Hi!
I am a Natural Sciences student, specifically studying Maths and Computer Science.
In terms of location, Butler is about a 10 minute walk from the Science Site (Where most lectures and tutorials are usually held). From the centre of town, it's about a 20 minute walk. Overall, it's not the most central college, but not unreasonably far from anything. There's also a bus which costs £1 for the day, which runs from Butler to the science site, and the centre of town.
In terms of pricing, all of Durham's colleges have standardised accommodation costs. However, the one advantage of Butler is that all the rooms are exactly the same (Self Catered, en-suite, single bed, not shared). This combination makes it one of the most affordable colleges in Durham IMO, as catered colleges are way overpriced. Day-to-day costs are very affordable. Our JCR levy is comparatively lower than other hill colleges. Our formals are a reasonable price considering we're not paying for food in the first place.
In terms of the societies, there is everything ranging from sports (football, hockey, rugby, darts, pool, badminton, tennis, squash, ultimate frisbee, lacrosse and rowing, just off the top of my head!), musical societies like our Jazz band, Soul Band, and Folk band. We have more weird, niche ones, like Baking Soc, Stargazing soc, and Meme Soc, as well as some more relaxing societies like Tabletop Games Society, or Gaming society. There are also committees if you want to contribute to the college (I personally help out with Tech Comm, who helps to set up for bands in the bar, and do lighting/sound for performances).
Anyway. My favourite part of Butler? That's actually quite a tricky one
Probably, the very get-up-and-go #GetInvolved attitude that everyone seems to have here. A massive amount of people here take part in societies etc, and come on the socials and events. It's really nice just to have such a great, inclusive group of people here.
