There is no one size fits all solution...for me personally, I require a mix of social and private time to maximize my productivity. Working from home half the time, and working in the other half tends to be best...For those who want to talk/meet, knowing I'm only there at certain makes them more likely to think twice about prioritizing meeting time. Also, the quiet of home and lack of distractions (no giggling coworkers or visitors to the office) leads to the best writing/thinking.

You just have to know how you work best, and hope your company can support it. If you're a startup, be flexible about optimizing workers' time...
