A stately brick building that has been a grammar school, a music conservatory and a medical marijuana grow house is headed back to the drawing board.

The former Peirce Elementary School building at 24 Church St. recently was listed with The Masiello Group for $395,000, according to agent Penney Read.

Owner Mark Crockett, of Midcoast Development LLC, bought the building and ¾-acre lot at the corner of Church and Elm streets in 2013 for $220,000 at a public auction. It is currently assessed by the city at $360,000.

Crockett, a medical marijuana caregiver, confirmed one of Belfast's best-known secrets, that the former elementary school was the site of a caregiver growing operation during his ownership.

However, he was quick to say the grow house was a temporary use, based somewhat on the real estate market at the time.

"My ultimate goal was to do what was best for the property," Crockett said. "Now that the market's improved, and the condition (of the building) is improved, the best use for that property is not for a caregiver, but something better for the community."

Crockett, who has been fighting a recent Rockland moratorium on marijuana-related businesses that left his own application for a Main Street business in limbo, said he is hoping to see the former Peirce School used for something "boring," like condominiums or professional offices. To that end he is offering to share with the eventual buyer a set of plans he had drawn up for converting the building to condos.

"It will lend itself really well to that, with the big windows and high ceilings," he said.

The Peirce School was built in 1915 and operated as an elementary school until 2003, when School Administrative District 34 consolidated students from three small elementary schools in the newly constructed Capt. Albert Stevens School. Four years later, the city sold the building to William Ryan, who won over the City Council with his proposal to start the Belfast Academy of Music.

The fledgling academy operated for several years, offering private music lessons and concerts primarily of classical music, but it never took off. Ryan lost the building by foreclosure to mortgage holder James McClelland, who sold it at auction in 2013, where it was picked up by Crockett.

Crockett said the building has been improved in the last five years, with repairs to the plaster ceilings and an upgrade to the electrical service. Otherwise, he said, there's little evidence of its recent use.

"It's exactly like it was when I bought it," he said. "Chalkboards still on the walls."
