Nonsense, someone here can't read development plans.
150 sqm should not be exceeded due to construction costs.
Unfortunately, 120 sqm per floor (!) is already almost the minimum to afford a space eater like a straight staircase. I wouldn’t even consider something like that below 12 (with a recessed belly also 10.5) meters house width.
The setback distance of the garage is absolutely unnecessary.
The bedroom in #8 (left) does not work. You’d need a robot like in high-bay warehouses to remove the sleepers from their beds.
