I agree with that, but I often wonder whether maintaining a separation for longer periods just leads to a bigger backlog of these topics building up and making it worse when it does happen.
to be honest, having to walk inside to use the bathroom or refill your cup of coffee seems like a nice way to stand up and get the blood flowing again + breathe some fresh air.
I've got a bathroom in my out-building office, too, and a small kitchen with a sink, coffee maker, toaster, fridge, and so on. The limit is money to spend and land area to build on :)
