Each day in the month of October, a different building in New York City will open its doors to visitors who want to learn about the structure’s unique architecture. The Building of the Day program presented by Archtober, a month-long celebration of NYC architecture and design, brings the public inside the city’s most amazing spaces for architect-led walking tours.

Building of the Day tours are presented by the Center for Architecture and are hosted across all five boroughs. While many are already sold out, there are still plenty of fascinating buildings you can gain access to. Don’t wait too long! Check out all of the buildings below.

Untapped New York is also hosting a variety of Archtober events this month! Join us to explore the architecture of Grand Central, track down remnants of the original Penn Station, visit the Gilded Age mansions of 5th Ave, and more! Untapped New York Insiders can also sign up for a free ticket to Archtober’s annual pumpkin carving contest, Pumpkitecture! Limited spots are available.

Adapting St. Luke’s Hospital by Ernest Flagg, 1896-1928, into apartments within five French Renaissance Revival-style pavilions across from Morningside Park, the conversion builds on Flagg’s maximizing light and air around a central carriage house–later a standard for hospital design. The conversion resolves varied floor heights and structural systems, adding infill buildings. Inside, unconventional duplexes with double-height living rooms behind mansard roofs open residents to the carriage house’s new, double-height resident lounge with vaulted ceilings.

October 7th – East Flatbush Library

12:00pm – 1:00pm
Address: 9612 Church Ave. Brooklyn, NY 11212 United States
Get tickets!

The renovation of the East Flatbush Branch Library represents a key moment in the public life of this community. As the affluence of the city increases and income levels and services in neighborhoods like East Flatbush rise accordingly, but at a far lesser rate than other areas of the city, there exists an opportunity to make these key public buildings more transparent, vibrant and architecturally participatory in the life of the street. At the same time, the need for security and safety for the people who use the library remains. To address this opportunity, the design intent for the library is a light-filled communal space of learning, self-improvement and community gathering. The overall design establishes a large central space with glowing smaller spaces ringing the perimeter and provides the technical and spatial needs for the branch library to flourish.

October 8th – The Perelman Center for Performing Arts

The adaptive reuse of One Madison Avenue adds an 18-story tower atop an updated, mid-century podium.

The design retains 67% of the building’s original structure, preserving a significant amount of embodied energy, and is forecast to result in an energy reduction of over 60% against the AIA 2030 Commitment baseline. The project is designed to comply today with the 2030 building emission targets determined by NYC’s Local Law 97. Please note: this tour is not accessible by wheelchair.
