The Boston Redevelopment Authority board of directors has unanimously approved the master plan for New Brighton Landing, the first step toward approving the $500 million development project proposed by the New Balance shoe company. 

New Balance has proposed a $500 million project for offices, a hotel and a sports complex along Guest Street in Brighton.

The proposal calls for a 250,000-square-foot world headquarters for New Balance. The sports complex would be up to 345,000 square feet at 77 Guest St. The adjacent vacant lot would
house a 200-meter track and field facility, an NHL-regulation arena, 30,000 square feet of medical office space and other fitness activities.

A hotel of up to 140,000 square feet with about 175 rooms and suites would be located at 180 Guest St., and up to 650,000 square feet of office space would be spread among up to three buildings at 38 to 40 Guest St., as well as up to 65,000 square feet of retail and restaurant space.
