Trillium Brewing Co. plans to acquire a 135,000-square-foot building at the former Reebok campus in Canton for a large beer hall and events facility, adding a new destination in the single-use office park on Royall Street.

Spear Street Capital bought the 65-acre corporate campus overlooking Route 128 for $88 million in March. It’s decided on a multitenant leasing strategy, said Laura Dunn, a vice president at Spear Street Capital.

Following a six-month branding study, Spear Street is marketing the property as “The Block” with an eye toward attracting up to four tenants to fill the 518,000-square-foot office building. CBRE is the leasing agent.

“The opportunity is to lease this extraordinary real estate that’s incredibly high quality and to show how that can be reimagined and multitenanted,” Dunn said this week at a real estate forum sponsored by the Commercial Brokers Association.

In an imminent transaction, Trillium will acquire 100 Royall St., a former Instron Corp. building most recently occupied by Reebok, Dunn said. The 2-story light manufacturing building was completed in 1978, according to assessors’ records.

Trillium, an award-winning craft brewer, started out in Boston’s Fort Point and added a 16,000-square-foot brewery, retail shop and taproom at 110 Shawmut Road in Canton in 2016. It opened a new 3-story restaurant and brewery at 50 Thomson Place in Fort Point in October. The company also is planning to open a farmhouse brewery in North Stonington, Connecticut. Company executives could not be reached for comment.

Reebok left the custom-designed Canton headquarters last fall as it opened its new global headquarters at Jamestown’s Innovation and Design Building in South Boston.

The arrival of Trillium will add some life to the Royall Street park on nights and weekends, after office workers from neighboring companies such as Dunkin’ Brands and Boston Mutual Life Insurance head home. Trillium plans to sponsor corporate events and festivals at the property, Dunn said.
