Roof Lounge
A lounge on a roof, where the seating and the view are the point and the weather is a specification problem rather than a feature.
Filed under `lounge` rather than under `outdoor`, and only one of those can be the parent. The lounge-ness is what gets specified - the seating, the lighting, the way it is used - and being outdoors is a condition applied to it. The same call is made on `outdoor_lounge`.
