The community was developed by the Poretsky Building Group, which at the time, was a well known and award winning Washington D.C. area builder. Construction started in 1987 and was completed in 1989. There are two models, the Ascot and the Beech, which are pictured below.
The Mains is part of the Penbrooke Association which also includes the Gables, Bentley Place, Luxberrry, and Timberlawn. These communities share the costs to maintain and operate the swimming pools, tennis courts and play area.
