This is a non-issue for you, so don't worry.
Planning permission for our gazebos is not usually required, even in defined Areas of Outstanding Natural Beauty. A White Pavilion Garden Gazebo is viewed as being similar to a greenhouse or garden shed. If you are unsure and would like some advice contact us on, 01653 695 285.
The photo shows our Tuscany 3m x 3m x 2.80m gazebo in Gerrards Cross, installed on top of a 2 step timber deck and located within 2 metres of the boundary.
Because of its location, within 2 metres of a boundary, it was outside the automatically approved 'permitted development' rules. i.e. over the 2.50 metre height limit and closer than 2 metres of the boundary. Planners visited this customer, after a 'moan' from a neighbour. They liked it and gave their approval.
Check out our website photos, and you will see dozens of our customers place their gazebo within 2 metres of the boundary. They did not apply for planning approval.
Our customers take the view that if it ever becomes a planning issue, they will apply retrospectively, and get it.
A word of caution. If you ask your neighbour for their approval, you risk getting the wrong answer.
Siting your gazebo, with the nearest leg, 2 metres or more from the boundary is within your automatically approved 'permitted development rules', so does not require any planning application.
Over the last 11 years and nearly 2,000 sales, we have never had a planning refusal because the gazebo is sited too close to a boundary. So in our customers experience the planners always give approval, as you can see with this example above.
The planners are not concerned with the minutia, i.e. 30cm [12"] too tall.
