Timber decking, raised or at ground level
In short We build timber decking in Saltash, Plymouth and across Cornwall and Devon, including raised decks with balustrades and steps. This page explains when a raised deck suits a sloping garden and what to check before building one.
Which deck
Raised or ground level?
The garden usually decides. A flat plot suits a low deck; a slope or a high back door suits a raised one.
Ground-level deck
Sits just above the ground, on a level frame. A simple way to get a dry, flat seating area on lawn or uneven ground.
- No balustrade needed at low height
- Usually no planning needed (under 30 cm)
- Works beside a patio or lawn
Raised deck
Built up on posts to meet a back door or make a sloping garden usable. The deck becomes a level room outside.
- Balustrade and steps built to match
- Planning permission needed above 30 cm
- Useful space underneath for storage
Before you build
Five things to check.
Planning limits first, then the practical ones. Checked on the Planning Portal on 22 October 2026.
- Height. More than 30 cm above the ground needs planning permission.
- Size. Decks, extensions and outbuildings together can cover no more than half the garden without permission.
- Position. A deck in front of the house needs permission.
- Listed buildings. No decking without permission inside the grounds of a listed building.
- Privacy. A raised deck looks over the fence. Think about where the neighbours' windows are.
Raised timber decking area with bespoke balustrade.
Does a raised deck need a balustrade?
A deck high enough for a fall to matter should have one, and it makes the edge feel safe for children and visitors. On one recent garden we built a raised timber deck with a bespoke balustrade.
Can a deck have steps down to the lawn?
Yes. Steps are built to the same timber and finish as the deck, sized so they are comfortable to walk.
How do I look after timber decking?
Sweep it, keep it clear of leaves so it dries out, and clean it before the slippery season. Treating or oiling it every so often keeps the timber looking good.
Do I need planning permission for decking?
Not if it is no more than 30 cm above the ground, covers no more than half the garden with other buildings, and is not in front of the house. Listed buildings always need permission.
