What we do
End-to-end engineering, from concept to commissioning
Six disciplines under one roof, coordinated through a single BIM model so structural, civil, and building-services decisions stay in lock-step.
Civil Engineering
Drainage, earthworks, highways, and site infrastructure designed for resilience, adoption, and long service life.
Learn moreMEP Engineering
Mechanical, electrical, and public-health services coordinated for comfort, low energy, and minimal clash.
Learn moreInspections & Surveys
Structural condition surveys, defect diagnosis, and load assessments for existing and heritage buildings.
Learn moreProject Management
Programme, cost, and risk control from feasibility to handover, keeping every discipline aligned to the brief.
Learn moreBIM & Digital
Federated 3D models, clash detection, and data-rich deliverables that cut waste and de-risk the build.

Sectors
Where our engineering goes to work
We bring the same analytical discipline to a footbridge and a forty-storey tower. These are the sectors we know best.
Commercial & Mixed-Use
Office towers, retail, and podium developments with complex transfer structures.
Residential
From RC-frame apartment blocks to large-scale housing and modular schemes.
Bridges & Highways
Road, rail, and pedestrian crossings designed for the long haul.
Industrial & Energy
Warehouses, plant rooms, substations, and renewable-energy structures.
Education & Health
Schools, laboratories, and hospitals where compliance is non-negotiable.
Heritage & Retrofit
Sensitive strengthening and reuse of listed and existing structures.
Why Solidframe
Designs you can build, defend, and stand behind
Engineering is only as good as the structure it produces on site. We design for the contractor, not just the calculation — and we stay accountable through to commissioning.
Chartered engineers on every job
Work is led and signed by CEng members of ICE and IStructE — never delegated to unsupervised juniors.
Buildability built in
We engage contractors early so connections, tolerances, and sequencing work in the real world.
Lower carbon by design
Material-efficient schemes and whole-life carbon assessment cut both cost and embodied emissions.
How we work
A disciplined path from brief to handover
A clear, four-stage method aligned with the RIBA Plan of Work that keeps design coordinated, compliant, and on programme.
Brief & Feasibility
We interrogate loads, constraints, and ground conditions to set out viable structural options and budgets.
Analysis & Design
Schemes are modelled and analysed to Eurocodes, optimised for material, cost, and carbon.
Detailing & Approvals
We produce coordinated drawings and calculations, securing building-control and warranty sign-off.
Construction Support
Site inspections, RFIs, and as-built records keep the structure true to design through to commissioning.
Client voices
What clients say about working with us
"Solidframe found a transfer-structure solution that saved us a full storey of steel. The detailing was flawless and building control signed off first time."
"On a live, occupied hospital their condition surveys were meticulous. We trusted every load assessment they put their name to."
"As main contractor I judge engineers by their drawings on site. Solidframe's were the clearest we've built from in years — almost no RFIs."
