At the 220-home Serenbe project near Atlanta’s airport, the cachet of local produce has been added to retiree-friendly businesses, including galleries, a bed-and-breakfast and three restaurants. Steve Nygren, an Atlanta restaurant impresario, started the project on his 900-acre farm.

“We preserved forest and pasture, and there were 20 acres left for an organic farm, and we also have a large wildflower meadow,” Mr. Nygren said. “We’ve set up the design so 90 percent of the houses back up to one of those natural amenities. We are selling our lots at a premium that’s probably three times what the raw lot is.”

Mr. Nygren has focused Serenbe’s second phase on “edible landscaping,” he said. “At street corners there are blueberry bushes, fig bushes, peach trees and spotted apple trees.”

And in more rural areas, developers are buying big tracts of ranchland and selling small lots to buyers. David Hamilton, a principal in Qroe Farm Preservation Development, is pursuing this approach at the sprawling Bundoran Farm subdivision outside Charlottesville, Va. “We go through a mapping process to see functional agricultural units, if they are good for apples or cattle or whatever, then see where they go together.

Qroe (pronounced “crow”) leases some of the land to cattle ranchers and orchard managers. A buyer of a home site hires a builder from a developer-approved list. Qroe is marketing lots of under four acres for less than $400,000, Mr. Hamilton said. “You’re buying two acres but access to 2,000 acres,” he said.

Grady Lewis, a Virginia native who closed on his 2.67-acre lot in 2007 and moved into his 1,800-square-foot house at Bundoran with his wife, Diane, this spring, responded to Qroe’s idea of preserving “rural quality.”

When all the house lots have been sold, the rental income from the farmers, which currently goes to the developer, will go to the homeowners’ association. “Beyond it being great to see 300 head of Angus scattered across the acres,” Mr. Lewis said, “it’s a cash-flow issue.”
