Raised Terrace Decking, Borehamwood: engineered-to-load spec for mix of post-war terraces
Raised Terrace Decking in Borehamwood is a specific brief for us — gardens where the deck steps up from a lower lawn or falls away over a slope — engineered elevation, not a ground-level lay. The default local answer isn't a stock catalogue drop: it's engineered post-and-bearer frame in C24, ledger-boarded to the house where suitable, balustrade to 1100mm above finished deck where over 600mm drop. On Borehamwood sites we also spec around limited rear access on the older estates means materials usually have to come through the house, which is where a lot of raised terrace decking jobs quietly fail two years in. Recent work on Theobald Street and Furzehill Road. We orient jobs off Elstree & Borehamwood station. Cardinal Avenue cul-de-sac, four plots. Matched 1.8m closeboard run installed in sequence over five days. Single materials drop, shared waste skip — saved each household ~12% versus solo quotes.
