85 Fleet Street | London – UK. Flexibility with Ease of Installation in a Multi-Use Building

Applications: Control of air handling units, cooling and heating systems and monitoring of the level of carbon dioxide via C02 sensors
Number/Type of Building: 75,000 m2
Consulting Engineer: Arup & Partners


The newly refurbished building at 85 Fleet Street, London is a speculative development by UBS Global Asset Management UK Ltd. The building comprises retail units at ground floor level and around 7,600m² (81,810 sq ft) of office space on seven storeys. Two basement levels provide additional plant room space. Formerly the UK headquarters of Reuters, the building has a listed façade, which has been retained during the extensive refurbishment. The constraints imposed by the listed status of the building presented building services consultants AWA with a number of challenges.

Throughout the design, flexibility to accommodate future tenants’ requirements was a key factor. To that end, the services have been configured so the space on each floor can be let by floor, half floor or quarter floors.

“One of the reasons for choosing Cylon was their use of an open protocol, which makes it very easy to interface with other control systems”

Andy West, AWA Consulting
