I don’t normally post images at night-time, nor those which contain people, because, like most people who enjoy photographing buildings, people are a distraction to style, design and shape.   But I am breaking this rule in honour of the new Design Museum because everything I had heard about it suggested that it would be a grand 1960s parabolic space filled by a smart, but separate John Pawson interior.   So, I wasn’t expecting the unexpectedly open, triple deck, public atrium surrounded by balconies.   I gather that one of the best features is an accident:  because of health and safety, the main staircase has seats down the middle, making it into an arena for watching people;  and I like the re-use of the original marble from the old Commonwealth Institute:-
