ᐅ Single-family house with a stepped upper floor – Feedback/Discussion/Tips/Ideas

Hello dear forum community,

it seems there are quite a few building novices, construction experts, or those aspiring to become experts here. We currently belong to the last group, aiming to become more experienced. We are a young family with one child so far but plan to have a second child in the near future.

Therefore, we would like to present our design to you, hoping it can be thoroughly reviewed.

First: This drawing is the initial draft, which we can still change and for which we already have some ideas for adjustments.

Regarding this:
1) The children’s room on the ground floor is intended to become the master bedroom.
2) The master bedroom will accordingly become the children’s room.
3) The shower should be moved upstairs, the bathtub downstairs, making the bathroom slightly larger, with a window, located along the right side of the house extending to the lower exterior wall.
4) The utility room should be roughly halved, remaining in the center, possibly integrating the small storage room.

These are our ideas so far. What do you think?
