In England, a shed or other garden outbuilding can often be installed under permitted development if the property and project meet all the conditions. Start by checking the planned position, overall height and intended use.
Check the distance from your boundary
If any part of the building is within 2 metres of your property boundary, the permitted development limit is 2.5 metres in overall height. For buildings farther from the boundary, the usual overall limits are 4 metres for a dual-pitched roof and 3 metres for other roof types. The eaves limit is 2.5 metres. Check how the height is measured before choosing a building or base.
Check the other conditions
Where you position the building, how much of the garden is already covered, and whether your property is listed or subject to special restrictions can all affect what is allowed. Building regulations are a separate check.
Read the Planning Portal’s guidance for outbuildings and ask your local planning authority if you are unsure. Ask us for the dimensions of any model you are considering.
