City villa floor plan - suggestions for changes?

Widen the extension by 60 cm
Then the bedroom is 4.30 wide
Wall bed 1.4 cm
Bed 220 cm (frame, care bed base)
Bed wall 70 cm

Now the extension should be outside the building window, therefore rotate

Entrance would then be without intermediate construction in the north

Intermediate construction will be technology for both buildings. Can be enlarged in length

Quick question on the side: why gas if a tank is necessary? Why not a heat pump?

For most rooms the sqm specifications are missing but you maybe have 240m² for the whole house?
