When first built it consisted of just the main meeting room and was surrounded
by trees and open fields. Over the years a wooden kitchen annexe was added to
the front and a workshop was built alongside.
In 1984 an arson attack destroyed the wooden annexe and caused damage to the
rest of the building. This prompted a rebuilding programme which saw a new roof
over the main room, a permanent extension at the front, housing a toilet and
kitchen, and the conversion of the side workshop into a new model railway room.
