Thorbahn Assoc., a local employee benefits company, is relocating – and doubling its footprint – from approximately 7,000 square feet in Quincy to 14,400 square feet at 141 Longwater Drive in Norwell, also known as Norwell Corporate Center.

The company currently houses approximately 30 full-time employees at 300 Crown Colony Drive in Quincy, and sought a bigger space to accommodate anticipated growth, according to Cindy Cowing of Quincy-based brokerage The Conrad Group. With the lease, 141 Longwater is now fully occupied, Cowing said.

The five-year lease in Norwell is set to begin when Thorbahn moves to the space in January.

Robert Conrad, Paul J. McCourt and Jim McEvoy of The Conrad Group represented both the tenant and the owner, Foxrock Properties, in the transaction.

Foxrock Properties acquired the 120,000-square-foot corporate center last year, and recently renovated the property. Amenities include a full-service, 5,000-square-foot cafeteria, mens’ and ladies’ locker rooms and showers with a complete fitness center, according to a statement.
