Raised Terrace Decking in Barnet (EN5)
If you're weighing raised terrace decking for a property in Barnet, the first thing that matters is how the structure performs under real use, not a showroom drawing — not the material choice. Once that's settled, yellow balau hardwood on treated softwood frame is where most of our raised terrace decking work in EN5 lands, with capped composite for zero-maintenance elevated decks as a considered alternative. Recent work on Hadley Green Road and Kings Road. We orient jobs off Hadley Green. Hadley Green frontage replacement. Painted softwood picket on oak posts to match conservation guidance. Passed informal council eye-check; matched four neighbouring plots.

How we build raised terrace decking in Barnet
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 Barnet jobs we adjust for shared-boundary disputes are common on the older terraced streets, so neat post lines and clear ownership marks matter.
Property mix locally: Victorian terraces, post-war semis and a band of larger Edwardian villas around Hadley Green. Typical gardens: narrow rear gardens with mature trees and London clay underfoot. Postcodes we regularly service: EN5, N20.
Approved Document K applies where the fall exceeds 600mm — we build to a handrail height that clears it.
Why this spec, for gardens where the deck steps up from a lower lawn or falls away over a slope — engineered elevation, not a ground-level lay
- structural posts sized for the elevation and span — not a chippy's guess
- handrails and balustrade built to building-regs height where the drop demands it, without looking like a scaffold
- integrated LED and drainage runs sorted at frame stage, not chased in later
Where raised terrace decking isn't the right answer
- — elevations over 3m or attached to habitable rooms above ground floor — needs a full structural sign-off, not a joinery quote
- — gardens where the sensible answer is landscaping the level, not raising a deck over the fall
Typical raised terrace decking briefs in Barnet
- → raised hardwood terrace at first-floor kitchen-door level over a sloped lawn, with integrated steps
- → long thin raised walkway to a garden studio with balustrade and low-level LED trim
