Dormer loft conversions are often permitted development within volume limits.

Can I add a balcony to my extension?

Balconies and raised platforms are not permitted development and usually require planning permission.

Can I extend a listed building?

Residential permitted development rights apply only within the residential curtilage.

Can I build a wraparound extension without planning permission?

Wraparound extensions often exceed permitted development limits and usually require planning approval.

Can I build a two-storey extension without planning permission?

Two-storey extensions are sometimes permitted, but stricter limits apply to height, rear projection distance, and window placement to avoid overlooking neighbours.
