By summer, residents will have four options to weigh when it comes to renovating Marion’s main municipal building.

Next month, the Town House Building Committee will advertise for architects to research options for overhauling the Town House.

Known as a “request for qualifications,” the advertisement is designed to identify an architectural team to prepare feasibility studies to renovate and modernize the Town House.

The 138-year-old building requires extensive repairs and updating to meet building codes.

Building Committee Chair Bob Raymond said the committee would ask for a total of four feasibility studies, which will provide conceptual designs and cost estimates, not full blueprints.

Three of those studies will be focused on renovating just the Town House. The fourth study would incorporate renovations to the Town House, a connection to the Elizabeth Taber Library and building a senior center.

“We’re hoping to advertise in early January and hire an architect soon after. The process should take about a month,” said Raymond. “We want to present the findings to voters at fall Town Meeting in 2015.”

A public hearing in the summer will present the studies to residents.

Raymond said the plans would help inform residents and officials which course to take.

“We are moving forward. The first step is the feasibility studies so we can look at comparative costs for the projects and decide what’s best for the town,” Raymond said.

Raymond said the Town House, which was built in 1890 for Tabor Academy, would not be demolished.

“We heard loud and clear from residents that the committee had to find a way to save the building,” Raymond said. “We decided from the start not to demolish it.”

In 1937, the building was given to the town as part of a land swap with the school, which relocated to its current location on the waterfront.
