St Cecilia’s Hall, University of Edinburgh

Harley Haddow provided full MEP design services for the refurbishment and new extension, incorporating an advanced environmental conditioning system to protect the world-class collection of historic musical instruments. The performance hall features a bespoke displacement air conditioning system, designed to provide low-velocity, low-noise ventilation while maintaining precise temperature and humidity control. Acoustic detailing and coordination with the Acoustic Consultant ensured excellent performance quality. The building achieved a highly efficient environmental system with minimal energy consumption and is on target for BREEAM ‘Very Good’.

Collaboration was fundamental to the project’s success. Harley Haddow worked closely with the architect, acoustic consultants and the University of Edinburgh team to deliver a coordinated design that respected the building’s heritage while meeting modern performance standards. The entire project was modelled in 3D BIM, allowing the team to identify and resolve coordination issues early in the design process, ensuring a smooth construction phase and high-quality outcomes.

Working within a restricted heritage site in Edinburgh’s Old Town required careful planning and coordination. The integration of new services within the existing building fabric demanded innovative solutions sympathetic to the architecture. Ease of maintenance was also a key priority, with plant designed in unitary arrangements to simplify installation and future replacement without craneage. By addressing these challenges proactively, Harley Haddow delivered an efficient, discreet and maintainable MEP design that complements the building’s historic and acoustic integrity.
