An Ipswich structural engineering firm is celebrating a 15% rise in turnover last year.

Superstructures, in Queen Street, has also taken on two new staff and invested in a new structural engineering software system, Tekla.

The business was launched by managing director James Potter from his spare bedroom in 2011. Six months laster he was joined by Mark Hayward as director and has grown year-on-year. It now employs around 12 staff, delivering structural designs for a range of projects and sectors in Suffolk and Essex.

“Our best work comes from the clients we work with who understand how we can add value to the project,” said Mr Potter. “Structural designs we delivered last year included Challs International at Hadleigh, Orwells Furniture in Ipswich and The Pines Primary School at Red Lodge.”

The firm adopted the same uncompromising approach, no matter the size of the project, he added.
