Layouts and such, architecture. Atmosphere, interior design. Though there’s a lot of cross over tasks for both. You can always hire an architect to sign the required papers. If making custom furniture then furniture/industrial design; or at least have some knowledge of how furniture is made so you can make plans to be outsourced correctly. Doing all of it I feel the atmosphere and layout is 70% of the project, the other 30% is project management during construction phase, knowing the right contacts and such.
