Is the blower door test included in the energy saving ordinance item? Otherwise, the basement or some kind of storage room elsewhere would definitely not be bad. Are you sure a desk fits sensibly in the dressing room? What kind of area calculations are these? Living area? Otherwise, the children's rooms are quite small. Kitchen, dining, and living areas are at least, according to the area specifications, exactly the other way around. Just under 16 m² living room (obviously, you can't see it so flat since it's open) is borderline.
