I joined the University Library (£30 a year for alumni) for that purpose. The maths and natural sciences sections are almost always deserted (except when it's an open day and there's a gaggle of excited sixth-formers wandering through) and anyone who is there is working in a very focused quiet way (unlike the humanities section which is a bit of a bear pit, very noisy, smells of fries and has empty pizza boxes left every where). It is perfect for getting things done, when I have that sort of thing to do, often in a third of the time it would take me working from home. I like to be away before 4pm when the buses and roads start to get busy and that galvanises me like you can't imagine :) For networking, I hang around places like the Phoenix, where we had SteemCampUK. They have wifi and you can have your laptop out as if you are working and in no time at all, someone will stop by to say hello and the laptop gets moved out of the way. There are plans for a new co-working space - the big benefit of that would be access to a quality printer, which I do occasionally need ... look forward to the further adventures ...
