Architects are primarily interested in being "different" enough from the competition, to build a reputation for innovation, this being the best means of getting those Oh so lucrative public works contracts.
Their results do tend, however, to be puzzling at times.
Les Barker summed it up pretty neatly, I thought.
Last night I dreamed I had a dream, in cold, electric blue, I dreamed I met the architect who puts fittings in the loo, And I found that he could do the thing the rest of us can't do, Press down the tap with one hand, WHILE WASHING THE OTHER TWO.
