To most people, IT is like what is portrayed in The IT Crowd. Having an office in the bowels of your company's building doesn't do much to help shatter stereotypes.
In my career to date, the team that I have worked in that has had the best relationship with the people it served was the first team I was a member of at the BBC. It wasn't by design, but serendipity placed us next door to the tea bar. It is the only IT team I have ever worked in where people would just pop in for a chat (en route to or from a cuppa).
No such footfall when you are in the basement. People only come in when they want something. For the rest of the time we've been out of sight and out of mind. I've been trying a positive spin of "being at the very foundations of the company" but there is a big difference between "at" and "in". Especially when you don't have any windows…
(although there is no danger of that where I'm going, eh?)

But will your new windows have a decent vista?
