Why extend
Moving costs more than you think. Extending solves the actual problem.
Stamp duty, agent fees, removals and the stress of a chain rarely add up to a better home. The right extension can give you the kitchen-diner, utility, extra bedroom or family room you actually need — in the home you already love.
- Open-plan kitchen-diners with proper utility and storage
- Wrap-arounds that fix period-home flow on the ground floor
- Double-storey extensions when you need bedrooms as well as space
- Over-garage extensions for an extra bedroom, study or en-suite
Services
Extensions we design and build
From compact side-return infills to substantial double-storey rears, every project goes through the same managed process — clear scope, realistic budget, one team from drawing to handover.
From £55k–£90k+
Double-storey extensions
Adding space across two floors — typically a bigger kitchen below and a bedroom or en-suite above, when you need bedrooms as well as living space.

FAQs
Frequently asked questions
Do I need planning permission for an extension in the West Midlands?
Some extensions fall under permitted development, but eligibility depends on the exact property, plot and proposal. We confirm the likely route on every project and apply on your behalf where needed. Read our planning guide.
How much does an extension cost?
Indicative ranges: single-storey rear from £30k–£55k+, side-return from £25k–£45k+, wrap-around from £45k–£85k+, double-storey from £55k–£90k+. Final pricing depends on size, glazing, kitchen spec, ground conditions and finishes. See full cost guide.
How long does an extension take to build?
Single-storey extensions typically 10–14 weeks on site. Double-storey extensions and wrap-arounds typically 16–22 weeks. Planning and design lead in before that, usually 8–14 weeks.
