Northeastern University reports it's bought Horticulture Hall on the side of Massachusetts Avenue across from the bulk of its campus.
Suffolk County Registry of Deeds records show the purchase price was $22 million.
Northeastern already has offices in Belvidere Place, the Christian Science Center building that looks like the Christian Science office tower on its side on Huntington Avenue.
In the short run, Northeastern will use space in the building - including space Boston Magazine will be vacating this summer - for offices. In the long term, the school says it's working with the city on "a plan that takes advantage of the rich history and architecture of the building to program it with all the exciting things that happen at Northeastern."
Northeastern's moves across Mass. Ave. bring it that much closer to Berklee College of Music and could eventually set up another spot in Boston where two schools run right up to each other. Harvard and BU already meet in Allston, along the former train yard that Harvard now owns, while Suffolk University and Emerson College meet on Washington Street in Downtown Crossing.
