Developers have submitted site plans for what could be some of the last single-family residential lots, for now at least, in Autumn Hall, a master planned mixed-use development on Eastwood Road that traces its roots to a Trask family land purchase more than a half-century ago.

The 21 new lots in plans recently submitted to the city of Wilmington would be the last single-family home sites for what’s been approved by the city in terms of housing in the development, said Blake Frazier, vice president of sales for Fonville Morisey Barefoot, who is in charge of sales for Autumn Hall homes.

“We’re down to fewer than eight lots that we have left right now,” Frazier said Tuesday about the home sites there that currently exist.

If city officials sign off on the new lots (the site plans are up for a review before the city of Wilmington’s Technical Review Committee on April 20), Autumn Hall will have at least 200 homes when construction is complete.

“We’re selling about one or two a week right now,” Frazier said. “It’s an amazing pace.”

Some of the land in the more than 200-acre development in the 1200 block of Eastwood Road is expected to be home to future commercial development. A commercial building called Dungannon Village, which so far includes professional offices and a coffee café, is under construction and expected to be complete by next month.

The pediatric specialty clinics at New Hanover Regional Medical Center are moving to the NHRMC office building at Autumn Hall this year. The community also includes apartments, Headwaters at Autumn Hall and Carolina Bay at Autumn Hall, a continuing care retirement community.

Single-family homes there start at around $600,000, with several recent sales in the $800,000 range, Frazier said. Builders chosen by buyers to construct their homes adhere to the community’s Cape Fear Heritage Architecture standards, he said.

In addition to the strength of the area’s real estate market in general, “I think it’s the quality of the product, the uniqueness of the product, the ability to buy your own site and choose your own builder and then the location, location, location,” Frazier said, that account for Autumn Hall’s appeal.

That appeal has brought about a construction boom in the neighborhood, he said.

“There’s probably at any given time 10 to 12 half-million-dollar-and-up homes going up at one time. Just the impact of what that brings [to the local economy] is pretty amazing,” Frazier said. “It’s been that way for probably the last 12 to 18 months at least.”
