as we find shared concerns across their global practice. They hold unshakable lightness and polemical optimism as a means to move beyond the projected and towards the possible, an ambition with which they approach every project.

Dan Wood, FAIA, LEED AP, leads international projects for WORKac ranging from masterplans to buildings across the United States as well as in Asia, Africa, and Europe. Wood holds the 2013-14 Louis I. Kahn Chair at the Yale School of Architecture and has taught at the Princeton University School of Architecture, the Irwin S. Chanin School of Architecture at the Cooper Union, Columbia University’s Graduate School of Architecture, Planning, and Preservation, Ohio State University’s Knowlton School of Architecture, and the UC Berkeley School of Environmental Design, where he was the Friedman Distinguished Chair. Wood is originally from Rhode Island and lived in Paris and in the Netherlands for many years before moving to New York in 2002. He is a licensed architect in the State of New York and is LEED certified.

Amale Andraos is the dean of Columbia University’s Graduate School of Architecture, Planning and Preservation. She has taught at numerous institutions including the Princeton University School of Architecture, the Harvard Graduate School of Design, the University of Pennsylvania Design School, and the American University in Beirut. Andraos is committed to research and publications. Her work has recently explored the question of representation by re-examining the concept of the ‘Arab City.’ Andraos was born in Beirut, Lebanon. She has lived in Saudi Arabia, France, Canada, and the Netherlands prior to moving to New York in 2002. She serves on the board of the Architectural League of New York, the Advisory Board of the Arab Center for Architecture in Beirut and is a member of the faculty steering committee for the Columbia Global Centers | Middle East.
