About Sinclair Johnston and Partners

The Practice

Founded in 1996 by Sinclair Johnston and Derek Glenister, Sinclair Johnston and Partners is a leading firm of Structural Engineering Consultants. Developing high profile projects throughout the UK, the work we do is varied but one aspect all of our projects have in common is that they are challenging and require unique and innovative design paired with bespoke, carefully thought out engineering solutions.

In 2017, Sinclair Johnston & Partners became part of the award-winning international firm, Byrne Looby. Complimentary of one another, the groups combined now offer a more distinct, new strategic offering to business.

The Team

Our skilled Engineers and Technicians lead by our Directors – Mark and Richard, together with our dedicated support staff, provide us with the flexibility to advise on projects of variable scale from small alterations to £100m plus value projects.

Our practice is built on the experience and expertise of our Directors and Senior Engineers and is constantly developed and driven forward by the fresh outlook and skills of our talented Graduate Engineers.
