How we can help

By providing expert structural engineering consulting services ranging from structural surveys and defects assessments, conceptual advice through to detail design and support during the construction stage of a project, and everything in between.

Structural Surveys and Appraisals

Clear, concise and useful reporting, using a wealth of knowledge and experience to investigate and appraise an existing structure, to determine defects and causes, make recommendations and provide remediation solutions.

Feasibility Studies

Identifying suitable and creative structural techniques, to maximise the development potential of a scheme and adding significant value.

Structural Concept Advice

Contributing to the broader concept design, to de-risk a project, enabling firmer and earlier cost-certainty and a smoother design and coordination process.

Support for Planning, Licences to Alter, and Listed Building Consents

Applying specific expertise and knowledge of the behaviour of traditional buildings. Presenting clear and well-considered solutions and techniques that respect the historic value and sensitivity of the original building fabric, whilst realising the ambition of the architectural concept.


Peer Reviews and Expert Witness

Impartial review of others’ structural engineering proposals, supporting a collaborative approach to finding optimised solutions to challenging schemes.
