An (almost) whole house arrangement with 4 bedrooms & 2.5 baths of use.
There is a large (850+ SF) basement suite with 2 private areas & a private bath. Currently 1 queen bed, & a twin bed.
This level stays a cool constant temperature without AC.
Upstairs would be 3 bedrooms, & full bath.
There is not AC, but each room as a ceiling fan, & there is a 'swamp cooler'. At night we can draw in the 60 degree air.
1/2 bath on the main floor.
