Planning permission and permitted development rights

The loft will need approval if it is on the front elevation. The rear single extension will need approval if it more than 6m deep. The side extension will need approval. Landscaping will need approval for boundary treatment and if in a Conservation area. Basement work is P.D. Anything in a Conservation Area needs Planning Approval.

A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions: A volume allowance of 40 cubic metres additional roof space for terraced houses* A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway No extension to be higher than the highest part of the roof Materials to be similar in appearance to the existing house No verandas, balconies or raised platforms Single-storey rear extension must not extend beyond the rear wall of the original house* by more than three metres if an attached house or by four metres if a detached house.In addition, outside Article 2(3) designated land* and Sites of Special Scientific Interest the limit is increased to 6m if an attached house and 8m if a detached house until 30 May 2019. These increased limits (between 3m and 6m and between 4m and 8m respectively) are subject to the prior notification of the proposal to the Local Planning Authority and the implementation of a neighbour consultation scheme. If objections are received, the proposal might not be allowed. Side extensions to be a single storey with a maximum height of four metres and width no more than half that of the original house. Its fall under permitted development otherwise Planning application will be required Planning is all about outer permiters such as depth, width, height facing materials etc internal alterations you can show or can be changed later as well subject to building control approval

Even if some of the work can be done under PD rights, if that work includes some work that requires Planning Permission then it all must be drawn and shown on that application. BUT if it can be done in stages then apply for planning permission for the stage that needs it and then, if the PD rules still apply, build the later stages.
