A few months after the "Squatters" began their illegal occupation at the camp, the Royal Army Pay Corps and ATS established a Regimental Pay Office at the camp. Soon this was to become the second largest in the UK for a number of years to follow.
The men and women from both units established a friendly relationship with the local population, and were soon actively involved in many of the social and fund raising events being held in the village.
In line with the UK's changing military commitments around the world, the Regimental Pay Office at Wolverley closed. The military authorities retained ownership of the camp for a number of years to house the families of soldiers serving at other military camps in the area. Eventually the remaining quarters were closed and the site was sold to the county council.
A small number of buildings were used for a short while for emergency accommodation, while others were used for storage purposes. Eventually most of the buildings were demolished creating a park with numerous football and cricket pitches, facilities for horse riding events were established and a separate area set aside for camping and caravans. This new park passed into the ownership of the local District council and was renamed Brown-Westhead Park, after the local family who had owned and occupied Lea Castle for so many years.
