The Canadian Parliament Building has sat unchanged for over a century. The building has a very old look to it, mimicking the parliamentary and royal buildings in the UK. Recently, however, a plan to build a $42 million glass roof over parliament was approved. The glass roof will be placed over the House of Commons and bring Canada's Parliament into the 21st Century.
I for one applaud the new design; there's no reason to harp about the preservation of the building for historical purposes. The building is still in use, and should suit it's purposes long into the future!
Cheers to Canadian innovation!
