1973 saw the completion of the roof around the circumference of the stadium, along with the addition of 5,500 seats to the Scoreboard End and the replacement of the old manual scoreboard with an electronic one in the north-east corner. Then, in 1975, a £3 million expansion was begun, starting with the addition of the Executive Suite to the Main Stand. The suite's restaurant overlooked the pitch, but the view was still obstructed by the roof pillars. Therefore, in kind with the roofs of the United Road Stand and the Scoreboard End, the Main Stand roof was replaced with a cantilever design. The Executive Suite and cantilever roof were then extended to the full length of the stand, allowing for the relocation of the club offices from the south-east corner to the Main Stand. The south-east quadrant was then removed and replaced in 1985 with a seated section bringing the total seating capacity of the stadium to 25,686 (56,385 overall). The completion of the cantilever roof around three sides of the stadium allowed for the replacement of the old floodlight pylons, and the attachment of a row of floodlights around the inner rim of the roof in 1987.
