I think HS refers to household shelter, i.e. Bomb shelter? Correct me if I'm wrong. Coz I intend to set that area outside bomb shelter as my dining area too! I'm supposing the fino fan is to cool diners as they have their meals at the dining table?
My floor plan is exactly the same as yours too! After going through your blog, I'm toggling with the idea of hacking the wall between kitchen and service yard. Would u still place your washing machine at the same spot in the service yard? Wondering whether it would look weird if there is no "division" between the washing area (washing machine) and cooking area (kitchen). Any tbloggers out there have good suggestions to this?
