Frequently Asked Questions

Will permitted development rules change?

Planning legislation can change over time, so it is important to check current regulations.

How high can my extension be?

Height limits vary, but rear extensions under permitted development generally cannot exceed four metres for detached houses or three metres for others.

Can I install rooflights under permitted development?

Rooflights are often permitted if they do not protrude significantly beyond the roof slope.

Are there restrictions on side-facing windows?

Yes. Upper-floor side-facing windows typically must be obscure-glazed and non-opening below a certain height.

Do I need planning permission for a loft conversion?

Many loft conversions are permitted development, but dormer size, roof alterations, and conservation area status may affect eligibility.

Can I extend a house that has already been extended?

Permitted development limits are cumulative, so previous extensions may reduce what is still allowed.
