Impressive progress is being made at Boston Landing, a transformative multi-phased mixed-use development project in Boston's Allston neighborhood. New Balance's recently-opened headquarters building has a striking presence on both Guest Street, the Boston Landing development's main artery, and the parallel Massachusetts Turnpike, with sweeping curves and an overall distinctive design. New Balance's new headquarters opened for business in September 2015. Next door, an under-construction ice rink and 10-story office building are nearing completion. The ice rink will serve as the Boston Bruins' official practice facility.


On our recent visit, the construction team was hard at work putting finishing touches on the ice rink and office building, both of which are expected to be complete by fall 2016. Take a look at our new construction photographs posted above. More project information, including the full Boston Landing development plan, is posted below.
