The practice has extensive experience in structural engineering design, with a particular focus on building structures. Although our work spans all major building-types, the majority lies within the commercial, residential and educational sectors.


We embark on each project in an energetic, collaborative and proactive manner, with directors closely involved in all aspects from concept through to construction. The firm prides itself on delivering efficient, carefully-considered designs and always strives to use its client’s money wisely.


We have particular experience of working on urban sites with unique and complex constraints, considering all phases of construction from demolition and temporary works through to completion.


We are passionate about design and the built environment, and take the office abroad each summer to explore the architecture and buildings of European cities. Technical staff meet regularly in support of their own continuing professional development, and project-related training is part of the everyday working environment.


Heyne Tillett Steel strive to ensure all outputs are of the highest standard, involving regular Director reviews thorough out the lifetime of a project. We have a rigorous internal Quality Assurance system which is accredited by BSI to ISO 9001:2008.


Above all Heyne Tillett Steel are structural engineers; hard-working and passionate about what we do and the buildings we help create.
