This guide explains planning permission rules affecting dormer extension developments in Basildon.
Most householder development follows national permitted development rules unless local restrictions apply.
Development must comply with national permitted development height limits.
Whilst many Town and Parish Councils do engage with the community and seek their views, such engagement is not necessary to enable consultation responses to be provided and individual members of the public should continue to respond individually to enable their views to be heard. Therefore, for the vast majority of applications, the Council does not see the need to extend the period of time to respond. However, there will be applications where exceptions need to be made such as in respect of major and/or complex applications. In such circumstances please liaise with the appointed case officer and where possible, we will look to accommodate those requests.
Development near boundaries must follow national permitted development rules.
Roof alterations must comply with national permitted development rules.
Materials should be similar in appearance to the existing house.
Additional planning restrictions may apply in conservation areas.
