Frequently Asked Questions

Can I amend my plans after submission?

Minor amendments may be accepted during determination, depending on the council.

Can I extend a house that has already been extended?

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

Can I install rooflights under permitted development?

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

What measurements are used for height?

Height is typically measured from the highest ground level adjacent to the building.

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 convert my loft and add a dormer?

Dormer loft conversions are often permitted development within volume limits.
