Common questions
How much does a house extension cost?
Extension costs vary with size, specification and site conditions. As a guide, single-storey extensions in Herefordshire typically start from around £1,800–£2,800 per m² for a premium finish. We provide detailed itemised quotations so you know exactly where every pound is being spent.
Do you provide free quotations?
Yes — every quotation is free and provided in writing following a site visit. There's no obligation and no pressure.
Are you fully insured?
Yes. We hold comprehensive public liability insurance and appropriate cover for all works we carry out, and we can provide certificates on request.
Can you install RSJs and remove load-bearing walls?
Absolutely. We work with structural engineers to specify the correct steels, obtain building control approval, and install them safely with minimal disruption to your home.
Do I need planning permission for an extension?
Many extensions fall under Permitted Development, but this depends on size, location and property type. We'll advise on your specific project and can liaise with architects and planning consultants where required.
