Highlights
"I had half of my garage converted into a studio office, including new walls, soundproofing, lighting and electrical work, heating installation, and decorating. The standard of work was excellent and the whole project was managed brilliantly by Ian. Ian and his team were a pleasure to work with: professional, friendly, and very respectful of our home, always checking in on the details and working around our schedule. I’m absolutely delighted with the finished space and wouldn’t hesitate to recommend them."
"DH1 design and build fitted a new shower enclosure with associated floor and wall tiling to match. Very pleased with the result. Graham and Mark were both professional and polite at all times. Everything was left tidy afterwards Would definitely recommend them."
"From the initial survey to costing and planning regs, everything was handled well. Clear scope so we knew exactly what was going on. The work took place as indicated, punctual, tidy, friendly and good quality. Highly recommended. Any concerns or queries addressed or answered straight away. I don’t say this often but these guys are tradesmen that are a pleasure to deal with."

Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
