ᐅ Multi-generational house with an underground garage for three families

@11ant

I have thought about it, yes. There is no definitive assessment on this yet.

May I ask you a question? What scope of work would you currently assign to an architect in this case?

Best regards

Let's be honest. You submit a rough preliminary building inquiry just to get an idea of what’s possible before aiming for the stars.

We allow ourselves to pose this question to him.

The brief is clear and consists of two parts:
Desire)
Three couples (two of them in childbearing age, if I understood correctly) want to live there; each housing unit should also be suitable for external users afterwards; it should not look like an apartment building.
Reality)
Does this fit on the plot, even though it is not supposed to be social housing in terms of floor area?

Even in remote areas like Posemuckel / MV, they have such assessments, and they should be requested. In zoning area 34, such restrictions as I have marked are not uncommon: that a setback line requirement in a local development plan creates a building line (in red), and that the surrounding building depths set the limits for the house depth. The otherwise much-appreciated design by Kerstin simply uses a building depth two and a half times that of the neighboring buildings shown in the plan excerpt. This may be possible—but it would not be unusual if it were not.

Densification—and this is what you are aiming for, if you compare the desired building volume with our grandmother’s small houses on the neighboring plots—is currently a trend, welcomed (but usually considered something requiring regulation, often due to poor early experiences with investors by local residents). In larger cities, it is typically local ordinances from individual district offices that define these frameworks.

Hello again @11ant and @ypg.

Thank you very much for your suggestions and explanations.

I have also been considering a possible "building envelope" and will try to clarify that shortly.

Submitting a preliminary building inquiry definitely makes sense soon. However, I believe that as long as the current building regulations, including the permitted floor area ratio and site coverage ratio, are followed, everything should be fine in the initial phase. Our area is purely residential, with a floor area ratio of 1.2 and a site coverage ratio of 0.4.

Best regards

Floor area ratio 0.4... did you mention that initially?

Hello ypg,

No, I didn’t address the numbers at the beginning (which was obviously not ideal on my part), as my initial post was mainly about sharing thoughts with only a few facts included.
