The majority of the homes in CountrySide were built by the homebuilder Pulte Homes, and are of the colonial architectural style.
Potomac Green is located near Ashburn and was developed by Pulte Homes, marketing it as Del Webb community.
Pulte has subsidiaries that include Del Webb, which builds retirement communities, and Palm Beach Gardens-based Divosta Homes, a pioneer in the mass-market construction of cast concrete houses.
