On Saturday 10/17 and Sunday 10/18, the Annual Open House New York Weekend will unlock the doors of New York’s most important buildings, offering an extraordinary opportunity to experience the city and meet the people who design, build, and preserve New York.  From historical to contemporary, residential to industrial, hundreds of sites across the five boroughs are open to visit, with tours, talks, performances, and other special events taking place over the course of OHNY Weekend. Through the unparalleled access that it enables, OHNY Weekend deepens our understanding of the importance of architecture and urban design to foster a more vibrant civic life, and helps catalyze a citywide conversation about how to build a better New York.

This year, OHNY includes a special focus on structural engineering and will feature two GMS projects for which tours will be curated by our staff.


To create an iconic new flagship showroom for tile, kitchen, bathroom and hardwood company Porcelanosa, Foster + Partners, working with structural engineers from Gilsanz Murray Steficek, created an entirely new structure within the historic Commodore Criterion building. The result is a dramatic, light-filled, six-level showroom that includes a design library with more than 1,000 references of tiles, mosaics, stones, and hardwoods in a dramatic, top-level space. On OHNY Weekend, tour the newly opened showroom with architects (on Saturday) or structural engineers (on Sunday) to learn about how they crafted a dynamic, highly flexible new sequence of spaces within the building’s landmarked shell.

Stapleton Library

The Stapleton Branch of The New York Public Library, which originally opened in 1907, is located on Canal Street, near the center of Stapleton Village and adjacent to Tappen Park and the Old Village Hall. The graceful, single story, brick and limestone building was constructed with funds provided by Andrew Carnegie and designed by Carrére and Hastings. The library was closed in 2010 for extensive expansion and renovations, and reopened on June 11, 2013, to great fanfare. As the Structural Engineers for the renovation, guides from Gilsanz Murray Steficek will discuss the challenges of working with existing buildings and the design for the new addition.
