  1 x Hornbeam (applicants ref. T1) - Crown thin by 20%. Raise Crown an additional 0.5m from ground level making sure screening of shed is maintained. Reduce selected areas of the upper crown by pruning in the extraneous growth by approx 1m and lightly reduce any extraneous lateral growth to balance the light height reduction works. Do not reduce the whole tree as this would only encourage re-growth and change its natural shape. Remove dead wood. Standing in T22 of Tree Preservation Order.
