Frequently Asked Questions

Can I extend onto agricultural land?

Residential permitted development rights apply only within the residential curtilage.

Are there restrictions on side-facing windows?

Yes. Upper-floor side-facing windows typically must be obscure-glazed and non-opening below a certain height.

Does my extension need to match existing materials?

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

Are garden rooms permitted development?

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

Can I convert my loft and add a dormer?

Dormer loft conversions are often permitted development within volume limits.

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.
