Maybe, through those spaces, there is a small sort of 'den' which will house a sink, BBQ, cupboards. Essentially everything you need for a small kitchen. Then there's that small roof, which could be a place to leave plates.
For example, somebody cooking in the kitchen area, they could just leave prepered meals on a stand underneath that small roof area?
I don't really know how to word what I think!! I hope you understand me.
Certainly interesting though, well spotted telefan, I also agree with you, this IS looking like the best house for a good few years
