We have extensive experience in the structural design of new buildings of all types. We also specialise in structural surveys of existing buildings and the design of alterations and extensions to existing structures.

Our project experience ranges from home alterations and residential barn conversions to historic building conservation and industrial developments. Our structural designs encompass a wide range of construction materials in order to produce economical and safe design solutions to meet the needs of the brief. We achieve this with the help of state of the art design and analysis software where necessary, and with careful attention to detail.

We are also an Approved Certifier under the Structural Engineers Registration Scheme for Scotland enabling us to ensure all aspects of the design meet Scottish Buildings Regulations.
