David Weekley Homes last Friday launched a month long open-house promotion — billed as a record — that invites home seekers across a dozen states including South Carolina to examine scores of model properties.

The Texas builder developed the event, dubbed the World’s Largest Parade of Homes, to commemorate its 40th anniversary. Greater Charleston and Hilton Head Island are among 22 cities taking part in the nationwide cavalcade, which runs through the end of April.

Houston-based David Weekley Homes encourages Lowcountry house hunters to visit “any model or showcase home in Charleston to see current innovations in design and décor trends.”

To mark its “milestone” startup in 1976, the builder plans to donate $5 to Big Brothers Big Sisters of America for each visitor who registers with a sales consultant during the event. Also, registered visitors will be entered for a chance to win one of three prizes: a smart watch, $1,500 appliance package or $2,000 electronics package, David Weekley Homes points out.

The Big Brothers Big Sisters donation ties into efforts of the company’s “charitable and volunteer” CARE program, in which its employees join with homeowners, home buyers, community partners and local nonprofit groups. David Weekley Homes’ “team members” volunteer with local organizations, while The David Weekley Family Foundation contributes more than $100 million to charitable groups in the U.S. and abroad. Those efforts cover 20 years.

Described as the nation’s largest privately-held residential builder, David Weekley Homes says it’s constructed more than 80,000 homes since 1976 that culminated as closed sales.
