A fire that burned a Coastal Club home Sept. 2 caused $750,000 in damage, investigators say.

The origin and cause of the fire remain under investigation, said Michael Chionchio, assistant state fire marshal. Reports at the time of the 8:38 p.m. fire suggested that the fire started on the front porch before moving up to the second floor. Siding on neighboring homes melted from the fire.

No one was at the home in the 35000 block of Acadia Lane near Lewes when firefighters from Lewes, Indian River, Rehoboth Beach and Milton responded to heavy flames. It took firefighters about an hour to bring the fire under control.

Coastal Club, located off Beaver Dam Road west of Lewes, is a large single-family home community under construction. When built out, the subdivision will have 630 units on 360 acres.

There are no reports of injuries at this time. More information will be provided when available.

A GoFundMe has been set up for the owners of the home to help with expenses. To donate, go to https://www.gofundme.com/steve-and-bobbi-wittenberg.
