Poole Decking
Decking in Poole
Last updated: October 2026
DeckWorx is Alfie Jaques, a City & Guilds qualified carpenter who builds composite and timber decking, pergolas and pagodas in Poole, from Sandbanks and Lilliput to Ashley Cross and Broadstone. I'm based in Bournemouth (BH2), and Poole Harbour is the edge of my area: I don't cover the Purbeck side. One garden at a time, no subcontractors, and a free, fixed-price quote in writing.
A new business with one builder. You deal with me from the first visit to the last board.
Poole Harbour
What does living near Poole Harbour mean for a deck?
Salt-laden south-westerly wind does most damage within about a mile of the shore, and it's at its worst from October to March. It greys timber and rusts ordinary fixings until they lose their grip … known as nail sickness. Sandbanks, Lilliput and the harbour edge take the brunt.
Some harbourside gardens also sit low. Poole's coastal strategy (written in 2014) put around 573 central Poole properties at high risk of tidal flooding. For a low garden near the water, I plan for wet ground from the start.
Sewerage here is split between Wessex Water and Southern Water street by street, so if a deck needs a drainage run I check which company covers your address.
The Rules
Do I need planning permission for decking in Poole?
Often not, for a house. For a house, the Planning Portal says decking needs no application when it is no more than 30cm above the ground, none of it is in front of the main front wall, and together with other extensions and outbuildings it covers no more than half the garden.
Poole has several of BCP Council's conservation areas, including Sandbanks, Branksome Park and Chine Gardens, Canford Cliffs Village, Ashley Cross, Poole Park, and Ridgeway and Broadstone Park. In those, decking at the side of the house needs permission. Flats and maisonettes, including the split-up villas around Poole Park, don't get decking permitted development rights at all.
Branksome Park also has an Article 4 direction covering walls, fences and enclosures along the road. If a raised deck needs a screen facing the street, that needs permission there.
How I Build
How do I build a deck that copes with Poole ground and salt air?
The ground under Poole isn't one thing. The British Geological Survey maps Branksome Sand in an arc from Ferndown through Parley to Branksome, with clay layers in between. Loose sand can let a ground screw lose its grip; clay swells when it's wet and shrinks when it's dry. So I dig a trial hole before I choose the footing.
Every post in the soil is Use Class 4 treated, meant for permanent ground contact, every fixing near the water is marine-grade stainless, and I cut the joints rather than relying on brackets.
Composite decking makes a lot of sense near the harbour. In my words: it's better at draining and doesn't absorb as much water, which means it won't expand or rot. My composite vs timber guide sets the two side by side.
Clay is its own subject, so I've written a separate guide to building decking on clay soil in Poole.
Decking is one part of what I build. See all my decking, pergola and pagoda services across Bournemouth, Poole and Christchurch.

Around Poole
Sandbanks, Branksome Park and Poole Park
Three parts of Poole, three different starting points.
Sandbanks and Lilliput
Salt air and the waterline: Sandbanks is a conservation area in its own right and sits right on the water. Expect marine-grade stainless fixings, Use Class 4 posts and, often, composite boards.
Branksome Park
Street frontages and chines: Branksome Park and Chine Gardens is a conservation area, and its Article 4 direction covers enclosures along the road. I check what faces the street before I design a raised deck or screen.
Poole Park and Ashley Cross
Converted villas: Both are conservation areas, and some of the larger houses around Poole Park are now flats. A flat's garden gets no permitted development rights for decking, so I flag that before quoting.

Got Questions?
Poole Decking Questions
Do you build decking in Sandbanks?
Yes. Sandbanks is in my area and is one of BCP Council's conservation areas, so the rules for the side of the house are tighter. Near the water I use marine-grade stainless fixings and Use Class 4 treated posts.
Is composite decking better for a garden near Poole Harbour?
Often, yes. Composite drains better and doesn't absorb as much water, so it won't expand or rot, and it doesn't need the regular treating timber does. Timber still works if you want a natural look and don't mind the upkeep.
Do you cover the Purbeck side of Poole Harbour?
No. The harbour is the edge of my area, so I don't build in Studland, Swanage or the rest of Purbeck. Everywhere else within about 10 miles of Bournemouth is covered.
Will you be on site the whole time?
Yes. I'm a sole trader and I work on one garden at a time. You deal with me from the quote to the last board, and I clear up as I go.
