Stuart has gained an access all areas tour of the Leadenhall building.

It’s a long way down from the 42nd floor.

Outside there’s a lovely view; St Pauls looks tiny.

The plant rooms with all the generators are immaculately maintained.

They also have some of the best views in London.

The vehicle lifts in the basement are supposed to be able to carry 26tons! The righthand one is temporarily out of action; perhaps it couldn’t quite cope with Stuart.

Top of the Gerkhin!
