Buy or leave?

Hello!

A new residential area is being developed near us, and I want to buy a plot of land there to build a semi-detached house. Each half should have about 150m2 of living space, plus 2 garages and 2 parking spaces. The plot has a size of 750m2, floor area ratio 0.4, floor space index 0.8, ridge height 4.5m, eave height 9.5m.

I went for consultation to the local building authority and they said I should be careful with the floor area ratio of 0.4 and my plans, but they did not go into details. The semi-detached house should have a footprint of about 15x15m; where the garages will be built I cannot say yet, nor the paths to the garages. I would build them to the right next to the turning area but that would lack the required distance to the street and would only be permitted in special cases.

Assuming that a long driveway to the garages has to be built and the floor area ratio is thereby exceeded, would that be acceptable? I read that exceedances of up to 50% for ancillary facilities (driveways etc.) are tolerated (NRW).

What do you think about this?

can't say anything about that

According to the draft, I see that no semi-detached house is planned there, or am I seeing that wrong? Otherwise, better spend a few marks more and build a regular single-family house! I unfortunately cannot say to what extent the floor area ratio is tolerated. Otherwise, if there are still plots available, I would prefer some others, especially in that regard!

(4) In determining the base area, the base areas of
1.
garages and parking spaces with their access roads,
2.
ancillary facilities within the meaning of § 14,
3.
structures below the surface of the terrain, through which the building plot is merely underbuilt,
are to be included. The permissible base area may be exceeded by the base areas of the installations referred to in sentence 1 by up to 50 percent, but not more than a base area ratio of 0.8; further minor exceedances may be permitted. The development plan may contain provisions deviating from sentence 2. Unless the development plan specifies otherwise, in individual cases, compliance with the limits resulting from sentence 2 may be waived.

This is stated in the Baunutzungsverordnung. However, you must do the calculations yourself, as that depends on your planning.

P.S. Driveway to the garage on the right and left of the house takes up a lot of space!

Unfortunately, the link with the development plan was deleted by Admin, and uploading the development plan as an image file is impossible because it would need to be enlarged perhaps tenfold to be able to read the tiny texts.
