The Loudoun County fire marshal's office is investigating a fire in Ashburn on Tuesday morning that caused more than $1 million in damage to three homes.

The fire destroyed a house under construction in the 21000 block of Hyde Park Drive in the Regency subdivision, said Mary Maguire, a spokeswoman for Loudoun County fire and rescue services.

The house was being rebuilt after an accidental fire in March that caused $350,000 in damage. The owners were not living there.

The fire spread to the houses on both sides. One of those houses was seriously damaged, displacing a family of six, including four young children, who were placed in temporary housing through the county's After the Fire program and the American Red Cross.

The other house suffered exterior damage, and the siding was burned off one side. No one was injured, but the family of four was displaced and planned to stay with friends while repairs were being made.

Firefighters from Ashburn, Moorefield, Sterling, Fairfax County and Dulles International Airport responded to the fire, which began about 9 a.m. Smoke could be seen from as far away as Herndon.
