Bethesda, MD, November 4, 2021 – JLL announces today that the first phase of TwinLabs at 5640 Fishers Lane in Rockville, Maryland is fully preleased with four leases totaling more than 25,000 square feet. GlenLine Investments and Singerman Real Estate are redeveloping the former NIH/NIAID complex into highly functional Class A lab space.

“We began marketing the asset earlier this year and immediately saw interest from prospective tenants due to the high quality of the buildout, the speed of delivery and the walkable amenities and Metro line were true differentiators,” noted Danny Sheridan, Managing Director, JLL. “We consistently heard from tenants in the market that this location was preferred and we’re delighted to achieve full occupancy prior to delivery.”

The companies opening in November at TwinLabs – 22nd Century Group, IO Biotech, ResInnova Labs and Liatris – represent growth areas in the Maryland life science cluster including plant biotechnology, anti-cancer immunotherapy, infection prevention, and materials science. Phase Two of the development will deliver five additional pre-built lab suites in Spring 2022 totaling approximately 25,000 square feet and a full floor of 25,000 square feet in lab-ready shell condition at 12441 Parklawn Drive. JLL’s Danny Sheridan and Amanda Davis are immediately working on preleasing of the next phase.

“We are excited to welcome these four vibrant companies to TwinLabs. Their commitments validate our focus on growing clinical stage companies relocating from within Montgomery County or starting up operations in Maryland for the first time,” stated Scott Nudelman, Managing Principal, GlenLine Investments. “Looking forward, we are anticipating similar success with like-minded companies for our second phase.”
