XCN is a specialist engineering and design consultancy supporting complex, high-performance infrastructure projects. We bring engineering, design and digital delivery together under one practice, coordinated from concept through to handover.
Our focus is the work where technical depth and delivery certainty matter most: mission-critical facilities, data centres, and the integrated building systems that keep them running. We are built to be a trusted technical partner, not a generic service provider.
XCN supports the full project lifecycle: concept architecture, multidisciplinary design, BIM-led digital delivery and specialist advisory. We coordinate disciplines under one practice so engineering, design and information delivery move together against one programme.
Building services and power systems engineered for resilience and operational performance.
Building-scale design and the structural and civil engineering that supports it.
The digital thread that ties the practice together, and the independent voice when it matters.
XCN is based on the north coast of Ireland, in the Derry / Donegal region. The location is a deliberate one for an engineering practice supporting projects across the UK and European markets. We work with developers, operators and design teams in the regions where data-centre, mission-critical and infrastructure investment is concentrated.
Our work is technology-led and digitally delivered, which means our regional base is not a constraint. We coordinate, model and deliver remotely as standard, and travel to site or design office where the project benefits from it.
