Technically you could reinforce as long as you can keep a sufficient height or have sufficient space remaining inside ;-) but it might not make sense economically. You could also construct buildings that could withstand any earthquake, but it would not be economical either, building is always a compromise, you won’t typically build a structure that would still remain stable when rotated on its side, but technically it would be possible. What I wanted to say: there will probably be a technical definition of soft storey, while our tag will be yes/no, in reality it will be a gradual property and to map it you will have to set a cutoff somewhere. That’s why there are inherent verifiability problems (even if you knew all the details and dimensions of the structure, material properties, joining details, etc.). Is this something you believe people should survey or should they trust an external source for it?
