Is My Shed Permitted Development? (Curtilage)

[I Know Nothing]

I apologise in advance for not having the exact measurements to hand, but hopefully one of you knowledgeable people will be able to answer my question anyway.

I have a mid terrace house. We recently had a breeze block shed built at the end of the back garden, and is separate from the house. Together with an existing lean-to (built by a previous owner, date unknown) we have used just under 50% of the back garden area, as I understood it to be. It was only later, through the comments of another person, that I realised that my downstairs bathroom was actually an extension built circa the early 1970's. That takes us over 50% of the back garden area.

However, if I take into account the front garden area (actually a concrete area), which is bit larger than the bathroom extension, then I am back under my 50% total curtilage allowance for permitted development.

The new shed is near the boundaries of our next door neighbours, but is less than 3 metres high with a single pitched roof and has an eaves height less than 2.5 metres. My understanding of the rules is that this aspect is OK.

Regarding my curtilage for development purposes, is my understanding correct? Can I take into account the area at the front of my house from my house wall to the highway boundary, and between the two neighbouring properties?

Sorry for rambling. Any replies are appreciated.

50 % of the original house.

You can include the area of the front garden as well.

Thanks for your replies. I guess I should stop worrying now.

Yes as above it's 50% of all the original unbuilt on area, whether it's front back side or whatever. So you're fine.
For that matter you're fine anyway if you wait a few years and don't hear from the council.
And even if you do, you can apply for planning permission. Or if not knock something else down.

The curtilage is not back garden .... unless there is no other front, side, annexed garden.

its restricted to 2.5m maximum height for any part off the building if any part is within 2m off the boundary
"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."

I will have to get my tape measure out again when it's light, but I think I'm still OK.

 

[big-all]

it only matters if someone complains

While taking measurements, you need to check that its <15M sqr floor space too otherwise it has to comply with building control or be substantially non-combustable

Looks like I'm in the clear. 2.4 metres is the highest point on the roof. Total footprint is a little over 11 square metres, while the usable floor area is obviously rather less.

 

[big-all]

remember its from the highest natural point on the ground the shed covers to the top

 

[I Know Nothing]

From highest natural ground to highest point on the roof actually comes out less than 2.4M as the ground slopes a bit. After looking at it closely, though not actually measuring it yet, I am confident that from lowest ground to highest point would still measure less than 2.5M.
