The coworking space where I work took the exact opposite approach. For each new location they hire an artist and let him go wild on the decoration, they have an in-house team of architects to make it happen. It makes for interesting social dynamics since people with similar taste tend to gather at the same place, and the variety also encourage people to move location to see something different. But it has another more pragmatic benefit for the coworking company; the locations will not go out of style at the same time and so they don’t have to renovate all locations simultaneously.
