Virtus Stockley Park Campus, London

Stockley Park is the United Kingdom’s largest data centre campus, consisting of four state-of-the-art facilities designed for maximum flexibility and efficiency. Once complete, LONDON5, LONDON6, LONDON7 and LONDON8 will also form London’s largest colocation development.

In the fitout of the site’s existing warehouse buildings, internal mezzanine levels were installed to accommodate up to 85 MW of IT power within approximately 35,000 m² of data hall space. This included the provision of associated ancillary and storage rooms.

Three and four-tier gantries were constructed in the service yards to accommodate power and cooling plant, with standby generators located in the service yard outside the site’s gantry.

The campus is supported by a diverse 66 kV power supply which feeds three new 66/11 kV primary substations on campus. Diversely routed 11 kV supplies power the data centre’s three high voltage (HV) switchboards.

Existing office areas have been retained and upgraded to a CAT B fitout for use by Virtus and their tenants. The project scope also included full physical and electronic security.

As design lead NDY worked alongside VIRTUS and, following appointment of the contractor, provided a client monitoring service throughout construction and commissioning. Stockley Park Campus’ features and innovations include:

• Designed in accordance with Uptime Tier III principles.
• Resilient power infrastructure to support critical data centre loads.
• Installation of air-cooled chillers which, in conjunction with elevated chilled water temperatures, maximise free cooling.
• Concurrently maintainable power and cooling systems.
• High pressure water mist system installed throughout for property protection.
• High sensitivity aspirated smoke detection system installed in all IT rooms.

The agile site allows for expansion, with facilities designed to evolve alongside the growing needs of tenants to ensure long-term flexibility and efficiency for businesses.
