Historic Stone Restoration at the National Arts Club
 
Quarra Stone Company provided specialized stone restoration, fabrication, and carving services for the restoration of the historic National Arts Club at 15 Gramercy Park South in New York City. The project restored the building’s iconic Victorian Gothic façade — originally designed by celebrated landscape architect Calvert Vaux — preserving one of the city’s most treasured architectural landmarks and a defining presence on Gramercy Park.
 
Decades of exposure had taken a visible toll on the building’s red sandstone ornamentation. Pediments, decorative moldings, and finely carved details that once gave the façade its Gothic character had eroded, cracked, or been lost entirely. Restoring the building meant more than patching what remained — it required recreating entire architectural elements from scratch, each one matching the scale, proportion, and expressive detail of Vaux’s original design while satisfying the exacting standards of a landmark preservation project.

To achieve that level of fidelity, Quarra combined modern technology with time-honored craft. High-resolution laser scanning captured the existing and surviving historic profiles in precise detail, which were then translated into digital models to guide fabrication. CNC carving roughed out each new stone element with accuracy and consistency, while skilled hand carvers refined every surface — sharpening details, restoring texture, and bringing back the subtle irregularities that give hand-worked stone its character. This blend of digital precision and traditional artistry ensured that every replacement piece integrated seamlessly with the surrounding historic fabric, virtually indistinguishable from the sandstone Vaux’s craftsmen carved more than a century ago.

The completed restoration renewed the building’s Gothic silhouette along Gramercy Park, safeguarding an irreplaceable piece of New York City’s architectural heritage for future generations. In recognition of this achievement, the project received the 2026 Lucy G. Moses Preservation Award from the New York Landmarks Conservancy — the organization’s highest honor for excellence in historic preservation.
