The original studios were in a two-story building on Quay Street. Bernstein stipulated in 1956 the company needed the bare minimum of studio space and was unwilling to invest in facilities that would rarely be used.[4] This was the reason construction took from 1954 to 1962 and the "save money at all costs" mantra was reflective of Sidney Bernstein's business plan. Facilities expanded and a tower block was built next and studios expanded over time. From time to time, as extra production, rehearsal or office space was temporarily required, various adjacent buildings were annexed. These included warehouses on the opposite side of Water Street, the buildings between Quay Street and New Quay Street and the old school premises directly opposite the tower block.
