Budget rebuild/repair of wooden garage.

I'm not entirely sure thats correct, I believe anything that doesn't fall under permitted development needs either temporary or permanent planning permission no matter what its made of.

I had a timber garage at my parents house and it was very good but the metal roof was  nightmare for condenstation, especially when I insulated it and tried to heat it.

this is what I’ve found online from a few places now. 

Generally, ‘outbuildings’ are categorized as ‘permitted developments’, which means that no planning permission would be required for a wooden garage providing you build the structure in line with the following rules:

* You should not build a garage forward of the main elevation of the original house.

* Your log cabin, along with any other outbuildings, should not take up more than 50% of the total area of land around the original property.

* You should not use a garage as a living space.

* Wooden garages should be a single storey log cabin.

* In the case of a dual pitched roof, the maximum total height of your wooden garage should be 4 metres and the maximum eaves height should be 2.5 metres. Any other type of roof should have a maximum overall height of 3 metres.

* If a log cabin is built within 2 metres of the boundary of the house, the whole garage structure should not be more than 2.5 metres high.

it will be a completely wooden structure. I won’t have a metal roof. 

more I look online there’s hundreds of places making garage etc, very few give you a price until you contact them, but I don’t really know how big I can have until I move in a rip down the old one. 

thanks
