Frequently Asked Questions

Does my extension need to match existing materials?

While not always mandatory under permitted development, matching materials is often recommended for visual consistency.

Can I install rooflights under permitted development?

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

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 add a balcony to my extension?

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

Can I build right up to my boundary?
