Frequently Asked Questions

Do I need structural calculations?

Yes, building regulations often require structural calculations for beams, foundations, and load-bearing elements.

Are garden rooms permitted development?

Garden rooms may qualify if they meet size and usage limits and are not used as separate accommodation.

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 extend a house that has already been extended?

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

Does an Article 4 Direction affect my extension plans?

Yes. Article 4 Directions remove certain permitted development rights, meaning planning permission may be required.

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

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