Bathroom
Narrow idea, for downstairs, perhaps elevate the bath and shower, although the ceiling height may be an issue. This appears narrow, which is what we would like for both bathrooms on the ground floor, 1 serving the 1 bdrm, the other serving the 2 bedroom area. Requires to fire seal between the bathrooms, in case we let out the basement.
