Re: Bulletproof shed

My 40m2 was erected under permitted development no planning required but required building control approval as it was over 30m2. Are you referring to the eaves height which is 2.5m and 4m to an apex?

From Google -

Height: The maximum height must not exceed 4 metres for a dual-pitched roof, or 3 metres for any other roof (e.g., flat or pent).

Eaves Height: The maximum eaves height (where the wall meets the roof) must be no more than 2.5 metres.

Boundary Rule: If the shed is within 2 metres of a boundary (like a fence or wall), the total height of the building cannot exceed 2.5 metres.

Ground Coverage: The shed, along with any other outbuildings (greenhouses, garages), must not cover more than 50% of the total land around the original house.

Floor Area: A floor area of up to 15 square metres (sqm) is generally safe, while up to 30 sqm may fall under permitted development, provided other conditions are met. Building regs also applies for floor areas in excess of 15 square metres.

I *think* it must also be classed as 'temporary' - i.e. no dug foundations

Once again, the height of the shed doesn't trigger this. Why would a shed company sell things which are difficult to erect, it's in their interests to make it as easy as possible for customers.

This is all interesting to know, but doesn't affect the shed I'm enquiring about. It was checked before the shed was ordered.

I'm not sure I've ever seen a wooden shed with dug foundations. But there's a first time for anything I suppose.

Well my woodshed has a 6" thick concrete base sunk in the surrounding wotsit with brick footings to about a foot high, to get the timber clear of the rot zone

'temporary' it ain't. :-)

The base and the footings (which don't require planning permission) might not be classed as temporary, but the shed on top of them is.

That would apply to my whole house then :-)

purely wooden on top of concrete and brick footings
