Why Choose Us

Sheffield's Most Trusted Build Team

I'm Mark Hadfield, and I started Peak Build in 2009 after 10 years working for other firms. I wanted to do things my way - price honestly, communicate properly, and leave every site cleaner than we found it. Fifteen years later, that hasn't changed. We're a crew of 6, and we still treat a £15k extension the same as a £300k new build.

What Clients Say

“Mark and the lads built our rear extension in 10 weeks flat. On time, on budget, and the finish is outstanding. Wouldn't use anyone else.”

Steve R.

Homeowner, Crookes

“We had three quotes and Peak Build wasn't the cheapest - but the detail in their quote and the way Mark explained everything made us trust them. Best decision we made.”

Lisa M.

Homeowner, Hillsborough

“Third time using Peak Build. Drainage, extension, and now a loft conversion. Reliable, fair, and the work speaks for itself.”

Dave T.

Homeowner, Dore
