BATH | Steuben County officials marked the opening of the new annex building on Morris Street with an open house Thursday.

The three-story building, part of an $8.7 million project that also included a storage facility on Mount Washington, was the result of lengthy planning by the county Legislature’s ad hoc Office Space Committee, headed by Robin Lattimer.

Legislature Chairman Joseph Hauryski said the extra space was necessary, and becoming more so.

“One of the things I was so happy to approve was the addition of the third floor,” he told a group of officials and others at Thursday’s event.

He noted that new state requirements for the court system are expected to take up a large amount of space in the main county office building.

“We’re being almost literally pushed out of the building next door,” Hauryski said.

The next task for the Office Space Committee, he said, will be figuring out how to rearrange the main county building, and what will be moving over to the annex, as well as plans for the Hornell and Corning courthouses.

Officials seemed extremely happy with the results at the new building, thanking the companies involved including LaBella Associates, Werth Construction Services, Edger Enterprises, Schuler-Haas Electric and others.

Lattimer gave a special acknowledgement to county Buildings and Grounds head Eric Rose, who she said has a knack for “paying attention to details that matter.”

Currently located in the new annex building, or in the process of moving in, are the county Records Department, which will keep frequently-requested documents on site in its ground floor office near the building entrance; the Board of Elections along with storage for the county’s voting machines; and Cornell Cooperative Extension of Steuben County.

County officials noted the 30,000-square foot annex building is the county’s first major construction project since the health care facility was built 10 years ago.
