Portakabin was one of the first suppliers on the Olympic site, providing a three-storey building for 400 Olympic Delivery Authority (ODA) staff at Stratford in 2008. This major development accommodated high specification offices, security facilities, and an extensive training centre.

Other buildings supplied by Portakabin included the Command Control Centre, which was later extended with a fourth floor for the Olympic Sponsors Office and a viewing gallery; a welfare centre; security and reception centres; facilities for the Olympic Broadcasting Services London; and production offices and studios for the US broadcaster, NBC. More than 200 single modular buildings and Portaloo toilet and shower blocks were also delivered.

One of the organisations to have hired a London 2012 building from Portakabin is Arla Foods. A three-storey office building located at the Olympic Park was dismantled and reconstructed in Aylesbury to create a 2500m2 two-storey facility to house project, operations and engineering teams involved in construction of a fresh milk dairy.
