Growing families, growing houses
Extensions and conversions in Haydon Wick
Haydon Wick grew with Swindon — street after street of practical family homes from the seventies through to the nineties, most of them with a decent garden and a layout that made sense at the time: kitchen at the back, dining room walled off, garage on the side that ends up storing everything except a car.
Most of what we do here is turning that layout into the one families actually want now. A rear or wraparound extension creates the big, light kitchen-diner; a knock-through opens the ground floor up; a garage conversion turns dead storage into an office, playroom or fourth bedroom. Often it’s a combination — and because one firm designs, builds and manages the whole job, the finished house feels like it was always meant to be that way.
Every project is priced in a fixed written quotation after a site visit, built by our own hand-picked team, and signed off by Building Control — with a 10-year insurance-backed guarantee on major work. If the numbers need to start smaller, our guide prices are published openly so you can plan honestly from day one.

Builders in Haydon Wick — FAQs
Common questions
Do I need planning permission to extend in Haydon Wick?
Often not — many single-storey rear extensions on Haydon Wick’s estate houses fall under permitted development rights. Larger, double-storey or corner-plot builds may need approval. We assess it at the site visit and tell you straight before any money is spent.
How long does a rear extension take?
Most house extensions take between 8 and 16 weeks depending on size and complexity. You get a clear timeline with the quote, and the project is personally managed from start to Building Control sign-off.
Is a garage conversion worth it?
Usually, yes — it’s a room you already own. Done compliantly with insulation, damp-proofing and Building Control sign-off, a garage conversion is one of the most cost-effective ways to add living space, typically £1,400–£2,000 per m² as a guide.
Can you open up the kitchen and dining room?
Yes — knock-throughs are a large part of our work. If the wall is load-bearing, a structural engineer specifies the steel, the load is supported properly during the work, and Building Control signs it off. All handled as part of the job.
