Façade Restoration Receives Honors

The 1874 cast-iron building in NoHo is a New York City landmark and on the National Register of Historic Places.

The $4.5-million façade preservation and restoration of 54 Bond St., a circa-1874 cast-iron building in New York City’s NoHo District “was an extremely involved, painstaking process involving extensive restoration as well as the replication of over 1,000 incredibly intricate cast-iron units, including formed metal cornices and pediments. In addition to the extensive cast iron, there is sheet-metal ornamentation on the façade, on elements such as the cornices. All renovation work was performed from pipe scaffolding,” according to Christa E. Waring, AIA, LEED AP, principal in charge, CTA Architects PC, New York (ctaarchitects.com).

The project received a 2018 Lucy G. Moses Preservation Award, the New York Landmarks Conservancy’s (New York, nylandmarks.org) highest honors for preservation excellence.

The highly ornate, six-story, 15,000-sq.-ft. 54 Bond St. building in the Bowery section of the NoHo Historic District was designed by Henry Engelbert and constructed between 1873 and 1874, at a time when the Bowery was a residential and cultural center. Columns surround the windows and a stately cornice was specified for above the sixth floor. A shallow pediment is on the Bond Street side of the building, while Englebert placed a cornice around the building between each floor, to unify both sides of the façade.

The structure served as the Bond Street Savings Bank for five years. As the Bowery declined, the structure became home to the German Exchange Bank, then a loft and storage space, and, after that, the Bouwerie Lane Theater in 1963. The New York City Landmarks Preservation Commission (LPC) designated the building an individual landmark in 1967, and it was placed on the National Register of Historic Places in 1980.

In the mid-2000s, the Bowery began to improve. It was in 2007 that 54 Bond was purchased and converted into a condominium property with three large high-end residential lofts and two commercial spaces on the first two floors. A few years later, the owner, 54 Bond Street Condominium, contracted CTA to repair the façade, as it had become somewhat dilapidated. Cast-iron units along the façade were heavily rusted and/or deteriorated, for instance, while there were a number of points of local leakage. CTA, which has extensive experience with historic restorations and residential buildings, not only restored the façade to its original condition and addressed the leakage, it restored the brick masonry parapets on the northwest side of the structure.

CTA designed the facade repair, bid out the project, and performed construction-administration services, developing the budget and the trade packages. Before any renovation work was undertaken, however, CTA’s project manager, Matthew Jenkins, AIA, performed an intensive and detailed three-month-long documentation of the façade for two primary purposes: to assess and document the façade’s condition; and to ascertain which cast-iron units would need to be replaced.

“It was amazing to see just how detailed each unit was. The intricacy and the decorative and interlocking nature of each unit made it a challenging undertaking,” Jenkins said. He also uncovered some hidden conditions, and stated, “When the units were removed, we found that the cast-iron braces that held them in place had deteriorated, along with the brick-and-masonry backup.” Since these items had to be addressed, they were added to the scope of the project.

Full Scope Of Work

Most cast-iron buildings are narrow, so their facades are limited. However, 54 Bond is unusual in that it is on a corner. Hence, the amount of cast iron is much more extensive on it than on most cast-iron buildings. In fact, the Bond Street side alone is more than 100-ft. long.

Due to the façade’s beauty and uniqueness, as well as its landmarked status, CTA was careful to avoid using alternate materials that differed from those originally used. In fact, the only modern material the team used was concealed sheet flashing to protect the building’s interior from water penetration.

All of the cast-iron units to be replaced were numbered, shipped to the Belgium-based cast-iron fabricator Van Cronenburg Architectural Hardware (petervancronenburg.be) facility in Ghent, and reviewed in detail, allowing the fabricator to create shop drawings, molds, and then create replicas. The cast-iron pieces were also zinc-metalized to provide additional rust protection and then painted with three coats of epoxy paint. Pieces that were in good condition, on the other hand, were stripped of paint and rust and were then recoated in a phased process.

Due to the architectural significance of the building, the team worked with the coating manufacturer, Tnemec Co. Inc., Kansas City, MO (tnemec.com), to develop a system for testing the paint, to make sure it adhered appropriately to each element.

CTA’s Bradley Heraux, technical manager on the project, noted that the team’s biggest challenge was coordination. “The cast-iron units were molded and replicated in Belgium, while the sheet-metal elements were remade locally in Long Island City by Gotham Metalworks (gothammetals.com). There were so many different elements in different geographical locations, we really had to coordinate it all very carefully,” he said. “The team collaboration was superb despite the geographical distance,” Heraux continued. In fact, the Belgians traveled to Manhattan for an extensive site review and to create additional documentation of the façade elements.

The façade preservation was an extremely involved, painstaking process involving extensive restoration as well as the replication of more than 1,000 incredibly intricate cast-iron units, including formed metal cornices and pediments.

Overall, in order to make the restoration easier and to avoid dust, the contractors removed old paint using a stripper tape impregnated with solvent, rather than by sandblasting. Further, as the windows were recently replaced, the façade renovation team simply repainted them to match the color of the renovated façade.

After the façade work was completed, the second phase began with the replication of the three original cast-iron entrance stairways leading to the ground floor, which is elevated above the street level. One entrance goes to the residential portion of the building, while the other two belong to the retail portion. At some point over time, the stairways had been replaced. CTA designed new stairs to match the originals the team had found in old photographs and from remnants on site. In addition, CTA added new perimeter areaway fencing, ensuring it was visually attractive and meeting the current codes. The final steps are to replace the sidewalk and renovate underground vault, as well as to restore the historic areaway.

CTA worked with the Landmarks Preservation Commission throughout the process. All processes, materials, and equipment had to be approved by the agency, even the security cameras installed on the building. Low-profile cameras were installed so as not to detract from the aesthetics.

New York’s Bowery has seen its ups and downs, but the 54 Bond St. restoration preserves an example of its impressive history.
