A basic guide to Planning Permission and Permitted Development.
Three different types of planning applications.
Pre App – Pre App’s enquiries are free of charge, the council will assess your plans/proposal and give you there opinion. This is done prior to submitting a DPP Detailed Planning Permission or PPP planning permission in principle. PPP
PPP – Planning Permission in Principle is a simpler application this is submitted to check that the scope of work is in principle ok with regards to planning. You won’t need to provide as much information as you would with detailed planning permission.
DPP – Detailed Planning Permission is where you have to fully outline the scope of work. This would involve a full set of plans, elevations, any drainage requirements, drainage impact assessments, habitat surveys, bat surveys would need to be submitted with a full planning application which is a DPP.
There are some works that are permitted under permitted development rights. These need to fit in with the constraints of the criteria, which is basically you can develop an extension, Loft Conversion or dormers. These fall under permitted development rights, these have to meet the criteria of being within a metre of the boundary, the total height does not exceed more than four metres to the roof peak and the height to the eaves does not exceed more than three metres. Some dormer windows on the rear elevation can be permitted under permitted development rights, if it is under 50% of the rear curtilage (width of the property), you have a garden bigger than 10 metres to the boundary, The outer cheek of an end dormer should be positioned at least 700mm in from the face of the gable wall or 1000mm from the verge, is within 300mm from the ridge and be at least 400mm in from the inside face of the tabling. This can vary between traditional and new style properties.
There are also a few other planning applications which are worth noting. Even if you fall under the criteria above for permitted development rights, there are certain circumstances where the building is either a listed building or in a conservation area, you’ll always need to do a planning application. If you have existing Velux windows and wanted to replace them with a different size would need planning permission. However, if you just wanted to put in a new Velux window of the same size, this would fall under Permitted developments Rights.
There are other types of planning consent, such as signage and advertisement consent, listed building consent and conservation area application as well.
