Stirling Castle

Every truss in the hammer beam roof of Stirling Castle had to be made to slightly different dimensions and pitch because of the bow in the west wall.


Engaged by Historic Scotland, this is one of our largest historic oak frame restoration projects to date. Stirling Castle’s Great Hall is the largest ever built in Scotland and was intended for great celebrations and occasions of state. When the military left the premises in 1964, the work began to restore it as the designers originally intended in 1500.  We provided a new rood screen, doors and external staircase, however the rebuilding of the vast mediaeval roof is what really stands out. The setting out of the roof was inevitably complicated as the west wall of the Hall was so severely out of alignment. The west side of every truss, therefore, had to be set out individually to match the curve in the wall-head; the angle of every joint was also slightly altered as the pitch changed to meet the wall head.
