A new double-decker Grandstand was built in 1952, one of the last to be based on the template made popular during the 1920s and 30s by prolific football stadium architect Archibald Leitch, with floodlights installed in October 1953. Running the length of the pitch, it had standing room in the first tier, known as the Mayflower Terrace, and wooden seating in the second tier. When a roof was erected on the Lyndhurst side of the ground in 1964, three quarters of the ground were under cover, with all but the second tier of the Grandstand being standing room. In the 1969–70 season seats were added at the back of the Mayflower Terrace, which took the seating capacity to 4,100 and the overall capacity to 40,000. In the late 1970s the pitched roof at the Devonport End of the ground had to be removed for safety reasons. It was replaced in 1984 by a non-pitched structure, leaving just the Barn Park End uncovered.
