Sir Denys Lasdun created a radical new headquarters for the Royal college of Physicians 50 years ago. Unlike anything else in the classical, verdant green surroundings of Regent’s Park, his building was bold, restrained and unashamedly modern. He is also the architect responsible for one of my other favourite of all London buildings, the National theatre, Southbank.
Lasdun’s building is comprised of three contrasting materials, expressing the form of the building and defining the three distinct zones. The grand, ceremonial areas are clad in off-white mosaic, appearing to float above the lower administrative areas constructed from dark blue engineering bricks. Concrete was used for the fire escape and functional, hard-working parts of the building.
This extraordinary building is the subject of a current exhibition, now until 13 February 2015.

Didn’t know any of those so thanks for sharing them! What did you think of these?
a pleasure! this building really is special, particularly given it’s surroundings. I’ve been inside for a few functions, in fact the American Institute of Architecture held their awards there a few years ago. The staircase is a knock out.. Great to hear from you Virgina.
