Areas we cover — West London · Bucks · Herts

Your vision deserves more than a builder. It deserves a team you can trust.

We design, build and transform homes across West London, Buckinghamshire and Hertfordshire. Our own architectural designers and structural engineers work alongside our build team, so one company owns your project from the first sketch to the final finish.

Free and without obligation. We reply within one working day.

Our approach

Building work should be straightforward, professionally managed and built to last. Your home is one of the biggest investments you'll make — so we never treat a project as just another job.

Built with experience.

  • In-house architectural designers who draw up your plans
  • Structural engineers involved from inception to completion
  • Planning and building control managed for you

Managed with care.

  • One named project manager from first visit to handover
  • A written progress update every week
  • A tidy site, and neighbours told before work begins

Finished with pride.

  • A room-by-room snagging walk-through before handover
  • An aftercare visit at six months
  • An insurance-backed guarantee on our work

Design & build

Designed, engineered and built by one team.

One contract · one point of contact · inception to completion

How design & build works

  • One point of accountabilityNo gaps, and no finger-pointing, between the people who design your home and the people who build it.
  • An engineer from the first sketchOur structural engineers are involved from inception to completion, so what's drawn is buildable — and priced accordingly.
  • Costs known earlierThe design is costed as it develops rather than after planning, so the fixed price holds fewer surprises.
  • Already have an architect? We'll build to their drawings with exactly the same care.

Clear communication★★★★★
“I recently had my home fully refurbished and the experience with AMH Build Group was outstanding from start to finish. The team was professional, organised, and genuinely cared about the quality of the work. Every stage — from the initial walkthrough to the final finishes — was handled with clear communication and zero stress. They kept the site tidy, respected timelines, and delivered craftsmanship that exceeded expectations. The attention to detail on the joinery, flooring, and overall finish has completely transformed the space. It’s rare to find builders who are this reliable and honest. I’d recommend them without hesitation.”

Trusted to deliver★★★★★
“We bought our home in May that needed pretty much everything doing to it before we could move in, and to be honest, we were quite nervous about the whole process. […] The house has been completely transformed and the finish throughout is excellent. One of the biggest things for us was how clean and organised they kept everything.”
Andrew W.Whole-house renovation · Google review
Fast, friendly & clean★★★★★
“We have recently had our double storey extension built by AMH in Uxbridge. An amazing job done by an amazing team, thanks AMH for all the work. A really friendly team who work exceptionally hard and most importantly fast. We lived in our property throughout our renovations and the team were exceptional in ensuring cleanliness and protecting the rest of the house from dust and dirt. Will be calling them back for future work.”
