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

Yes, I’m using a smartphone to access this, and I’m truly a complete beginner when it comes to this type of forum.

Here is the complete development plan! 0.2 or 0.15?

Still 0.2... but you should be able to read that yourself, it is almost clear enough 😉

Sorry – I assumed it referred to the 0.15 on the right side – that’s what everyone involved has told me so far.

I would also guess 0.2, but these dotted lines are confusing. Let's ask @Escroda. Can you read the floor area ratio for us?

Oh sh***
... Use also refers to the floor area ratio...

Sorry, I would have expected a logical street sequence with the individual plots, but like this…
