CITY OF LONDON EC3 - P & O BUILDING
Built in 1969, with 15 storeys above ground and three below, this building was considered at the time to be one of the most complex glass-fronted structures in England.
It was extensively damaged by a Provisional Irish Republican Army bomb attack in 1992, and subsequently had to be reclad. Now it is being demolished to make way for a much taller, 48-storey tower, destined to be the tallest building in the City until the completion of the neighbouring Bishopsgate Tower. The distinctive wedge-shaped profile of the new building has already led to it being nicknamed the Cheese Grater. The project is costing £286 million.
The demolition procedure for the old building is unusual, being conducted from the bottom upwards, rather than the other way round, leaving the building’s concrete core exposed. This is because of the unique way in which the building was constructed: the floors are supported by a beam hanging from the roof rather than being supported by columns from the ground.
