That’s a very interesting video. But I still have to ask WHY is it ok for an office to lack the lighting and escape routes when the same is not ok for residential areas (which was the main reason given)? It makes no sense to me. Water and sewage poses no problem because large office buildings have to account for mutiple toilets on each floor. Electricity is also a non issue (I’d argue electricity usage would vastly decrease when coverted). That just leaves shared air circulation and conditioning which also shouldn’t be an issue since it would just be maintained through the landlord (and could even be cheaper for the individual since they don’t have to pay for their own systems but just a flat fee on the rent).
I honestly don’t know, but I probably wouldn’t want to live in an place with no access to the outside at all, not even a window.
