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

You’re not the first to wonder about that. And in an hour, these posts won’t be visible anymore either.

The 2012/19 is the suitable plot:
... and has been renumbered / resized. There is probably also an amendment to the shown development plan, which may provide more detailed information about the building envelope sizes.

Here is the building envelope shown on the cadastral map. Dimensions approximately 9.5m (31 feet) * plot width minus 3m (approximately 9m / 30 feet).

Attachment too late. What is the actual size of the plot? I measured 12 by 22.5 meters (39 by 74 feet).

The safest method is to measure the neighboring house on the property. You probably already know the width of the plot. My result differs by only 4 m² (43 sq ft).

That seems to fit very well with the possibly rounded values.
