Bungalow with granny flat on land in BY

I don't find the entrance situation bad compared to the elephant,

I didn't say "bad" - I merely see a downside in this configuration of the endosub-entry if the property ever changes owners and the tenant is then not a family member. Then an alternative tenant entrance is missing.

I am happy to catch up on the questionnaire:

We do not want to give up: one level for the granny flat and main part (living, dining, sleeping) of the main apartment; one entrance; double garage; covered entrance; bright dining area;

But really no more info comes across now, does it?

Idea for the roof is a shed roof over the northern and southern u-shaped wings and the rest flat; alternatively all flat.

Site plan?
Budget?

Approximate hand sketch of the site plan is sufficient - it does not have to be a finished execution plan now.

You wrote something about OG. How do you get upstairs and what is there?

Who is supposed to be accommodated in the [Einliegerwohnung]?

Who is supposed to be accommodated in the granny flat?

One of our daughters has a handicap and we would like to build a single-storey granny flat for her (no wheelchair).
