“CJA Building were fantastic to work with from start to finish.

Their building work was of a really high standard and we were particularly impressed with Callum’s project management, communicating with us, and keeping things on schedule.

We will definitely be using them again in the future!”

— Neil, Hitchin

“We had the pleasure of selecting Callum and his team to manage our garage conversion and first floor extension. The project was a tricky one as we had encountered various planning issues thereby requiring some unusual design features and attention to detail.

Overall our experience was amazing. The professional, ethic and organisation was perfect and we were delighted with the finished project.

Callum is a problem solver and extremely innovative always going the extra mile to deliver against brief. Highly recommended.”

— Liz & Grant, Hitchin

“We were really impressed with their work building our extension in 2020. They were easy to get in touch with, straightforward to work with and had some great ideas - there's no doubt they saved us money and we were really pleased with the quality of the work throughout.

They went out of their way to ensure we could stay living in the house for as long as possible during the work, were always careful to ensure nothing hazardous was left around for our young daughter to find, and had some great recommendations for features along the way.

Callum co-ordinated everything from the plasterers to the electricians and plumbers to ensure the build ran as smoothly as possible, and helped us overcome any problems we ran into along the way.

We have recommended them to friends, and would happily do so again.”

— Wes & Carla, Hitchin

“They did an amazing job and we love the space they created.

They turned up when they said they would and were consistently polite, easy going, hard working and highly skilled at what they do.

Callum always replied quickly to messages and would always go above and beyond with advice and help.

Working on a busy road with tricky parking and terraced houses can present certain challenges but they navigated all the hurdles with good humour and consideration to those who live on our street.

They were honest, trustworthy and completely dependable. We can’t recommend them highly enough and wouldn’t hesitate to use them again.”

— Anne & Matt, Hitchin

“Callum recently undertook an extension to our property. Throughout the process they kept us informed and consulted regularly as questions arose.

They were accommodating, easy to work with and considerate of their impact during the whole building process.

We have been delighted with the finished build which has completely transformed the way we use our house. We would use them again without hesitation should the need ever arise in future.”

— Paul & Siobhan Hitchin

“The thing that really sets Callum apart from other builders we’ve dealt with is the great communication throughout the project.

He respected the fact this isn’t just a building site, it’s our home. That’s really important – and rare to find – but especially when you’ve got a young family. You need to choose a builder that you’re happy to have arrive at your home every day.

The quality of workmanship was super high and Callum was always happy to accommodate our requests throughout. We recommend him to anyone who’ll listen!”

— Dan & Liz, Hitchin

“We knew we wanted to open up our ground floor living space to comfortably house our ever growing family now grandchildren have arrived, but we had no vision as to how we would go about it.

Through asking us a series of questions, Callum managed to put together a sketch of how he thought we visioned it. He flagged up a lot of idea’s which we would never have considered, these were invaluable to the final result.

Callum’s team were a great bunch of friendly, polite, highly skilled individuals, who worked together to ensure our build ran smoothly without delays, and in no time that sketch became a reality.

To say that we are delighted is an understatement. The transformation blew our minds, and still does on a daily basis.”

— Sheilagh & Symon, Hitchin
