I think the upper floor is well laid out. But isn't it the case that if the garage is practically part of the house, it then has to comply with the 3 m boundary distance? I'm not sure if this house design would be affected by that.
In s case, no. There must be no living space within the 3 meters.
But the garage may then be a maximum of 9m long and 3m high. And isn’t it higher than 3m with the roof?
No, according to the plan, the right garage is basically only one story and that part probably has only a very flat roof, which does not exceed 3 m in height at the property boundary.
