I can do that at the place I'm at now and I honestly thought I'd get less done keep looking at the telly or having coffees, but get tonnes more done as no distractions that I get in the office. Don't do it often but it's very productive.Working from home a day a week leads to a great improvement in your quality of life in my experience. You can fit jobs around work and in practice I find you tend to start earlier and work a bit later because you can do lots of things in parallel.
