Sorry, the planning of this house is in my humble opinion quite thoughtless, confused, and rushed. One problem is not even solved, and you are already rushing into the next one, having forgotten the first again. I would call this completely unplanned and see a lot of money wasted here, which you will regret later – but then it won’t be possible to change it anymore. Or did something happen in between that I missed? If so, I apologize.
Could you please check based on the data whether the staircase is okay like this? The opening on the upper floor is 3.5m by 1m.
So what about the staircase now? You have a story height of almost 3m. A staircase with a length of 3.50m is certainly not enough or it will turn into a mountaineering staircase. What exactly are the architect’s specifications for the staircase (number of steps, tread, riser height)?
Another question regarding the entrance area: I would like to replace the masonry staircase wall with a glass wall simply to have more of a sense of space. Has anyone installed something like this and can report how it is? How do I solve the problem with the hallway door?
Your sense of space will get even worse if you now plan to enlarge the hall. Ultimately, you have now put two tube-shaped rooms together at a corner. That’s how you get a living room depth of less than 4m and that for 43 sqm just for the living area! This is totally unacceptable in my humble opinion and just poorly planned.
The only solution is a new approach. Is the straight staircase really so existential?
At present, you have almost 60(!) sqm for kitchen and living. Your architect was already embarrassed by the large amount of unused space and out of desperation drew a pantry right in the middle of the dining room in front of the terrace. I find that absurd. You also wanted to omit it. So have you canceled it now or not?
The granny flat is a catastrophe. Somewhere I read that you were still unsure whether you would actually use it. What about that? Do you really need it? If yes, is that really supposed to be this gloomy kitchenette in the entrance area? Where are you supposed to hang your coat and put your shoes? Maybe on the wall against which you bump when you enter the monster?
I would recommend that you check again what you really get for your money. First, ask about the staircase whether it can even stay like that. If yes, whether it should stay like that with the whole tail that is still attached. Once it is built, there is no going back and the money is gone.
