Jon was very responsive and rapidly provided an excellent survey for us. We needed a structural survey on an unusual property which is built into a rock face. Jon was very knowledgeable and helpful and we would definitely recommend his services!

We have worked with Jon on a number of projects over the last few years.

These now include a project at his own property – completed in summer 2024.

Jon is of course a very professional Structural Engineer. That almost goes without saying as he is a Fellow of the Institute of Structural Engineers and lectures (on a part time basis) in Structural Design at Sheffield University.

Equally important to us from a business perspective however is that Jon is very responsive, and open to ideas and questions. He is highly personable, knowledgeable, collaborative and is a genuine pleasure to work with as a fellow team member or indeed as a customer.

Any construction project would benefit greatly from having Jon on board.

I contacted Jon at short notice to do a structural beam calculation for a loft conversion. Even though he had a busy schedule he managed to fit me in and visit the location. Within a few days Jon had produced several detailed sketches and full detailed specification. During this time he was very quick to answer my queries and explain everything precisely and with sufficient detail that even myself (a non builder) could understand.

I would recommend Jon’s structural design service with no hesitation.

What can I say, had some real issues with my house and contacted Jon by chance. He was so helpful and even worked over the weekend on the problems. He talked me through in language I understood and was a complete joy, very professional and helpful. Would highly recommend him, and was really good on prices.

Thank you so much Jon, you are fantastic.
