Hello everyone,

After reading a lot here and planning for three months now, I’m trying to get some help.
The plot is complicated, maybe a bit narrow to also fit a separate apartment on the ground floor.

We are unsure how to “split” the plot.
Who should get the west or east side?
Which street should the house face?
The 5.5 m (18 ft) setback area on the north side suggests itself as the driveway/parking area. Also, no one wants a north-facing garden.
We all want sunlight somehow, but with further construction progress on other houses (marked in red) and the low sun angle, hardly any sun reaches the southern area.
The separate apartment really only needs a sunny terrace (because mowing the lawn will get harder with age).

I’ve simply added the architect’s two drafts here.

Without an upper floor, it’s hard to say much here. If it turns out to be the same size, the budget will not be sufficient. The ground floor is already about 130m² (1400 sq ft).

Somehow, the architect seems more interested in the granny flat. The ground floor of the main house is being somewhat neglected.

I am also curious to see how 8 rooms will be arranged on the upper floor.

Here is how I imagine it.

I have rotated the plan so that north is at the top.

I wanted to show how this fits into the neighborhood.

These appear to be works from two architects, and I suspect both are "architects" (each essentially draftsmen for prefabricated house suppliers). Single-story ground floors are nonsense, especially when they are placed in front of the upper floors.
