To stay at home and work on your own computer can make you feel quite comfortable, for you can do whatever you want without any restrictions imposed on your schedule or even workload. However, I think people need to distinguish between work and normal life, and several distinctive features of working consist of efficiency and communication, which cannot be realized when working alone at home.
In the recognition that efficiency is one important goal for which we always strive, nobody would deny the importance of working in your company's office. We usually seek for an efficient working condition, and that is why a company with strict rules is designed. The goal of a company is to minimize its costs and thus the time cost of its employees are one important concern. 
Apart from efficiency, timely and face-to-face communication is another key factor to achieve a good result in our work.
Last but not least, the distinction between work and common life can also help us enjoy a better life when we are at home. It seems to be a little bit against our intuition, but the fact turns out that those who closely combine their work and life- that is, working at home-often complain about that they are still entangled in the chaos of working when others have fell asleep. To work at home may ease your strain compared to working at your company, but the drawback is that you always fail to finish tasks before the deadline and the constant extension of your working time. Therefore, working at home has an inevitably negative impact on your daily life.
