Nearly 31,000 square feet of new leases and renewals have been completed over the past six months at a major office building in Rocky Hill.
With the lease activity, the 110,000-square-foot Corporate Ridge office building at 55 Capital Blvd., has increased its occupancy rate to 75%, according to building owner KS Partners and its leasing agent CBRE.
The largest deal was with engineering firm HNTB, which expanded and extended its lease to more than 23,000 square feet, more than doubling its space. There were also two new leases: office-furniture dealer John Watts & Associates now occupies 4,200 square feet in the building after relocating from downtown Hartford, and the Credit Union League of Connecticut signed for 3,000 square feet.
The Class A office building at 55 Capital Blvd., which was erected in 1988, anchors the entrance to Corporate Ridge, a 230-acre business park located just off Interstate 91. The building includes recently updated lobbies and common area spaces, along with a new tenant lounge/bistro on the first floor, according to CBRE, which was hired by KS Partners as the exclusive leasing agent for the building in 2024.
CBRE said it has subsequently been hired as the exclusive leasing agent for KS’ sister building at 175 Capital Blvd.
