ᐅ Development Plan Building Envelope

Good evening,
since I have already seen several development plans, I am wondering what the “Z” might mean!?

WA – general residential area OK
I – single-story construction OK
o – open building layout OK
site coverage ratio – 0.3 OK
floor area ratio – 0.5 OK

but what does “Z” mean – ?

No, unfortunately, I don’t have the legend for the development plan at hand
and there is nothing about it in the zoning regulations either.

It might refer to the roof. A hip roof.
Is this related to one of your other inquiries?
Are you familiar with the plot of land? Then you can find out if that is the case.

No, a tent roof is TR.

But I don’t know either. There is no information about Z available online.

Speculaas: Perhaps the "Z"—similar to floor area ratio and plot ratio—refers to the value "o" next to it for open construction and is meant to indicate the permitted type of development? @Escroda might know more about this.

No. It is a different plot of land.
