In 1977, Clydebank, a relatively small club, were promoted to the Scottish Premier Division. At that time, the grounds of clubs in Britain were required to comply with the Safety of Sports Grounds Act if their capacity was above 10,000. Clydebank, faced with a large bill to ensure compliance, decided to reduce the capacity of Kilbowie Park to 9,950 by bolting wooden bench seating to their terraces, which were open to the elements. Kilbowie thereby became the first all-seater ground in Britain, albeit as a response to an unforeseen problem rather than a long-term plan.
