If that's true my first priority would be to have either a house big enough for a separate office or even enough land to have an office shack or floor above my garage. A separate work cabin that involves a commute doesn't make a lot of sense to me.
It's okay if you just didn't go into detail but I don't see anything about a kitchen, and the remote location kinda implies there isn't anywhere nearby to get food. Nothing nearby is totally okay as long as I have somewhere to make or at least reheat food. Firepits aren't enough if they're the only method of cooking because it can be pretty gnarly outside and I don't want making lunch every day to involve making a fire, dealing with rain, and getting smoky.
