These are my highlights...
A re-issue by Knoll International of Marcel Breuer's classic B3 (Wassily) Chair (1925):
Ceiling Light (2006) by Luc Merx:
Chandelier Spectacle (2006) by Stuart Haygarth:
This is made of many different NHS glasses and frames that Haygarth had collected.
In the photo below (from left to right): the iconic K6 Telephone Kiosk by Giles Gilbert Scott, a 1960's Savile Row suit by (the wonderfully named) Tommy Nutter, a 1960's Mary Quant mini-dress and a scale model of the HSBC HQ (in Hong Kong) designed by Norman Foster and Partners (1979-86)
The aptly named Looksoflat prototype lamp (2010) by Stefan Geisbauer (that uses a thin LED light):
There is also a Terence Conran exhibition on the floor below that is worth visiting.
