AET Flexible Space have supplied their under floor air conditioning system to a height restricted London refurbishment at 20 Cannon Street, near St Paul’s Cathedral in the heart of London.

Originally constructed in the 1960s, yet situated in a prime location with exceptional views, the building had remained empty since 2008. Working in partnership with Aerium, Developer Allied London purchased the building in 2010 and embarked on an extensive refurbishment to transform the property into modern, state of the art office space

With very limited structural height space, the building was not suitable for a traditional ceiling-based air-conditioning solution. AET’s Flexible Space System was specified by project consultants Mott Macdonald as an alternative. With this approach, the whole plenum under the building’s raised access floor becomes the “duct”, with each floor of the building divided into two zones to match the existing core areas

The AET Flexible Space system is ideal for this type of refurbishment project. By eliminating ceiling based services, it enables older buildings to be equipped with high specification air-conditioning whilst maximising the available floor to ceiling height. Stuart Lyell of Allied London commented "AET’s Flexible Space was the system of first choice for this project. It meets the flexibility demanded for modern city work space, and satisfies many sustainability and energy demands imposed by legislation and socially responsible corporations.”
