I just assume the layout is similar to a real business that's also used as a homestead; shop and shop floor is located on the ground floor with a door heading upstairs to the living area, which I assume from the background CGs is a 2-bedroom apartment consisting of a living room connecting to the bedrooms, and a bathroom. Looks like the living room and Kashou's room has a small balcony.

You might be best off waiting until the anime airs or watching the OVA which might provide some insight into the layout, or taking a guess by looking up the background CGs over in the image gallery and getting some inspiration from small businesses which have people living above them; they're usually accessed by a staircase somewhere around the ground floor.
