Home Extensions

Ashenbury Construction delivers single-storey and double-storey extensions that add real, usable space and value. We handle side-return, rear and wrap-around extensions, and we’re known for turning kitchens into open-plan kitchen/living spaces that improve flow and light.

If you’re comparing options, we’ll give clear guidance on extension cost (including per-m² ranges for single-storey and double-storey builds) and realistic timelines.

Unsure about rules? We’ll confirm whether your project fits permitted development or needs planning permission, and advise on how far you can extend without planning permission in your area.

From structural steelwork to finishes, our team manages the detail so your extension is delivered cleanly, on schedule, and ready to live in.
