How to read planning applications near a home

Read the application, drawings, decision and conditions. A map pin or application count cannot show the scale, outlook or construction effect.

Decision periods

The usual decision period is 8 weeks for standard applications, 13 weeks for major development and 16 weeks where an environmental impact assessment is required, unless a written extension is agreed.

Permission and delivery

Permission usually needs to be started within 3 years. Check whether conditions were discharged and whether work began, rather than assuming every approval will be built.

Reading the file

Compare the proposed height, massing, windows, access and working hours with the home you are considering. The decision notice and approved drawings establish what was allowed.
