Most local teams that I've worked in have mostly been centered around a tool like Slack anyway. I've sat next to people but talked to them more on slack then in person. It really depends on culture. Do most people use a tool like Slack or HipChat?

For working remote, what I found that was the best was making a place in your house or apartment that is the office. Try to do everything in that part and only do work there. It will help you get into a work mode at home.
