For a place 4x4 Ama, what should the walls of a dwelling be to obligate the place in Mezuzah:
- How many walls are required?
- Can they be partially or completely transparent?
- What height should they be?
- Are workarounds that count as Mechitzah (Lovud, Gud Asik) good as walls?
- Should there be a roof?
- How much of the space should the roof cover?
- How far can the roof be from the walls?
