As much as I love architecture, the next few years are going to very difficult for the profession. Most companies are not currently taking on many students either Part 1 or Part 2, little prospect of any significant public sector work for the foreseeable future and insufficient confidence in the private sector to kick-start commercial development, all a bit bleak but overseas prospects much brighter.
However, lots of places do p/t degree and post grad architecture courses and if you were to start now, hopefully it might be picking up again in the UK by the time you were fully qualified.
