The 1970s saw the opening of Bletchley Leisure Centre which was the first local authority leisure pool housed within a glazed pyramid. The innovative design which incorporated a freeform leisure pool with real palm trees caused a quantum shift in the perception of public sports and leisure provision and heralded a new wave of exciting leisure pools which boosted swimming numbers in the UK. The buildings pyramidal shape became a symbol for the new Milton Keynes Township and was featured in a sports architecture exhibition in the Museum of Modern Art in New York in 1977 - the firm had established its international reputation.
During this period the practice developed the corporate design identity for the entire £300 million Tyne and Wear Passenger Transport System which adopted a kit of parts design guide using a small palette of materials and colours to produce a memorable character. This work led to the subsequent appointment of FaulknerBrowns Architects for the refurbishment and interior design of four stations for the London Underground system.
Continuing expansion of work within the civic offices, universities and sports sectors enabled the practice to grow in size to around forty. Turning innovative ideas into reality was at the heart of the practice and resulted in the firm contributing to the development of a number of design management tools such as co-ordinated production information (CPI), RIBA Plan of Works and becoming one of the founding partners of the National Building Specification (NBS) which is still used today by most architectural practices.
