You could call it a real godsend.

LoAnne Spaulding knew the former Dutch Reform church on Route 1 in Belfast would make a fabulous house. A restoration veteran with impeccable taste, Spaulding drove by the property on her way to church every Sunday, waiting for it to go up for sale.

“One Sunday it had gone up for sale,” she said. When she went for a tour, she says, “I fell in love. I literally fell in love.”

That was 1993. The Spauldings already had restored a sea captain’s house in Searsport, and they recognized that the church had good bones, despite a few aesthetic concerns.

“I saw what it could be,” Spaulding said. “I’ve always been drawn to interesting architecture. Buildings that weren’t particularly meant to be houses were always sort of interesting to me, a schoolhouse or a church.”

Spaulding’s vision is the subject of Sunday’s episode of “reZONED” on HGTV. The series focuses on the transformation of public buildings into private homes. In addition to the Spaulding home, the show will feature the renovation of a round barn in Iowa into a three-story family home; a furniture store-turned-mansion in downtown Muncie, Indiana; and a Kentucky stable and carriage house that an architect turned into a gracious home.

During the six-year renovation of the church, Loanne had a transformation of her own: She has since started her own interior design firm called, appropriately enough, Reformations.

“I think if you’re a preservationist at heart, anything goes,” she said.
