West End Roof

To London to visit colleagues temporarily transported to the bright lights and smoke.
The building they are in is fascinating, the outside is old and aged and very well looked after. The guys work in an area behind this façade, approached via a glass staircase and glass floor in an atrium created between two old buildings by putting a glass roof over the void. It is really light and airy; the work place is very pleasant, unlike their current task.
This roof is on the building next to theirs.
