driving discovery

a modern engine
for innovation

WEL provides the chassis and infrastructure of a high-performance research building along with a finely appointed interior of spaces to support a mission-driven community. Designed specifically for those leading discovery, pushing innovation, and creating a brighter tomorrow – all within easy reach of New York's greater life science ecosystem.

honoring the past

First built in the 1920s as an automotive showroom and repair facility for the Chrysler Corporation, 125 West End Avenue is being redeveloped as West End Labs (WEL) — a state-of-the-art research and development hub, purpose-built for a new generation of scientific discoveries and achievements.

building the future

WEL embraces its industrial roots by retaining integral components of its existing structure that will now support and parallel the needs of the life science industry. Once designed to move and repair cars, the reinforced concrete structure and original automotive helix will now move ideas through a new physical and cultural framework while reimagining the look, feel, and systems needed for cutting edge R&D.

At WEL, what was old is new again.
