It has a population of just under 150. The majority of the housing stock is detached with generous size plots. There is a mixture of late 19th century estate and farm-workers' homes, plus a post-war ribbon development of larger homes along Brimpton Lane, The Byway and Kingsclere Road.
The commons are flat land about 100 metres above sea level and the highest land between the watercourses to north and south. They are the remains of a marine sedimentation laid down in Tertiary times, subsequently raised by the uplift of the land in later geological times. A layer of clay between 0.5 and 1.0 metres thick provided an acidic topsoil on which the native vegetation was pine, heather and associated species. Below this was a bed of gravel, up to 3 metres deep. All of the exploitable gravel in Brimpton Common has now been extracted and the land has been restored to a mixture of agricultural land and fishing lake.
Business
There are no shops in Brimpton Common, but the local employment includes: AWE Blacknest, a major centre for international seismological research; Lakeside Garden Centre, The PineapplePublic House plus a few small businesses surrounding AWE Blacknest. The Pineapple is 900 years old and it is mentioned in the Domesday Book. It was frequently used by shepherds and drovers as an overnight stop. The name is derived from the pine forest that once surrounded the area, a pine apple being a local name for a pine cone. The furniture inside the pub is noteworthy. It was made by a local craftsman using only a chainsaw and chisel and carved from the last of the English elm. For many years up to the 1990s its local worthies included “Cowboy Roy” and Gerry the Poacher, and their portraits once hung on either side of the fireplace in the public bar.
