This work is expected to be completed by December 2000. Original entrance now faced in brick and barely recognisable. The bunker is of the semi-sunken variety with steps up to the original entrance blockhouse which contained the decontamination and filter rooms. Apart from the original porch which remains in place, the building has now been clad in brick. The three rooms at this level remain intact though completely stripped of original fittings.
Stairs lead down to the main east - west spine corridor.
At the bottom of the stairs a new entrance has been constructed in the east wall which links to a new 50 yard covered walkway to the admin. The corridor wall itself has been removed and a new curving wall built in its place. The former officers' room at the western end has become the new toilet. The rooms along the northern side of the corridor are still largely intact but completely refurbished with lowered ceilings although it is still possible to identify the plant room, generator room, kitchen, canteen, BT room and balcony. The control room with its well and balcony has been retained and refurbished.
