Really Cool mate!!! Really!!
Mate I seriously love the use of the cabinet door to close the space off. I've been designing a host of home designs of late that similarly utilise joinery to create room division. It's not something at all common here is Australia and I seriously don't understand why! We always build a wall and then the cabinetry to it rather than letting the cabinet become the divide, even if the cabinet is single side facing it can still be finished on the reverse side as a feature to the room!
You do some great solutions mate!
