Actually divide the property but both have the same building rights

Here is the proposal from the realtor.

Looks reasonable. Is there access from Wester? Because otherwise the left garage would need a massive driveway. Is the plot level? Does the development plan allow for the construction of semi-detached houses?

The blue area is the building window? Then that's barely enough for one house.

Yes, but it still has to be divided.

Looks reasonable. Is access possible from the west? Because otherwise the left garage would require a massive driveway.

Is the plot flat?

Does the development plan allow construction with semi-detached houses?

Thanks for the response.

Yes, access from the west is possible and the development plan allows for a semi-detached house.

The ground is more or less flat.

Duplex house is possible, of course. But everything will be a bit tight. I would refrain from an actual division. It only costs and hardly brings any benefit.

14x11m is enough for a semi-detached house. So 7x11 m for each.

Regarding the floor area ratio, you have to consider that

559 m² => 168 m2 buildable
and 441 m² => 132 m2 buildable

Minus 77 m2 from the building volume leaves still 55 m2 for garage, garden house and access path on the smaller lot. Is that enough?

In my opinion, it should be sufficient

But everything is getting a bit tight.

That depends on the requirements of the OP and their building partner, which we unfortunately do not know.

I would waive a real division.

I would not.

It only costs.

It brings me income.

brings hardly any benefit

It does for me. Whether it benefits the OP depends on their desire for independence. I prefer maximum independence, which is of course already limited in a semi-detached house. Now, depending on the development plan, there are many levels of dependence. One could make a shared access, shared parking spaces, or the mentioned division according to WEG. To better assess, many pieces of information are missing: - from when is the development plan (site coverage ratio, floor space ratio, and ancillary facilities) - what else does it specify (ancillary facilities, heights) - exact terrain heights - what is important to the OP (priority list) Here is a suggestion based on the preferences revealed so far (equality and maximum south garden): [ATTACH alt="Lageplan.png" type="full"]51589[/ATTACH]

but the building partner is not sure whether his building properties will remain unaffected.

Since the site coverage ratio and floor space ratio are relative figures, the possible structural utilization of the plots naturally depends on the plot size. Fairness can therefore only be achieved if not only the building area is divided centrally but also the subplots are equal in area.
