    I am hoping to build a large shed (steel hay shed, perhaps two bays, say 15 by 10 metres) in my garden ( I live in a rural area, have farmland around me - am planning on using the shed as a workshop for my hobby - car, vintage vehicle restoration)
    Does anybody out there know what is the maximum size permissible without applying for planning permission?
    Has anyone built a similar shed with or without planning permission?

    Thanks in advance...

    I believe the following is correct

    You can build a garage, carport, shed, greenhouse, kennel for domestic pets etc, as long as it does not extend out in front of the building line of the house and does not exceed 4 metres in height, (if it has a tiled or slated pitched roof). Or 3 metres (if it has any other roof type). The floor area limitation for exempted development is 25 square metres. The structure may not be lived in, used for commercial purposes or be for keeping of pigs, poultry, pigeons, ponies or horses. Garages, sheds etc to the side of the house must match the finish of the house. You cannot reduce the open private space, reserved exclusively for the use of the occupants of the house, at the side or rear of the house below 25 square metres.

    Check with your local authority though. You can be made to remove the shed if for example a neighbour complains.

    Class 9 would be a better option.

    I think it is 25sqm on the side and 40sqm at the back.
    Anyway, exemption only applies if extension is attached to existing house afaik.

    the 40 sq m thing is for extensions, the 25 sq m thing is for garages / sheds....

    nutty nut, yes, class 9 would describe the use better than the class 6 i was referring to...

    I'm also thinking of building a shed near the house but protruding about 1m in front of the house line. Does this need permission, even if the shed is built from "non-permanent materials" such as wood, corrugated steel, etc.? It would be abot 27-28 sq. m in size and not visible from the public road..... Thanks.....:confused:

    Are portal frame sheds (large shed 2000sqft), where the shed is totally removable frome the site, exempted from permission?

    Yes they do require permission if they are domestic or business orientated.

    There is an exemption for agricultural sheds of that size but again they would only be exempt subject to certain conditions.

    'portable', 'temporary' or whatever makes absolutely no difference to its stautus of being exempt or not.

    there a common myth out there that a temporary building is somehow exempt... its not.

    A large agricultural shed in your back garden over 25sqm requires planning permission.

    IMO these sheds are too high and unsightly to be erected beside domestic dwellings. I see it time and time again - a beautiful house with a terrible "monster" shed in the garden!

    It could very well be, in most of these cases, that the activites that go on in the shed probably contribute to the upkeep of the beautiful house !

    Thats true but do you really need a "hay shed" in your garden?
    Why spend a lot of time & money building a beautiful home and then spoil it by building an ugly metal shed beside it.

    A standard 2 bay shed would have a floor area of 144sqm, being 12m x 12m internally and 6m high (20ft). Thats a bit excessive in a domestic setting. Its ideal for light industrial use, mechanical, farming or warehouse storage.

    Those interested in supplementing their income with a hobby, ie small scale carpentry etc will find a 30sqm or 40sqm single storey garage might provide ample room.

    Still, each to his own. (Maybe it more a case of size matters!)

    Any garage with a floor area over 25sqm requires planning permission. There are also height restrictions on exempted development.

    No, I disagree - internal gross floor area over 25sqm - as defined by Dept of Enviro - the same people that write the Building Regs & Planning Law.

    The old 1st time buyers grant or Floor Area Certificate are examples of internal gross floor Area, meassured internally.

    If you meassure a floor area for planning permission application, it is also meassurered internally - gross internal floor area. ( Even an Auctioneer will meassure the internal length by width to give buyers a total internal floor area.)

    Towget and RKQ are both right.

    For the shed to be considered exempted development, inter alia:

    The internal area of the shed cannot exceed 25 sqm
    The external area of the private open space must remain a minimum of 25 sqm

    There are other requirements, but these relate to area.

    FWIW
