Floor plan design of a two-family house, city villa with a hipped roof

Good evening,
I had already posted my draft once. At that time, it was not quite finished yet.
Basically, I really like the room layout. What I don't like is the hallway. Maybe you have an idea how to design it better.
In the end, I thought a lot but did not come to a better result than this.
The floor-to-ceiling window in the bedroom will be replaced by a normal window. The balcony will be built with 3 round supports.

I had already posted my draft. At that time it was not quite finished yet.

That was this project: - and now it already looks significantly downsized. However, back then

A road runs around the property. Thus, parking space 1 is directly accessible from the road. The other parking spaces are accessible via a wide driveway. It is also marked on the plan.

there was an existing building to be seen. Has its further use been reconsidered since then?

Originally, I wanted to build this 4-family house, but that would be too big for the "small" plot and I would have needed 8 parking spaces. Since I didn't want to ruin the plot like that, I have now decided on the smaller version. The existing building will be demolished soon.

Here is also a 3D model from the south side

In my opinion, you have about 100m2 per residential unit. Why don't you divide the property and build a semi-detached house? Then place one house a bit deeper to stay more on the property. If I remember correctly, you want to live in the house yourself. Do you prefer upstairs or downstairs?

The existing building will be demolished soon.

What is the reason for this?
