I visited the
Pompidou Center in 83 and I thought it was really cool. The reason it looks so "unfinished" is because instead of having all the ductwork inside the building, it's on the outside. All the pipes are color-coded.
- blue for air
- green for fluids
- yellow for electrical cables
- red for elevators and fire extinguishers
Because all the ductwork is on the outside, the interior is much more spacious than a typical building. Obviously, the design is not to everyone's taste, but for a building designed to be artistically unique, it totally works for me.
