one of the more wonderful modernist ideals was modularity. It's a post industrial ideal to be able to manufacture everything cheaply and quickly. this allowed Crystal palace in London to be built in record time but it was the modernists who grappled with finding the true aesthetic of manufactured and modular....it's just a shame it cost the earth but maybe in some small twist of fate the thing which can help us now is once again modularity with a greener hand? I don't know maybe?
