Planning Application Guide

Development Idea

You have a building project in mind or you wish to change the use of a building or land you own or are thinking of buying.


Permitted Development

Permitted development is development that can be carried out without the need to apply for planning permission, as it is already granted by the Town and Country Planning (General Permitted Development) Order 1995 (GPDO), as amended for Wales.

The Welsh Government provides planning guidance to support their application service. The guidance covers planning and building regulations advice for many common building work projects for the home. This advice is specific to the planning and building rules in Wales.

You will need to establish whether this development is possible without the need to submit a planning application. Some alterations can be carried out under permitted development. Please follow the link to find some common householder projects that can fall under permitted development.

If planning is required or you have land to develop

At the development idea stage, applicants should start to think about material planning considerations. A material consideration is a matter that should be taken into account in deciding a planning application or on an appeal against a planning decision.

Material considerations can include (but are not limited to):

  • Planning policy 
  • Highway access
  • Flood map
  • Overlooking/loss of privacy
  • Loss of light or overshadowing
  • Traffic
  • Noise
  • Effect on listed building and conservation area
  • Layout and density of building
  • Design, appearance and materials
  • Disabled persons' access
  • Proposals in the Development Plan
  • Previous planning decisions (including appeal decisions)
  • Nature conservation

However, issues such as loss of view, or negative effect on the value of properties are not material considerations.

We will take you through each stage of the application process to give you a clear understanding of the process.
