Definition of roof types for garden shed within the exempt planning rules

Calahonda52

White is A roof, ridge can be 4m

Red is lean-to: max height 3 m

Cyan is a bit of both: what limit applies?

Context existing 17m long shed was granted retention, is lean to, not shown with max height 2.8m

I want to raise it a bit, and reverse and increase the slope to 10 degrees.

The red will give max height of 3.8.

Thanks as always

My reading of the exemptions is 3m max height applies to your proposal Colm. However it could be argued that if it is a tiled or slated roof then as it is pitched the 4m height would apply. But I doubt that it is tiled or slated as you intend to increase the pitch to 10 degrees so its obviously finished with felt or corrugated sheeting.

The wording in the exemptions is "The height of any such structure shall not exceed, in the case of a building with a tiled or slated pitched roof, 4 metres or, in any other case, 3 metres"

So back to this.

This is 2.4m on the left and 2.5m on the right.

Want to increase it to an A roof with apex at 3.9m

This was a dog kennels and is 17.5m . by 4.5m external foot print, retention was granted prior to the sale.

So will I need planning to change the profile if its below 4m due to the size?

Thanks as always

With the exemptions you have to satisfy the conditions so once you exceed the floor area threshold of 40m2 no other conditions are operable. Basically the exemptions are gone. Having got retention is a bonus but you would need permission to increase the ridge height imo. Here in Donegal small changes can be dealt with by way of correspondence and a small fee so maybe have a word with the local planners to get their opinion.

At that size it won't ever be exempt. But for the sake of clarification;

The exemptions have nothing to so with the shape of a roof. The red line is a mono-pitch roof, and there is nothing (afaik) that says you can't do that.

The shape of the roof and it's height is stated in the exemptions at class 3 (5). There is a distinct difference between a pitched roof and a mono-pitch roof.

The exemption only specifies tiled/slated pitched roof. There is definitely a difference between a pitched gable roof and a mono-pitch roof. But both are types of pitched roof. As are a hip roof, a gambrel, a mansard, a gazebo, skilion, etc. What I had in mind wsa a exempt garage to the side, but touching the house, with a lean to type roof.

Obviously mono-pitch is not the first thing we think of. And various councils may take the view that a monopitch roof is excluded. But I'm not aware of a legal definition that segregates it.

That's not to say that ABP have not ruled on it, I've never done it. If we took the view that the walls could not expect past 3m, that would rule out gables, which I never heard of an issue with. Food for thought.
