Well, good morning, everyone, it’s good to see you all here. Welcome to Smith House. Smith House as you may or may not know is one of the oldest residential colleges of the university. [23]As you can see, the building you’re in now which contains this main lounge, the dining room, the recreation room, the kitchen and the offices was part of the original old house, built in the 1840s to be used by the family of George Smith. That’s of course how the house and college got their names. The original house was converted into a residential college for the university in 1940 and since then has continued to be added on to and modernized.
    You’ll notice when you receive your room allocation in a few minutes that your room number either begins with the letter N, S, or W like this one here. The first letter refers to the three wings of the college which come away from this main building. Of course the letters represent the three directions—in this case—north, south and west. Each wing has two floors, and so the next number you see is either one, or in this case, two, and this indicates which floor your room is on. The number after that is your individual room number. So it’s quite simple to find any room by going to the right wing, then floor, and then room number.
    There are only a few rules here at Smith House and we have these rules so that we can all live comfortably together. [24]The most important rule is that there must be no noise after 9 pm. There is also no smoking in the rooms or anywhere inside the college but smoking is permitted on the balconies.
    All meals are served in the dining room. Meal times are listed in your orientation pack. Please read these carefully as meal times cannot be changed and if you arrive late I’m sorry to say you’ll just go hungry.
    If you’re unsure about things, each floor has an elected "floor senior" who is usually a student in their third or fourth year of study who’s been at Smith House for a while. [25]The floor seniors will introduce themselves later today and answer any questions you have. But for now I’m going to hand you over to Peter who is going to give you the orientation packs and the keys. Thanks Peter.
