Clarify 2.5m height planning rule for outbuildings

[kryten22uk]

Been reading the planning portal and got my head in a twist about the wording.

For an outbuilding (ie my shed) it says:
"Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwellinghouse."

Does the 2.5m restriction just apply to the part of the building within 2m of the boundary? For example if a shed starts at 1.5m from boundary at 2m height, and the pitched roof increases the height of the building but doesn't break 2.5m height by the time you get 2m away, but does continue on to a max height of 3m, is that not permitted?

If not it seems odd, as you could have a situation where a building is permitted which is higher at a closer distance than one that is not permitted.

2.5m max regardless of where it occurs.

Thanks, I thought it might be that. It's a bit odd though.

Hmm, so where is the measurement taken from? Is it from the floor of the shed, or the top of the concrete pad (or whatever foundation you've used) ie if you've used those adjustable risers to sit the building, does that count against your height?

It's taken from the highest (pre-existing) ground level immediately adjacent to the structure.

Thanks. So its important to properly plan/dig-in the foundations then rather than slapping on top.

I thought it might just be the height of the structure, but if you built a concrete pad on top of the existing ground, and then added risers and then chunky bearers, your shed could be 50cm high before you start
