“I have worked with Mark and the Sigma team for many years. We have been involved in multiple different fast track commercial projects and high end residential works. I have always found Mark and his team to be totally professional; their detailed design is second to none and they have always delivered on each project with complete satisfaction."

"We have had an ongoing partnership with Sigma that started in 2017.
Throughout this time it’s been very clear that their approach to design has commission-ability as a key consideration - As such they repeatedly produce high quality and commission-able systems that leave both ourselves and the client extremely satisfied."
