Heritage & Bespoke Structural Design
Structural design for listed buildings, conservation areas and ambitious architecture, where safety and sensitivity have to work together.

Heritage & Bespoke Structural Design
Heritage and high-end architectural projects need structural design that respects both the engineering challenge and the wider design intent. Our role is to support the building concept, the purpose of the change and the practical requirements of safe construction, without imposing on the character of the building.
Specialist and bespoke work calls for an elevated level of competence, particularly where a project falls outside standard design routes: unusual geometry, long spans, cantilevers, non-standard materials, retained facades, complex alterations or ambitious architecture. Protected structures, including listed buildings and conservation areas, often need interventions that are discreet, sympathetic and carefully coordinated.
Why Clients Trust This Service
Where Safety and Sensitivity Meet
We have a long, tried and tested relationship with projects of this nature, and we recognise that safety and sensitivity have to work together. The aim is to protect the character, value and performance of a building while enabling repair, alteration or a contemporary extension.
How We Help
Applied Examples
Historic Timber and Fabric
Strengthening historic timber floors while minimising visual impact and avoiding the unnecessary removal of original fabric.
Concealed Interventions
Introducing concealed steelwork into listed masonry to support new openings or internal reconfiguration, kept discreetly out of sight.
Old Meets New
Designing contemporary extensions to traditional buildings, where the junction between old and new needs careful movement and load-transfer thinking.

Our Approach
How We Work
01
Understand
We begin by understanding the building, the brief and the constraints, working from drawings, photographs and, where it helps, a visit to site.
02
Design
We develop a safe, buildable solution, sizing the structure and resolving the load path, materials and the key connections.
03
Coordinate
We coordinate with the architect, surveyor, contractor and Building Control so the design fits the wider project and can be approved.
04
Support
We stay available through construction, answering queries and revising the design where site discoveries or changes call for it.
Questions
Frequently Asked Questions
Can structural alterations be made to listed buildings?
Alterations to listed buildings are often possible, but they call for careful design, clear justification and coordination with the conservation approach. We design interventions that are sympathetic and defensible when consent is sought.
Do you work with conservation architects and officers?
Heritage projects are strongest when the architect, engineer, conservation officer and wider team coordinate from the outset, and we are used to working in that setting.
Can modern materials be used in older buildings?
Modern materials can sometimes be introduced, but compatibility, movement, moisture and visual impact all have to be considered, and significant proposals are discussed with the relevant statutory bodies.
Can you design concealed steel in a listed property?
Introducing hidden steelwork to support openings or reconfiguration is a common way to enable change while protecting the historic appearance of a building.
Do you provide the structural information needed for listed building consent?
We provide the design information, calculations and justification a heritage scheme typically needs, coordinated with the conservation strategy.
