ᐅ According to the floor area ratio, only 138 m² are allowed for a two-story building – need help :)

Hello, I have the opportunity to purchase a plot of land in the Hannover region with an old Okal prefabricated house. We would remove the existing house and potentially use the existing basement (which is dry). Now the challenge – the development plan specifies the following: II, floor area ratio 0.15 in the WR zone – the plot is 926 m2 (9,965 sq ft) and faces west – which results in 139 m2 (1,495 sq ft) – is that correct?

We are a young modern family of three and can imagine living in a small house. However, I currently have no idea how much net living space would remain, nor how the house could be designed.

Can I get some ideas here? Are there similar cases? I am attaching the current basement plan.

What we like:
cubist architectural styles
covered terraces
open living concepts

So it is 0.15 after all – I didn’t misread it

We’re still waiting to hear what our leader has to say, who doesn’t seem to be online right now.

...

Once again, the plot ratio for the property marked with a red cross is 0.15. The floor area ratio is not defined.

To put it differently, the floor area ratio, or FAR, for the property marked with a red cross is 0.15. The plot ratio is not specified.
Who says that? The plan clearly indicates the floor area ratio. In my opinion, there is no room for interpretation based on personal judgment. However, I can imagine that the building authority might be open to some exceptions after more than 50 years. They might just want to avoid the cost of a completely new plan, which would be pointless for the already developed properties.

... an architect I once asked!

I have received the following additional feedback:

I have just done some basic research again. The floor area ratio is set at 0.15, meaning 15%, in the development plan, so you actually only have 138.50 m² (1,492 sq ft) combined on both floors available. Depending on the construction, this corresponds to a net living area of approximately 110 m² (1,184 sq ft) for the house.

Amazing 😉 how much can be interpreted from that...
