Melody Adams can’t wait for her new home to be built.

And after this weekend, she won’t have to.

Dozens of contractors, suppliers and builders plan to converge this morning on a concrete foundation at 915 Homewood St., all of them volunteers tasked with accomplishing a first for Lawrence: building a new home in three days.

For free.

“I’ve been living with my mom for going on four years now, actually, and I’m excited about getting back out on my own,” said Adams, a single mother of two. “The sooner the better, actually.”

Adams is buying the donated 1,080-square-foot house, the planned result of a “blitz build” conducted by the Lawrence Home Builders Assn.

Nearly half of the organization’s 260 members are donating their time, materials and money to provide the home through Lawrence Habitat for Humanity. The project is considered part of a national home builders’ effort to put up 400 Habitat homes nationwide in a week, beginning Monday.

Like Adams, the Lawrence workers couldn’t wait for the national project to begin, or to take the allotted seven days to go from floor to roof and fill in the rest in between.

“Overall, this weekend, we’ll have 150 people going through there,” said Kelly Drake, president of the association and of his own company, Mallard Homes. “This is a chance for us all to do what we do for a living and do it for a community purpose. It gives everybody a sense of pride, to be able to work on a project like this.”

The project schedule calls for framing to start at 6 a.m. today, then continue through installation of sod and completion of any minor details by noon Sunday.

The home’s foundation is the only portion of the project that was completed in advance. Organizers even managed to stain the concrete blue – an accommodation for Adams, who didn’t want carpeting or any other flooring.

Drake said that the donated project normally would sell for about $140,000 on the open market.

Adams will get the place for $73,500, through a 20-year, no-interest mortgage, plus her commitment to put 225 hours of “sweat equity” into other Habitat projects, said Jean Lilley, Habitat’s executive director in Lawrence.

“We’re just thrilled,” Lilley said. “We’re just really excited about this partnership. We hope it’s a longtime relationship.”

Adams plans to be on the job site at 8 a.m. today. She and her two children – Autumn, 5, and Avrey, 4 – will observe the professional home builders doing their quality work; the professionals will be on the job as volunteers to make her dream of homeownership a reality.

“I’ve just got to see this happen,” Adams said, as she prepared to drive the ceremonial first nail on the project Thursday night at the site. “They are so confident. It’s their will to do it. It just makes me so happy.”
