There are plenty of distractions in an office as well -- chitchat, meetings, poor environment not under your control (e.g. too hot or too cold) and noise. You do need to be disciplined because there's none of the peer pressure that arises from being around other people who are busy working. Additionally, I'd only work from home if living in a big city, in order to combat isolation. In a city you have access to people, whether by interspersing meetings into your day or simply stepping outside, and this combats isolation. I would not enjoy working at home in the suburbs.
