Going to echo the main point I do on all remote threads - it needs to be inherent to the culture. Things can't be decided by the water-cooler if you have people who are working remotely - you need, ideally, to be "remote first" even if you have a physical space. We have offices, but every employee can work remotely (realistically, 2/3 days a week at least), and with the spread of offices and team members, working collaboratively is a native thing. If it was only a few people though, you start forgetting to put a Skype link in a meeting here, not having resources to share ahead of calls there, and making decisions in the corridors all over the place. Have an office, sure, but behaviours need to be the same whether you're sitting next to someone, or hundreds of miles away.
