Hi just looking for advice. Our neighbours have built their own decking at the back of their garden and now built a summerhouse on top of that. Their garden is on a slope, which slopes down from our side.
To me, the decking is higher than 30cm to start with but can't measure it. They have now placed a summerhouse on top of the diy decking which comes approx 3 ft higher than the 6ft boundary fence, due to hight of the decking. It's right next to our boundary.
Does this need planning? I know max height of a 'shed' close to boundary is 2.5m but what about on raised decking?
I know the back of our plot is higher, that is the ground level that's always been there, but there's has also been the level of our lower garden level.
The side window of the summerhouse looks into our house and when they are stood on decking they can see right in to our house, feels so invasive. They can see everything we do in our garden when they are on it too.
Also, they have placed it so that any rainwater coming off the roof falls into our garden, which is obviously going to puddle.
I've attached images to try explain what they've done.
Many thanks.
