Bournemouth Decking & Pagoda Planning Rules

The Golden Rule: The 30cm Height Limit

For the vast majority of houses, you do not need planning permission to build garden decking or a pagoda structure. Under standard Permitted Development rules, your build is completely exempt as long as it meets two simple conditions:

• Keep it Low: The floor height of the deck must not stand more than 30cm (approx 12 inches) off the ground at any point.
• Garden Coverage: The deck, combined with any extensions or outbuildings, must not cover more than 50% of your original garden space.

If your deck is going to be built over a slope (which is common on our sloped Bournemouth chine gardens), we measure the height from the highest point of the slope. If it stays under 30cm, we are completely good to go!

Special Rules for Flats & Maisonettes

Here is a massive trap that a lot of general handymen don't know: **flats and maisonettes do not have Permitted Development rights.**

If your property is a converted Victorian flat in Southbourne or Westbourne, you technically need to submit a planning application to BCP Council for *any* external garden structure, even if the deck is flat on the grass.

I design compact, low-impact decking layouts specifically to blend with Victorian garden boundaries, making it as easy and straightforward as possible for planning officers to approve your application.

Building Inside Bournemouth's Conservation Areas

Bournemouth has 48 strict conservation zones. These exist to preserve the beautiful historic feel of our local suburbs. If your house sits inside a conservation zone, you can still build a gorgeously crafted timber deck or garden pagoda, but there are strict rules around the *materials* and *height*.

Using flashy, plastic-looking composite boards or building huge, eye-catching pagoda frames that stand out above fences can trigger planning complaints from neighbours.

I specialize in designing sympathetic, natural timber frames and choosing high-end, matte-finish composite decking boards that match the surrounding flora, ensuring your build blends beautifully into the local area.

Alfie's Planning Checklist:

• Check Your Boundary: Ensure your deck doesn't look directly into your neighbor's window (privacy rules).
• Tree Protection: If you have protected pine trees near the deck, standard digging can breach tree roots (requires root-friendly raised frames).
• Keep it Reversible: Build using high-quality framing rather than massive permanent brick structures, which avoids a lot of planning scrutiny.
