This amazing structure outside Guy's Hospital was designed by Heatherwick Studios.  It sits on the approach to the hospital which Heatherwicks describe as, ".. . confused and congested resulting in the main entrance being hard to find."  They add that, "... A range of problems were identified: Great Maze Pond Road being used as a cut-through for cars; narrow pavements with high volumes of pedestrians; no designated drop-offs for patients or visitors; no secure cycle storage; the unsightly boiler house adjacent to the main entrance suffering from decay; the charity shop for the Friends of Guy’s in a state of poor repair."

So in 2005 they were commissioned to address these issues.  They say that, "... Much of the scheme consists of functional, pragmatic moves, which create space for a focal point, in this instance provided by Boiler Suit – a bespoke tiled cladding system wrapping around the boiler house.  Boiler Suit is fabricated from high grade stainless steel frames, with braid woven through as the “warp”. ....

... The 108 tiles are geometrically identical, with 17 variants required to accommodate specific junctions. The tiles are a secondary façade system that is demountable and allows the machinery to vent through, whilst framed reveals shade the large windows on the south façade to reduce solar gain."
