ᐅ Unclear exact building size within the building envelope

Hello everyone, a perhaps simple question, since I haven’t found any previous discussion on this topic:

We are currently in the process of buying a plot of land in an established residential area. We plan to build an extension attached to an existing semi-detached house. There is a development plan from 1991 that is still valid. However, I cannot find any dimensions in the plan indicating how large the house can be. It specifies a floor area ratio of 210 sqm (2,260 sq ft) and a site coverage ratio of 105 sqm (1,130 sq ft), but nothing else.

As a layperson, it’s unclear to me how to derive any specific measurements (like 9x10, 9x9, or 11x9 meters) from this information. One option might be to submit a preliminary building inquiry, but we would prefer not to do that at the moment. Are there any other ways to determine the size of the building envelope?

Good luck

2012 does not have a /19, I suspect the gap between the buildings ("2019 West" wouldn’t be an inappropriate term) between Ludwigsburger Street 10/1 and Hartwald Street 1/4 is meant:

That is correctly analyzed and is the right building gap.

Aha! But I have already mentioned that.

According to my research, there is a house on that spot, with an eastern extension, porch or something else, so it’s not suitable for a duplex.


Who is trying to sell you that house? In my opinion, the original builder bought and developed the duplex plot for himself and his single-family home. That is possible. But there must be windows on the side if there is a porch on the east side, right?!

Question: Has anyone reported my post with the BW geodata system (it showed that the western plot of 1/4 is a semi-detached house lot) or also my second post with the picture and had them removed?
The 2012/19 is the matching plot:

2012/19 is the correct parcel number, and the house there has no windows on the west side and was properly built in 1998. Originally, it was indeed planned as a single-family house on one plot.

No, but also not read. Your marked area does not have a building zone to build on, only the edge areas of two building zones.

Okay! Finally some clarity on the location.

No, I haven’t read it either. Your marking doesn’t contain a building zone for construction, only the border areas of two building zones.
How annoying that posts just disappear
