Frequently Asked Questions

Can I extend a semi-detached house differently to a detached house?

Yes, size limits and projection distances differ depending on property type.

Can I extend a house that has already been extended?

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

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.

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 install rooflights under permitted development?

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

Can I submit planning drawings myself?

Yes, but professional plans improve clarity and reduce refusal risk.
