Nice when some people really support each other here :) Nice gable, I always like something like that. About the design (entrance in the east, garden opening to the south) I don't find it that great and can also explain why. The private rooms are too prominent in the entrance area, the auxiliary room hides at the end of a long corridor, which also bends. The opposite is more sensible, especially with regard to possible later physical weaknesses: if someone is not so able or unwell, private rooms “further back” would be better placed so that the more active person can still receive visitors. An alternative, which also has drawbacks but is expandable, serves as a demonstration: the Perfect 95 mirrored and adjusted with stairs. Or simply enter a narrower bungalow floor plan. In principle, very much is feasible and modifiable.
You don’t have an attic then?
The stairs reach the area above the bedrooms and have the storage room, open to the south above the living room as an air space.
