This project included construction of a three-storey office building, a single-storey data centre (with services & plant located externally at roof level) and an electricity sub-station. The total developed floor area is 5,500 m² on a 2 ha. site. The development included ancillary site works to connect to the existing Grange Castle infrastructural services, and on-site surface water attenuation and pollution protection measures were included to ensure water quality discharge suitable for Salmonid rivers. Downes Associates designed the supporting structure and any associated secondary steel to support the curtain wall system to the data centre, and similarly for the natural stone façade to the office element.
