I'd not recommend you to study there.
I am applying for Master's degree of Architecture in England, and I have done some research about it. Recently, architecture at Cambridge has been downsized, and will not worthy a try. I think you also have heard about it that it nearly got canceled in 2006 -- that it, there would be no architecture in Cambridge any more -- thought, still it stays luckily. If you are interested in the philosophy side of architecture instead of the design practice, maybe Cambridge is good for you. Otherwise, you can always go for UCL, Bath, and etc.
Good luck.
