The Bloomington resident, who currently lives with her husband, Clarence, and two children, Theresa and Bailey, in a two-bedroom apartment on Third Street, joined about 20 other volunteers to construct Habitat for Humanity of Monroe County’s latest family dwelling. By Friday afternoon, four walls stood in a grassy area next to the DeVault Alumni Center on 17th Street.

“I can’t believe this is going to be ours,” she said, adjusting her yellow hardhat. “When I told the kids we were moving into a three-bedroom house, they asked, ‘But Mom, what are we going to do with the third room?’ They’re so used to sharing!”

Indiana University volunteers, partnering with Whirlpool Corp. and the Kelley School of Business, plan to finish construction of the 1,100-square-foot house by Oct. 8.

Then they’ll transport it to Maple Heights — a neighborhood, already populated by other Habitat homeowners, northwest of downtown.

“We already know most of our neighbors, because we’ve helped build their homes,” said Knapp, who’s been volunteering for the organization since last October. “It’s a close community.”

Knapp’s family was selected for new home ownership based on need, current living conditions and their ability to eventually pay off the $65,000 interest-free mortgage. To be eligible, they completed 250 hours of volunteer work dubbed “sweat equity.”

“It’s exciting to know we can hang a painting or paint a bedroom a color,” she said. “We couldn’t do that before.”

Kerry Thomson, executive director of Habitat for Humanity Monroe County, estimates she’s helped build nearly 100 houses in Bloomington. The program brings the community together, she said.
