Conservation & Heritage

Structural engineering for listed and historic buildings, balancing the original fabric with the loads and uses of today.

Conservation & Heritage

What we cover.

Older and listed structures need an approach that respects how they were built. We assess timber, masonry and iron structures, work with conservation officers and specify repairs that keep the historic fabric intact while making the building safe and usable.

How we work

Can a listed building be altered structurally?

Often yes, with the right approvals. We assess the existing structure, design sympathetic interventions and provide the structural evidence needed for listed building consent, working alongside the conservation officer and architect.

  • Sympathetic repair of original fabric
  • Timber, masonry and iron structures
  • Evidence for listed building consent
  • Coordination with conservation officers

Standards & codes

The codes behind conservation & heritage.

Eurocodes 0-9 & UK National Annexes

BS EN 1990 through BS EN 1999 govern the basis of design, actions, and the design of concrete, steel, timber, masonry and aluminium structures. Every calculation we issue references the relevant Eurocode part and its UK National Annex, and states which parts were applied.

Analysis, design & drafting software

Structural analysis and design in Tekla Tedds and Tekla Structural Designer, with Autodesk Robot, CSC Fastrak, CSC Portal Frame, MasterSeries and Hilti Profis used where a scheme suits them. Drawing production in AutoCAD, and modelling in Autodesk Revit where a project is delivered in BIM. Output is issued as readable calculations rather than raw software printouts, so a checker or a building control officer can follow the reasoning.

Approved Document A (Structure)

The Building Regulations requirement your local authority Building Control checks against. Our calculations and drawings are prepared to demonstrate compliance so your submission is accepted without back-and-forth.

Professional indemnity insured

Every report and calculation package is backed by professional indemnity cover, which is what lets a lender, Building Control or another engineer rely on it.

Process

From enquiry to sign-off.

1

Enquiry

Send drawings or describe the problem. We confirm the scope, the deliverables and a target timescale.

2

Information

We agree the survey, drawings or data we need and any site access required.

3

Engineering

Design, calculation or assessment to the relevant Eurocodes and UK National Annex.

4

Issue

A clear, defensible report or set of calculations, with assumptions and limitations stated.

Selected work

Real structures, surveyed and engineered.

Questions

Common questions

Do you work with conservation officers?

Yes. We provide the structural assessments and repair specifications that support consent and address the concerns raised by conservation officers.

Can you assess a historic timber roof or floor?

We assess historic timber, masonry and iron structures, identify decay or overload and specify repairs that retain as much original material as possible.

Do you handle full heritage refurbishments?

We provide the structural engineering for heritage refurbishment, from initial assessment through to repair details and construction-phase support.
