Frequently Asked Questions

Can I build right up to my boundary?

It depends on height and location. Boundary proximity affects allowable eaves height.

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.

How high can my extension be?

Height limits vary, but rear extensions under permitted development generally cannot exceed four metres for detached houses or three metres for others.

Are side extensions allowed under permitted development?

Side extensions are permitted in some cases, but must not exceed half the width of the original house and must meet height limits.

Does my extension need to match existing materials?

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

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.
