Development of existing plot in BW - primary topic distances, access road

Hello dear house-building experts,

I need your help, or rather advice / opinion.

Current situation:
- The below-mentioned plot is available
- The "old building" is as drawn
- I imagine the "extension" and "new building"
- Blue dotted line is the boundary distance of 2.50m
- Blue dashed line is 3m as access to the new building
- New building and extension are each only one story (although I might possibly have to go up to 2 floors here)
- Old building is 2.5 stories
- Town center in a village with 4,000 inhabitants
- No development plan for this plot
- Parking spaces are 5x2.30m



My concerns are (despite almost studying the state building code):
- Will I comply with these boundary distances?
- Is the access to the new building okay like this?
- Is the extension conceivable like this or are there any regulations that might still apply?

I would be very happy to receive feedback.

Best regards
Rüdiger

§34 practically means possibly "factual building windows" through the street distances of the existing surrounding buildings. The boundary distance is typically only the nominal "common belief" 3.0 (or in BaWü 2.5) meters if 1/2 h is not above it. There may be regulations in the state building code or local law regarding the passage width to the rear building, which are essentially related to the accessibility for fire trucks. The question part "factual building windows" cannot be answered without considering the surrounding properties.

If the front house has no roof overhang and rain gutter/downpipe, then the usable driveway is smaller
