What We Build
Garden rooms are all Gary does now. Forty years of extensions, roofs and groundworks went into learning how to build one properly. That's why ours still look right ten winters later.
Bar, snug, somewhere to watch the match in peace. Soundproofed so it stays yours, and wired properly for the telly, the fridge and the sound system.
A proper place to work, thirty seconds from the back door. Warm in January, cool in July, and quiet enough that nobody on the call can tell where you are.
A floor that takes a loaded barbell without flexing, ventilation that actually shifts the air, and room for a rack and a platform.
Somewhere for guests, teenagers or family to stay properly, with a shower room, heating and insulation to full residential standard.
Gary started as an apprentice in 1986. Since then he has built extensions, re-roofed half the street and poured more concrete than he cares to think about. These days he only builds garden rooms, most of them clad in western red cedar, because it's the one job where doing it properly still shows.
He takes one job at a time. That means your build gets finished before the next one starts, and when you ring the number on this page, he's the one who answers it.

The Specification
Anyone can make a garden building look smart for one summer. You find out what it is really made of in year three. Here is exactly what goes into every room Gary builds, written down so you can hold him to it.
Concrete or ground screws depending on your ground, levelled and damp proofed. Whatever suits the plot, not whatever is quickest.
Kiln dried, treated, built at 400mm centres. Stronger than it needs to be, on purpose.
Walls, floor and roof, with a taped vapour barrier. Warm in winter without the heater running all day.
Slow grown cedar, fixed with stainless steel so it never streaks. Oil it to keep the colour or let it silver, both look right. Larch and composite are there if you would rather.
One single piece, so there are no joints to fail. Guttering run off to a soakaway.
Bifold or sliding doors, double or triple glazed, thermally broken, multi point locks. Hardwood frames if you prefer.
Armoured cable from the house, its own consumer unit, sockets and lights to your plan. Certificate handed over on the last day.
Prices
Most builders won't put a price anywhere near their website. Here are ours. These are real starting prices for a finished room, with the base, the building, the glazing, the electrics and the decorating all included.
3m x 3m, 9m²
Office, studio or a quiet room to read in. Fits a desk, a two seater and storage without feeling tight.
5m x 3.5m, 17.5m²
The classic cedar man cave or garden gym. Room for a bar and seating, or a full rack and a platform.
6m x 4m, 24m²
Split room layouts, guest annexes with a shower room, or a gym and snug in one building.
Ground conditions, access and bespoke glazing can move the number either way. That is exactly why the survey is free and the quote is fixed in writing before anyone commits to anything.
How It Works
From the first phone call to the day you get the keys is usually six to eight weeks.
Two minutes on the phone, or send a few photos over WhatsApp. He'll tell you there and then whether it's a job he can do, and roughly what it'll cost.
He comes out, measures up, checks the access and the ground, and works out what you actually want to use it for.
A full specification and one fixed price, emailed within 48 hours. It stands for 90 days, so there's no rush on you.
Two to four weeks on site for most rooms. Tidied up every evening. Certificates, guarantee and keys on the last day.
Recent Work
We would rather show you a handful we are genuinely proud of than thirty photos of the same building. If you want to see one in the flesh, Gary can usually arrange for you to visit a finished room nearby.
Two minutes on the phone and Gary will give you an honest idea of the price.

“We use it all year round. It was minus two in January and I had the heater off by ten in the morning.”
“Three other quotes were a paragraph long. Gary's was four pages and explained every material. That is why we went with him.”
Areas We Cover
Gary works across Cardiff and the Vale of Glamorgan. If your town isn't on the list, ring him anyway. For the right job he'll travel a bit further.
