Raised Terrace Decking in Stevenage — Built for how the structure performs under real use, not a showroom drawing
Raised Terrace Decking in Stevenage 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 Stevenage sites we also spec around shared-with-neighbour fence runs are the norm — quotes need to cover boundary checks first, which is where a lot of raised terrace decking jobs quietly fail two years in. Recent work on Walkern Road and Bedwell Crescent. We orient jobs off Fairlands Valley Park. Shephall Way 3-way rear corner. Closeboard with stepped gravel boards; corner post agreed jointly with two neighbours. Ended a long-running disagreement about ownership of the leaning panel.

Raised Terrace Decking FAQs — Stevenage
What post spacing do you use on a raised structure?
