Frequently Asked Questions

How close can I build to my neighbour’s boundary?

Extensions built close to a boundary must meet height and eaves restrictions, especially if within two metres of the boundary.

Can I install rooflights under permitted development?

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

Do I need planning permission for a rear extension in Headcorn?

Many rear extensions fall within permitted development limits, but projection depth, height, and boundary proximity must comply with national rules and any local restrictions.

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.

What is a Lawful Development Certificate?

A Lawful Development Certificate provides formal confirmation from the local authority that your extension complies with permitted development rules.

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.
