The construction of the new garage required the excavation of three trenches and the reduction of the area within the 'box' by 0.2m-0.25m. Trench 1 measured 6m by 0.55m, Trench 2 was 6.5m by 0.55m and Trench 3 was 6m by 0.55m. Each trench was dug to a depth of 1m, or until the natural geology was reached. Groundworks were undertaken by a mechanical excavator under constant archaeological supervision. The archaeological monitoring works identified no features or deposits of archaeological significance.
