Huntington Avenue apartment tower would extend Boston’s spine past Mass. Ave.

The Boston Planning & Development Agency signed off December 14 on a proposal that will extend Boston’s famed spine of spindly buildings.

A trio of developers plans to build a 32-story, 362-foot apartment tower on Huntington Avenue a little west of Massachusetts Avenue, where the spine peters out.

The height and scope—the tower is due to have 426 apartments—make economic sense given a particular feature of the project, according to the builders.

The project includes a refurbished and expanded Huntington Theatre inside and alongside the tower, according to the Globe’s Tim Logan. The theater company, which will also contribute to the refurbishment, will own its building and get a low-cost, 100-year lease for much of the tower’s lowest two floors.

Construction on the whole shebang could start in 2018.
