RUMFORD – The century-old, beaux arts-styled Hotel Harris was sold Friday afternoon to an unnamed Portland firm.

Aaron Muse of Windham, one of four family members who two years ago bought the ornate structure once known as the Strathglass Building, confirmed the sale to The Harris Hotel LLC, a venture specialist.

He declined to disclose the sale price or name the principal, but did say that the new owner is a solid believer in preserving historic properties.

“We think he’ll continue that work,” Muse said.

Muse, along with his wife, Heidi, and his parents, Jean and Arthur Muse of Rumford, bought the residential hotel in October 2005 from California resident John Roza.

Muse said the family has met its goals of bringing life back into the hotel through renovation of the upper-floor apartments and virtually filling the street-level storefronts.

He said Island Indulgences, a high-end spa, and the Boiler Room at the Harris Restaurant, will remain, as will the apartment residents.

Some changes will likely be made to the residential portion of the three-floor hotel, but Muse does not know what they would be.

The Muse family has retained a long-term lease on the hotel’s basement portion, which had once been the Tap Room. Muse declined to say what that space will become.

“We had a partnership and a number of goals. We’ve actively filled the downstairs, and the cash flow is positive,” he said. “We planned to bring the building back in three phases.”

The family’s company name is Harris Towers LLC.

The hotel was originally built in 1906 by the Rumford Falls Power Co. as an office and retail building. After a fire in 1931 that destroyed everything but the exterior walls, it was rebuilt as a hotel.

The ornate stonework includes huge Corinthian-capped, hand-carved limestone columns. The roof had once boasted 8-foot-high Grecian columns until the 1931 fire.
