What Our Clients Say

"We took a risk with this new company of engineers, to assist us in the design and to produce various drawings for push-wheelchair access to the property. Easy job? Not quite. This property has a very steep front garden. The Zetaqube team were instrumental in spotting how some of our requirements could cause planning refusal and guided us through, what would be more acceptable to our local planning authority. I have no hesitation in recommending these very talented group of engineers, whom we are continuing to work with."
