St Nicholas Cathedral

Harley Haddow provided sensitive civil and structural engineering interventions tailored to the cathedral’s heritage context. This included detailed assessments of stonework and the existing building fabric, evaluation of structural interfaces between old and new elements, and monitoring and addressing movement within the historic structure. The team supported the transformation of internal spaces by enabling new visitor facilities—such as a café, shop and interpretation zones—while ensuring all interventions respected the cathedral’s historic character. External works included improved landscaping, pathways, seating areas and integrated public realm enhancements.

The project required close collaboration with the client, heritage bodies, architects, and church representatives. Regular coordination ensured all design decisions aligned with conservation requirements, funding criteria, and the cathedral’s long-term community goals. Stakeholder engagement was central to shaping accessible, welcoming spaces that could support a range of cultural and community activities.

Key challenges included maintaining the structural integrity of the historic fabric while adapting the cathedral for modern use, managing complex funding arrangements from the Heritage Lottery Fund and Church bodies, and integrating new facilities discreetly within a highly sensitive heritage setting. Landscaping interventions also required careful design to unify adjacent public realm areas and enhance the cathedral’s presence within the city.
