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

That fits quite well with the possibly rounded values.The 12-meter (39 feet) width is definitely correct. At 22.3 meters (73 feet), you already have 267.6 m² (2880 ft²).12 m (39 feet) minus 3 m (10 feet) means the building area is definitely 9 m (30 feet) wide.
I’m not sure why the building area would have such an awkward dimension. But in my opinion, there is an obligation to extend with the same geometry as the neighbors anyway. So you just need to measure on the neighbor’s house or get their plans.

12m (39 feet) - 3m (10 feet) means the building area is definitely 9m (30 feet) wide. That is a very good width for a semi-detached house to work with.
Possibly also suitable for an L-shaped ground floor layout.
The plot also has a nice orientation facing west. You can practically look out into the distance from there.

The plot also has a nice orientation toward the west side. You can almost look out into the "open space."The building setback from the western neighbor is just 7m (23 feet). So, it's not that far.
The garage should also be placed there, at least according to the development plan. Although the neighbor to the east did not follow that either.

I’m not really sure why the building zone would have such an odd dimension. But in my opinion, there is usually an obligation to build in the same geometry as the neighbors. So you just need to measure their house or look at their plans.That might actually be quite accurate. The lot area is 263 m² (2,831 ft²). The 12 m (39 feet) width is certainly correct, so the lot is probably roughly 12 by 22 m (39 by 72 feet). The maximum building zone is likely 9 m (30 feet) wide and about 10 m (33 feet) long.H
