Floor plan of a semi-detached house 7x16m on 390sqm in a settlement

this plan is longer but narrower. Try something like this

draw the 2m line on the upper floor

On the internet there are some floor plans e.g.
Laux Slim
Town & Country Aura 125 slightly shorter

Almost all floor plans on the web are shorter and still don’t look like Tetris.

How large is the distance house to street?

I would place dining, cooking to the east and the living area to the west
Stairs, utility room, cloakroom, WC in the middle
I would try a straight staircase, then upstairs there is still enough space to plan a room opposite the stairs and a long hallway isn’t needed anyway.

390 sqm # floor area ratio 0.4 # floor space index 0.4 # I !!! # SD38 never ever results in what the OP has drawn here. It rather resembles the approximately one hundred and forty SD38 two-storey (II+D) row/semi-detached houses of the classic land developer BT.

390 sqm # floor area ratio 0.4 # plot ratio 0.4 # I !!! # SD38 never ever results in what the OP has drawn here. That actually resembles more the approximately one hundred and forty SD38 two-storey (II+D) row/semi-detached houses of the classic property developer-BT.

But it is :) maybe it's misleading because I didn't draw the 2 m line… but I specially moved the furniture forward so you can see how they will be positioned

Completely regardless of the 2 m line, you have drawn at least one whole floor too many!

390 sqm # floor area ratio 0.4 # floor space index 0.4 # I !!! # SD38 never ever results in what the OP has drawn here. Because that rather resembles the approximately one hundred and forty SD38 two-story (II+D) row/double houses of the classic property developer BT.

that's why the later attic expansion, when no one is watching.
