Work is about to start on an $800,000 renovation of the old Butler Furniture building downtown at 640 Main St., which will convert the property to an office building.

The plan is to create three office suites, said Gordon LeBlanc, who bought the building with Tom Adamek, last fall for $530,000. Plans call for one 3,000-square-foot suite and two other suites that will be about 1,200 square feet.

The building, which will be called the Butler Building, will feature amenities such as 14-foot ceilings with skylights. A courtyard will be added to the back of the building.

Rents for the building will be about $20 per square foot.

LeBlanc said he’s talking to a tenant about taking up the largest section of the building. “These will be professional offices for people that want to be downtown,” he said. Potential tenants could include financial, legal, arts or media businesses, LeBlanc said.

The Butler Building is expected to open by September. Chenevert Architects is designing the property. Ben Stalter and Wade Greene of Maestri-Murrell Real Estate are marketing the building.
