foyer building is supported on octagonal reinforced concrete columns, with an undercroft below, and is vee-shaped. The two arms of the vee-shape are linked to the QEH auditorium by cast concrete tubes, reminiscent of a spaceship's docking arrangement. The provision of only two entrances to the auditorium causes congestion and slow exit for audiences. This is also a consequence of the decision to place all the foyer facilities on a single level, even though there is a significant descent to the auditorium entrance level, and steps are required up to the Purcell Room level. The foyer is an irregular shape to accommodate the angle between the axes of Waterloo Bridge and the north-east side of the RFH. A notable feature of the QEH is the interior of the foyer building, with its intimate scale and subtle use of materials, and the terrace overlooking Queen's Walk. The original 1960s cool of this area had been largely lost owing to the intrusion of artificial partitions, to provide smaller areas for various activities by day as well as in the evening, in the 2000s. The extensive foyer was restored during the renovation works of 2016-18, with better integration of access for persons of reduced mobility. The bar area was extended to the south onto part of the external terrace with new glazing to bring more light into the foyer. The main entrance to the foyer is from walkway level near the north end of the terrace of the RFH. To see the intended effect this should be viewed head-on from the north corner of the RFH. The entrance, in brutalist style, is in the form of a horizontal slit in the concrete structure, with six pairs of cast aluminium doors. A smaller entrance is provided at ground level, originally intended to be for visitors set down by car (circulation of traffic under the Waterloo Bridge approach was possible before the Museum of the Moving Image building was constructed in the 1980s) or coming from the car park under the Hayward Gallery. This entrance also appears to have led to the undercroft, but that access is now blocked off. An internal staircase leads to the foyer level from this lower entrance, past the original box office area. Lavatories take up the south-east wall of the foyer building, and are housed in a structure extending out towards the centre access road. The building's appearance works
