Howard L. Zimmerman Architects, P.C. oversees renovation of New York’s The Plaza’s façade

The Plaza, one of New York’s historic hotels, has announced the completion of an extensive exterior renovation, presenting a restored façade.   As a part of New York history, The Plaza Hotel’s architecture has been an icon in Manhattan’s landscape since 1907, when the French Renaissance chateau-style hotel first opened.

Restoring a part of New York’s historical architecture, the renovation of its façade, which was designed by Henry Janeway Hardenbergh, included the replacement of ornamental terracotta, as well as the extensive restoration of deteriorated terracotta, brick and marble.  It also involved waterproofing and roofing repairs, and a final thorough cleaning.

The two-year restoration required that original façade elements were repaired and, in some cases, recreated, requiring the use of historically compatible mortar, custom-colored patching compounds, and custom-made molds.  Matching the color and hardness of the mortar was essential to ensuring that the building maintained its historic look. The historic mortar was analyzed and a mortar with matching characteristics was used.

Custom molds were created from original remaining elements to retain the historical integrity throughout the renovation.  The marble bosses on the fourth floor balconettes have now been replaced with new concrete molds that were casted from the remaining original marble bosses.  On the fifteenth floor, many of the original balusters had severely deteriorated.  Comprised of elegant volutes and circles, and flanked by ornate pilasters, these deteriorated balusters were replaced with custom molds created from the original pieces and matching the original finishes.  Several units were hand carved to create a perfect match.

The roofs on the fifteenth floor balconies were restored with new “Patina Green” roofing and were restructured to facilitate proper drainage.  On the Fifth Avenue façade, new copper patina leaders were installed to discharge water away from the masonry.

This renovation was overseen by Howard L. Zimmerman Architects, P.C., a firm that specializes in the restoration, preservation, and alteration of historic buildings.  

The Plaza features lavish hotel rooms, destination restaurants, an exclusive retail collection, and meeting and event spaces within its restored façade.  The hotel offers 282 guestrooms and suites, including 102 suites in seven distinct designs and layouts.  Public spaces include The Grand Ballroom, The Terrace Room, The Palm Court, The Champagne Bar, and The Rose Club.

Amenities include Shops at The Plaza, as well as Caudalie Vinotherapie Spa, Warren-Tricomi Salon, The Todd English Food Hall and The Plaza Food Hall.

The Plaza Hotel is managed by Fairmont Hotels & Resorts.
