A site plan of the shiny-new BRENT CROSS CENTRE. Encompassing 799,900 lettable square feet and 75 shops, the facility would revolutionize retail in the UK. The Upper Ground Floor (or second level) is depicted here. The mall's parking area could accommodate 3,500 autos. This would be expanded to 5,500, with a multi-storey car park. This structure was completed in 1985, but demolished just 9 years later. 

A vintage view of the mall's Central Court, fountain and water garden. The dome overhead was decorated with coloured glass inserts. It was sealed from the outside, with no windows. In fact, the original mall had little -if any- natural lighting.
