I've been to Chicago maybe 11 times since 1997, but took me until 2004 to finally get round to going on an architecture tour.
I'm just going through some old photos and uploading them to Flickr and I found these pictures of an amazing Rem Koolhass building I saw on that tour.
The pictures are from the McCormick Tribune Campus Center which is already pretty special because the original campus was designed by Ludwig Mies van der Rohe.
There's no trickery in that photo above it really is that orange. On the right hand side are a series of orange glass panels which producing that gorgeous effect. The whole building is exciting, colourful, playful and clever.
This picture is of some stairs that are designed to be easy to access by wheelchairs and prams. A simple, elegant way to solve the 'badly designed stuck on ramp after thought' problem.
From certain angles they look like 'normal' stairs. It's a nice visual trick. In this day and age we should be designing buildings with things like access ramps built in automatically. It shouldn't be an after thought or a problem.
The outside of the building has pictures of famous architects. When you get closer the pictures are made up of great little graphics like this.
Fantastic. A few more pictures in this Flickr set here.
