Raised Terrace Decking: The Sector-Wide Brief



A raised terrace is a structural build, not a ground-level lay. Posts, bearers and balustrade all get sized for the actual elevation and span involved, and building regulations start to apply once the drop passes 600mm.
We build these across gardens that step up from a lower lawn, fall away over a slope, or need a walkway out to a garden studio — the engineering comes first, the finish second.
Raised Terrace Decking by town
Pick your town for local council rules, postcodes and property context.
The structure behind the finish
An engineered post-and-bearer frame in C24, ledger-boarded to the house where suitable, with balustrade built to 1100mm above the finished deck wherever the drop exceeds 600mm.
- Yellow balau hardwood on treated softwood frame
- Capped composite for zero-maintenance elevated decks
- Ipe for premium raised terraces where a 25-year life matters
Where building regulations apply
Approved Document K applies once the fall exceeds 600mm — we build to a compliant handrail height as standard rather than treating it as optional, and elevations over 3m or attached to habitable rooms above ground floor need full structural sign-off rather than a joinery quote.
Integrated detail at frame stage
Drainage runs and any low-level LED lighting are sorted at the frame-building stage, not chased into a finished deck afterwards — that's the difference between a tidy job and a visible retrofit.
Raised Terrace Decking — frequently asked
When does a raised deck need a handrail?
Once the drop from the deck exceeds 600mm, building regulations require a compliant handrail — we build to that as standard.
How high can I go before I need building-regs sign-off?
Elevations over roughly 3m, or decks attached to habitable rooms above ground floor, need full structural sign-off rather than a standard joinery quote.
Composite or hardwood for a raised terrace?
Both work — capped composite for zero maintenance, hardwood such as yellow balau or ipe where a natural finish and long service life matter more.
Can the deck attach to the house wall?
Yes, where suitable, via a properly flashed ledger board — we check the wall construction first.
What post spacing do you use on a raised structure?
It depends on span and load, calculated per job rather than a fixed default — that's the difference between a raised deck and a ground-level lay.
