Highlights
"John is fantastic. He was first recommended to us around 15 years ago, and since then he’s built our extension, garden room, shelving and alcove units, installed new bathroom. He’s fabulous! Highly recommend."
"John has been professional from start to finish. He really listens, asks the right questions, and gives clear advice—especially when you're unsure on parts of the design. He fitted wardrobes for me and gave great guidance on drop heights, drawer sizes, and finishes. The quality and attention to detail is outstanding. He’s fairly priced and worth every penny, if you want high-quality results. There’s a reason he’s in demand! Highly recommended. Note: wardrobe handles I ordered were delayed, so still pending when I took the photos."
"John was fantastic from start to finish. He was very responsive on messages and fitted us in really quickly. He was reliable, very tidy and a brilliant job. I would highly recommend him and will definitely be using him again."

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.
