The East and West Buildings of the National Gallery of Art are home to thousands of masterpieces, as well as significant works of architecture in their own right. To preserve these historic buildings and improve their accessibility, energy efficiency, and infrastructure, the museum is committed to its Master Facilities Plan, an ongoing, phased approach to long-term repair, restoration, and renovation.

Major renovations to the north side of the East Building were completed in 2016. Since 2019, additional work has been underway to renovate the galleries on the west side, improve accessibility throughout the building, overhaul select building systems, and replace the iconic Atrium skylight, which is original to the building and over 40 years old. Skylight replacement will be completed in early 2022, followed by art reinstallation in the Atrium. 

This phase of renovation work was designed around the priority of remaining open to the public throughout construction. The East Building has been closed since March 2020 due to the COVID-19 pandemic. Once the East Building reopens, most of the galleries, the Atrium, and other public locations will be available for visitors to enjoy.

The major elements of this phase of work include: 

Atrium Skylight Replacement
Summer 2020 — early 2022

The Atrium skylight is a critical component of the East Building architecture, but one in need of repair after 40 years.  To replace its 23,000 square feet of glass, the National Gallery has installed an elaborate system of sliding platforms to remove existing glass panels and replace them with new ones. The glass is placed using small cranes positioned on the East Building roof . A suspended platform installed beneath the skylight allows construction workers to facilitate the glass replacement and reinstall various electrical systems safely while also protecting visitors and works of art. Protective enclosures have been placed over large-scale works of art in the Atrium.

To accommodate this work, Alexander Calder’s mobile in the East Building Atrium was removed and protective enclosures were installed around other monumental sculptures in summer 2020. 

Once the glass replacement work is completed, platform deinstallation and art reinstallation will follow.

Improved Accessibility 
June 2019 — fall 2021

Accessible double doors are being installed in the East Building main entrance, and ADA-compliant restrooms have been constructed on the Ground Level near the Study Center entrance. The existing, ADA-compliant family restrooms one floor above, on the Mezzanine, are being updated.

Near the East Building Auditorium, visitors will also find a separate lobby for the accessible elevator, which has been modernized. 


East Building Auditorium Updates
October 2019 — spring 2021  

Separate auditorium and elevator lobbies were created to improve accessibility and visitor experience. The auditorium seats have been refurbished and recovered to their original rust color, and lighting has been improved. For the first time, the public will also be able to access restrooms immediately adjacent to the East Building Auditorium.

While this phase of construction is complete, the National Gallery has suspended all in-person programs as a health and safety precaution due to the COVID-19 pandemic.

Fire and public safety improvements include new emergency exits and stairwell.
