The first phase of TwinLabs, a life sciences complex in Rockville, Md., has been fully pre-leased, with four companies taking the entire 25,000 square feet of space, according to JLL, which is handling leasing for the property.

A joint venture between Bethesda, Md.-based GlenLine Investments and Singerman Real Estate of Chicago is redeveloping two buildings adjacent to the National Institute of Allergy and Infectious Diseases HQ into Class A lab space, after making major capital improvements. The duo acquired the 74,500-square-foot asset in 2020.
