10 Greene Street

Façade of luxury 10 Greene St's luxury, rooftop penthouse.

Designed by John B Snook, one of New York City’s most esteemed architects, just over a century and a half ago, this Greene Street building, located in the heart of Downtown Manhattan’s fashionable SoHo district, has recently undergone a dramatic interior transformation as well as a complete restoration to its historic, cast-iron façade. OPEN AWD was proud to be a part of this unique renovation project, and happy to create a series of bespoke, custom windows.

Working alongside the property’s developer, Javeri Capital, OPEN AWD helped breathe new life into the building—which is the oldest cast-iron building on its block—helping convert its five floors into exclusive, luxury apartments.




Today, Greene Street is one of several blocks which make up the SoHo-Cast Iron Historic District—a district famed for its extensive and unique use of cast-iron as a central component in its buildings.

10 Greene Street features typical double-hung windows, and three classic, solid wooden doors on its first floor. A unique, sloped skylight was also installed on the building’s rear elevation. The fifth floor and rooftop is home to a three-story penthouse. The stunning penthouse boasts its own bespoke, ultramodern façade, cutting-edge glazing, a walkable skylight. It also features a sliding door which leads out onto its own rooftop terrace.


For the project, OPEN AWD were responsible for:

● Firstly, carefully reproducing the design of the original storefront doors on the first floor, including the decorative wooden panels.

●Secondly, modernizing the windows to make them more energy efficient, offer more effective protection against drafts, as well as improving their durability and ease of use.

● Thirdly, carefully remodeling the window units and brickmold to restore the building’s historic look.

● Finally, designing custom windows for the rooftop penthouse, including oversized sliding doors, tilt and turn windows, and a walkable skylight

At OPEN AWD, we believe that a façade is one of the most important and delicate components of any restoration project. However, the façades of many historic buildings are often the most under-appreciated and overlooked aspects during renovations. As a result, OPEN AWD ensured that every effort went into carefully restoring 10 Greene Street’s beautiful façade.

This part of the project included the installation of 39 double-hung custom windows. We used the highest quality Scandinavian Pine wood, painted ‘bone white’.  Similarly, we chose two-over-two lites, or six-over-six lites. We felt all of this would more closely resemble the building’s historic design.

Because of slight design issues in some of the previous window units, we approached each window unit separately during the shop drawings stage. In order to create a seamless façade, we designed a series of unique brickmold details for each unit. As a result, this ensured that all gaps between the window frame and the existing opening were adequately joined.
Then, OPEN AWD installed a twenty-six-foot wide, sloped skylight on the building’s rear elevation. We were able to incorporate the unit into the building’s original design. Moreover, we also felt that this would provide some additional light and thermal efficiency.


Modern Penthouse

The two uppermost floors of the penthouse were fitted with sliding doors. These door provided a vast amount of natural light for the entire unit. Then, a walkable skylight was installed on the terrace on the penthouse’s third floor. Similarly, the skylight helped to open the space up further. Lastly, a unique frameless, floating corner window was fitted into the second-floor façade.
