The earliest deeds for the house date back to 1709 when it consisted of 2 small dwellings. Shortly after 1822, the houses were converted into one dwelling when The Forest was the home of the Herberts, the owners of Dolforgan estate. During the mid 19th century to house was owned by the Walton family before becoming the property of the Willans family who, in 1912, carried our major improvements.
An article in the Montgomeryshire Express of 1914 detailed the improvements. "The out offices comprised of a six-roomed gardener’s cottage, stable for four horses, cow house, pig styes, kennels, wash house, boiler house, two garages (one with pit), harness room, tool houses, granary, hay loft, store rooms, potting shed, fruit room, and all the sanitary essentials."
The Forest was sold in 1922 and passed through various owners over the years who used it as a family home. The outbuildings were variously used for a pig farm and later for a poultry farm when 3 large new barns were added.
