A 4,000-seat concert hall hosting 150 shows a year and new office building are planned in next phases of Charlestown’s 20-acre Hood Park redevelopment, which recently added Cambridge College’s new campus and broke ground on a 177-unit apartment building.

The concert hall would occupy most of the ground floor of a new 775-space parking garage on the Rutherford Avenue property, a former dairy plant redeveloped into office and research space.

Advisers to owner Catamount Management Corp. of Lynnfield told a community meeting the 75,000-square-foot ground floor of the parking garage will include a concert hall run by a national operator and a restaurant, the Charlestown Patriot-Bridge reports.

While the property is two miles from the Wynn Boston Harbor Casino under construction in Everett and a Live Nation concert hall is part of the Hub on Causeway’s development at North Station, the unnamed operator believes the live music market isn’t saturated, Colliers executives said.

A new office building also is planned on vacant land toward the rear of the Hood Park parcel, and negotiations with an anchor tenant for a global headquarters could be completed next spring, Colliers Senior Vice President Mark Rosenshein told the community group.

The existing commercial space in the former dairy plant buildings is 100-percent occupied, with Cambridge College opening its 108,000-square-foot Boston campus in August. The park’s master plan includes 500,000 square feet of additional office buildings, and the property is primed to attract office and lab tenants priced out of Cambridge’s Kendall Square, Colliers executives told Banker & Tradesman in October.

Construction began this fall on a 177-unit apartment building at 480 Rutherford Ave., the property’s first residential project.
