We feel incredibly lucky to be working with Format Build on our Dutch barn conversion.
From the very beginning, their professionalism, attention to detail, and the sheer quality of their workmanship have been exceptional.
Every phase of the project has been approached with care, precision, and an unwavering commitment to excellence.
Format Build work to the highest standard -there are no shortcuts, no compromises-and that's evident in everything they do.
Their quality is truly unrivalled, and it's clear they take immense pride in their craft.
But what means the most to us is the trust we have in them. That kind of trust doesn't come easily, but Format Build have earned it at every turn. We know our home is in the safest, most capable hands, and that peace of mind is invaluable.

If you're looking for a contractor who will treat your project with the same respect and dedication as if it were their own, we couldn't recommend Format Build more highly.

We couldn’t be more thrilled with the transformation of our Grade II listed property, thanks to the incredible team at Format Designs. From the initial design concepts through to the final execution, their expertise and attention to detail were outstanding.
They not only understood our vision — they brought it to life in ways we hadn’t imagined. Completing a full interior renovation in under six months is no small feat, and they managed it with professionalism, creativity, and a level of care that truly sets them apart.
Their design has not only given us a beautiful home, but has genuinely transformed many aspects of our lives. The interiors are calming, welcoming, and serene — they’ve changed the way we feel and live each day.
What impressed us most was their flexibility and the genuine friendliness of the entire team. It’s rare to find a company so talented and so easy to work with. We wouldn’t hesitate to recommend Format Designs to anyone looking for exceptional design and delivery.

Sara was quite simply fantastic. 
We had meetings with a few designers, but both my husband and I could tell instantly that Sara understood what we were looking for, and was very professional in her approach. 
Sara’s attention to detail and her professional manner across the whole project was second to none and we would not hesitate to recommend her services to anyone. 
She got to know us and our personalities straight away. I've always struggled with knowing what I like, so she quickly focused on what I didn't like and built from that. We love how approachable she is, making it easy to have conversations through out the whole process.
You both built our confidence in knowing the styles and colours we like and you have helped us fall in love with our house all over again. Sitting in our new garden room simply brings joy and relaxation.

We have engaged Format designs for several projects at our house in Welwyn over the last 3 years and have been so impressed with their work. From start to finish they have taken care of each minor detail from initial design to the full refurbishment work. The link up of Matt & Sara on the same team really works well. Sara's design & vision is imputed by Matt & his team extremely well. The key factors I always review tradespeople on is; communication, reliability, quality of finish and how tidy they are and I would give them a 10 out of 10 for each. Thank you once again for making our house a lovely home.

Format Designs have been so professional from the start, working with the franchise to make sure we include every aspect they require to keep the continuity of brand but to adjust the flow to the space we were working with.This came with it’s own set of issues, all of which Sara overcame with ease. The team were a pleasure to work with and I look forward to the next one.

Format Designs handled everything from the first design to the final touches including planning permissions and project management. Nothing was too much trouble and everything always felt under control and in safe hands leading to a stress free project for us. We are delighted with the final result and so are our customers.

We commissioned Format Designs to undertake the design & build for our flagship retail store relocation. This involved changing it from an outdated, takeaway only store to an 'on trend' sit in style Bakery Cafe. Being our biggest business decision & investment to date we went with the team based on how they really took the time to understand our business, its needs & how the finished product should feel, not just look. It's safe to say they surpassed every expectation & the results of our new store really speaks for itself.”

Throughout the process Format were brilliant to work with. They were extremely thorough with measurements & careful with cost vs budget whilst prioritising key design elements that added value (sometimes in clever ways to meet our needs!). We really liked how nothing was too much trouble, especially if we changed things several times or pushed the boundaries of what was possible. When the time comes to open our second store, Format will be the first firm we contact.
