514 West 24th St


This building on 24th Street, was a development which OPEN Architectural Windows and Doors was incredibly proud to be a part of. Located in the heart of Chelsea in Manhattan, the building, whose façade is made up of stunning, green terracotta tile and custom-made wooden and copper window units, is one of the most unique and visually arresting buildings in its district.

Our role in the development was to create the wooden window units, which we did, using a special copper cladding. We also designed matching, copper spandrel panels, which complimented the window units. The combination of terracotta tile and the copper cladding created a uniform look which highlighted and emphasized the building’s art deco design. The natural patina which develops upon copper’s surface also contributed to the architect’s vision for a dynamic, naturally-ageing, or rusting look, for the façade.


In collaboration with the architect, we chose a subtle but elegant, stained white oak for the interior of each of the window units. Its pleasing look brightened up the interiors and provided a neutral space for the interior decorators.

The copper spandrel panels which we designed created the appearance of a harmonious and unbroken façade on the building’s front elevation. The spandrel panels were a combination of copper mullions, welded in single frames, and attached to a larger, copper frame. We installed a vertical, copper fin in between the panels which unified the façade.



We also installed an oversized, walkable skylight on the building’s rooftop. The skylight was installed at a 15° slope and, because of its length (almost 13 feet), offers magnificent views. The unit, which can bear an enhanced load of up to three people, has also been finished with an anti-slip surface. To ensure that the skylight was structurally sound and up to NYC building codes, we used two special, tempered panes of laminated glass.

The architect had envisioned different façades for the front and rear elevations, which meant that we designed the rear elevation slightly differently. The rear façade was complemented by a set of oak windows with matching sills and black brick molds. We used the highest grade white oak and finished it with a specially developed, clear stain.



We know how important first impressions are which is why we paid such close attention to the front elevation entry doors. For them, we used a combination of bespoke touches such as the sleek pull handles and the angular, protruding panels at the bottom of the doors. We were very pleased with how we incorporated these elements into the overall façade.
