Current Planning Guidelines

Your proposed design will fall into one of two categories, a permitted development or one which requires planning permission. The documentation / plans you require for works to be completed are fundamentally the same – however, one will require a planning application to be submitted and the other will not. Both will require a Building Regulations Application.


Detached Properties: A single-storey rear extension up to 4 metres in depth can be added without the need for any planning permission.

Semi-detached or terraced properties: The maximum depth which can be added is reduced to 3 metres without the need for planning permission.

Two storey rear extensions on all properties: These must be no more than 3 metres deep and not fall within 2 metres of a boundary line. In a further change to the current regulations there will no longer be a maximum volume allowance for ground based extensions.

Loft Conversions

Lofts to detached properties can be converted without planning permission so long as any dormers do not add more than 50 cubic metres to the property. The allowance is reduced to 40 cubic metres for semi-detached and terraced houses. Dormer windows are not permitted to an elevation facing a highway.
