WALTHAM, MA—King Street Properties has officially begun construction on 828 Winter St., a speculative laboratory and office building being built adjacent to a property it acquired nearly two years ago for more than $104 million.

The 828 Winter St. building will total 144,910-square feet and will feature laboratory and office space. The project is scheduled for completion in mid-2018. In 2015, Cambridge MA-based King Street Properties and joint Venture partner Carlyle Group of Washington, DC acquired the adjoining 830 Winter St. from Intercontinental Real Estate Corp. of Boston for $104.2 million. The building is fully leased to Histogenics Corp., GlaxoSmithKline and ImmunoGen Inc.
