Extensions
Single and two-storey extensions, kitchen and living space, built to give you the room you need without moving house.

Extensions, conversions, renovations, groundworks and general building — managed from the first plans right through to completion, by a small team that turns up, does it right, and leaves it tidy.
Established in 2001 and still hands-on across every job, from the groundwork up.
Plain prices and plain English. If it isn't right, or isn't worth doing, you'll be told straight.
A reputation built entirely on recommendation — the work is the advertising.
A small team you'll actually deal with — Neil on the job, not a call centre.
Coates Construction is a general builder and contractor — which means we take the whole job from the first plans right through to completion, all with one trusted team, without you having to chase half a dozen different trades.

For over twenty years, Neil Coates has built his name the hard way — one honest job at a time, on work solid enough that customers pass his number to their friends and family without a second thought.
There was never a logo, a website or an advert. Just the work, and the word of the people he'd done it for. This site exists for one reason: to make Neil easier to find for the next person who needs a builder they can actually trust.
A handful of recent projects Neil and the team have finished across Catterick, Richmond and North Yorkshire — from full extensions to bespoke joinery.

Yes. Coates Construction is based in Catterick and covers Richmond, Leyburn, Bedale, Northallerton, Darlington, Ripon and the surrounding North Yorkshire villages. If you're not sure whether your job falls within reach, just ask on WhatsApp.
It depends on the size and scope of the job — many extensions and conversions fall under permitted development, while others need full planning permission or building regulations sign-off. Neil will talk you through what your project needs when he comes to look at it, and can point you to the right people if a formal application is required.
It varies with the size and complexity of the job — a single-storey extension is a different timescale to a full renovation. You'll get a realistic timeframe as part of your quote, not just a price, so you know what to expect before work starts.
Yes — quotes are free and no-obligation. Message a couple of photos and a few lines on WhatsApp, and Neil will come out, have a proper look, and give you a clear price.
Coates Construction is a tight, trusted team of three — Neil, Mick and Max — with specialist, long-trusted contractors brought in for specialist work when needed. You deal directly with the same people throughout your job, not a rotating crew.
Send a message on WhatsApp with a couple of photos and what you've got in mind. Neil will come and take a look, then give you a proper price — no obligation.
