Don't hesitate in booking these guys! After getting a few quotes we decided to go with JCT for our kitchen renovation due to the fair price and great communication. We live in a 142 year old Victorian semi and Jamie and his team did an incredible job...

The most common questions homeowners ask us before booking a site visit.
A single-storey rear extension in Kidderminster typically costs between £25,000 and £55,000, depending on size and specification. Premium kitchen extensions with bi-folds and roof lanterns reach £55,000–£75,000. Double-storey extensions range from £55,000 to £130,000. JCT Building provides fully itemised, written quotes after a free site visit so you know exactly what each element costs before you commit.
A single-storey rear extension takes 8–12 weeks from groundworks to handover. Double-storey extensions and large wraparound builds take 12–18 weeks. Combined renovation-plus-extension projects can run 16–28 weeks. JCT Building shares a Gantt-style schedule at the start of every project and provides weekly progress updates so you always know where things stand.
Most single-storey rear extensions in Worcestershire fall under Permitted Development rights — meaning no formal planning permission is required, provided the build meets size limits (4m projection on detached homes, 3m on semis/terraces). Two-storey extensions, listed buildings, properties in conservation areas, and homes with Article 4 directions need full planning. JCT Building handles the planning assessment as part of every free quote.
