Raised Terrace Decking in Finchley (N3)
Raised terrace decking in Finchley is one of our regular briefs — gardens where the deck steps up from a lower lawn or falls away over a slope — engineered elevation, not a ground-level lay. On edwardian terraces in church end with mid to large gardens; mature trees and London clay are the recurring constraints, the failure mode we see most often is the one we design out first. Recent work on Fallow Court Avenue and East End Road. We orient jobs off Church End library. Long Lane front picket and side gate. Painted picket with bespoke matching side gate. Matched the existing four-plot street line.
