A 15,000-square-foot, two-story building at 961 Commonwealth Ave. in Boston has been sold to New York-based Shire Real Estate for $4.3 million.

Grubb & Ellis Co. Senior Vice President Bradford Spencer facilitated the sale from 961 Commonwealth Avenue Realty Trust. The building, which consists of retail and R&D/lab space, is located within Boston University’s John Hancock Student Village. The building at 961 Commonwealth Ave. has two long-term tenants — Qdoba Mexican Grill, which occupies street-facing space totaling 3,000 square feet, and Brigham & Women’s Hospital, which occupies the 11,200-square-foot administrative, engineering and lab space in the rear.

"The stability of the property combined with a highly desirable location allowed us to generate numerous offers from well-known buyers," Spencer said. "Through a comprehensive marketing process, we were able to help ownership achieve its financial objectives."
