I have chosen! My dissertation topic is now going to be the Nottingham Contemporary. It is an art gallery in Nottingham, designed by Caruso St John. They are an East London based architecture firm and it will be nice to discover how they've used their knowledge to respond to the awkward site that they have built the museum on it.
As it was built in an area that used to produce lace, homage is paid on the facade with concrete tiles that have been caste with a lace pattern.
Check the Museum out! pretty neat.
