In most cases the answer is no. A garden shed in England is usually treated as an outbuilding and can be erected under permitted development rights, set out in the Town and Country Planning (General Permitted Development) (England) Order 2015, without an application to the local planning authority. Those rights come with conditions, and it is the conditions rather than the principle that catch people out.<\/p>\n
The three that matter most are height, position and coverage. A shed placed close to a boundary is limited to a much lower overall height than one in the middle of a garden, nothing may be built forward of the principal elevation facing a highway, and outbuildings together with other additions must not cover more than half the land around the original house. Get those three right and permitted development usually applies. Get any one wrong and an application becomes necessary, whatever the shed itself looks like.<\/p>\n
Permitted development is not a blanket permission. It is a set of limits, and an outbuilding stays within them only if every condition is met. The building must be incidental to the enjoyment of the dwelling house, which covers ordinary sheds, workshops, garden stores and garden rooms used as such, but does not extend to self contained living accommodation.<\/p>\n
It must be single storey. Eaves height is capped at 2.5m. Overall height is capped at 4m where the roof is dual pitched and 3m for any other roof form, including the mono pitch roofs common on modern sheds. Crucially, if any part of the building sits within 2m of a boundary of the property, the maximum overall height falls to 2.5m, which rules out a great many standard apex sheds placed along a fence line.<\/p>\n
Position matters as well. No part of the outbuilding may be forward of the principal elevation fronting a highway. Verandas, balconies and raised platforms are not permitted, with a raised platform generally understood as a floor level above a set low threshold, so decking or a plinth raising a shed floor should be checked carefully.<\/p>\n
Finally there is coverage. Outbuildings and other extensions together must not exceed half the total area of land around the original house. The word original is doing real work: it refers to the house as it stood on 1 July 1948, or as first built if later, so previous owners’ extensions count against your allowance.<\/p>\n
On designated land the position changes. In conservation areas, National Parks, Areas of Outstanding Natural Beauty, the Broads and World Heritage Sites, outbuildings to the side of the house are not permitted development, and buildings more than 20m from any wall of the house are restricted to a small footprint. Listed buildings carry their own separate consent regime, and works within their curtilage can require listed building consent even when planning permission is not needed.<\/p>\n
Some properties also have permitted development rights removed by condition, commonly on newer housing estates, through what is known as an Article 4 direction or through planning conditions attached to the original approval. Because this is invisible from the street, checking the property’s planning history with the local authority is always worth the time before ordering a large building.<\/p>\n
Covenants in the title deeds are a separate legal matter again, unaffected by planning law, and can restrict outbuildings on land that planning rules would otherwise allow. This is common on former estate land and modern developments alike. The practical sequence is therefore: check the deeds, check for an Article 4 direction or conditions, then check the permitted development limits. Only then choose from the garden sheds and storage UK<\/a> designs that fit the envelope you are allowed.<\/p>\n The table below summarises the main English limits in one place.<\/p>\n Permitted development limits for domestic outbuildings in England, as set out in the 2015 Order.<\/p>\n
