Property Overview
The Hayden Research Campus, consisting of 45,55, 65, and 75 Hayden Avenue, is a 610,000 square foot office and lab campus ideally located on over 37 acres of land in Lexington, MA. The campus is in a prime location just off Route 2 and Route 128, and in the heart of a trio of greater Boston’s strongest lab and office markets, Cambridge, Waltham, and Lexington. It served as the world headquarters for Cubist Pharmaceuticals until it was acquired by Merck in 2015. King Street purchased the Hayden Research Campus in November of 2016 from Merck.
65 Hayden is a state-of-the-art laboratory building that was substantially renovated and expanded in 2010. The building was 37% leased at acquisition. King Street completed a comprehensive capital improvement plan to multi-tenant the building, upgrade building systems, and add modern tenant amenities, all of which make 65 Hayden Avenue the premier suburban destination for lab tenants.
45-55 Hayden is a Class A office building that is 100% leased on a long-term basis. Shire Pharmaceuticals, which owns/leases over 1,400,000 square feet in the immediate vicinity, has leased the property on a long-term basis.
75 Hayden is a 213,000 SF newly developed, state of the art laboratory facility purpose-built for research tenants. The facility is 100% leased to four tenants.
