Floor plan of a single-family house approx. 170 m² on a narrow 750 m² plot

Then we still can't get behind the house if the garage is at the back of the house :). I think it will also be too tight to drive in.

There are also garages you can drive through. Maybe that is an alternative?

What motivated you to choose this layout?

In general, the orientation of the rooms fits. Ground floor: Large contiguous living/dining area, pantry well accommodated, storage possibility in the hallway (wardrobe behind the front door), guest WC with shower (for old age), possibility to easily create an additional room (in the living room, for old age), relatively large utility room possible (no basement) Upper floor: Office possible (with dormer), dressing room for parents possible, room sizes are okay (still need to be calculated with the roof)

Room sizes are fine (still need to be calculated with the roof)

Because you haven't yet determined how the increase of the house depth by half a meter affects the 1m and 2m lines?

Correct, and because the sample plan is designed with a hip roof, similar to a city villa. We want a gable roof, and we still need to look for the appropriate knee wall height.

Wow, that makes the sample floor plan largely unsuitable. How much knee wall height do you think you would have?

You are flexible then. max. H: 10 m
