I do see a certain timing issue, since after 1 year interest on the provision will be charged. Construction time from the floor slab is 6-7 months. But you are right, we are probably thinking more conservatively or conventionally...
But much is already wrapped up and we are reluctant to bring in another architect now (which would cost more money again). I have also already discussed an open living concept with my wife and we have already experimented a bit with the floor plan. But we always end up with a rather classic orientation.
regarding the 2nd post:
The kitchen is probably only a draft from the BU. Our idea is actually rather different. We roughly sketched it in our floor plan sketch in the initial post to show what we imagine.
Regarding the access to the bedroom through the dressing room, that would be a good alternative. We will have that drawn. Thanks!
Regarding the bathroom on the ground floor, the layout is also from the BU. How can a shower door best be integrated there? It almost only works with a standard sliding shower partition, right? A glass door would be much nicer! Or a glass folding door?!
