Floor plan house with granny flat - improvement suggestions?

And, it is just the case that the staircase with the landing per floor costs around 4 to 5 sqm.

Would it not be conceivable to accommodate the brother from your apartment and completely save the 2nd staircase? Then the common room in the granny flat could be expanded by this entire hallway part.

... thanks for illustrating

I’m throwing in another idea, where there is only 1 staircase for 2 residential units on the upper floor. The brother’s room and bathroom could be used by the family or guests when the brother isn’t there. But since the brother also needs to eat somewhere, he probably always sits at the parents’ table, so the 70 cm table and the 200 cm kitchen unit definitely won’t work. There would be significantly more space in the granny flat here: [ATTACH alt="grundriss-haus-mit-elw-verbesserungsvorschlaege-594201-1.png"]74618[/ATTACH][ATTACH alt="1662549485650.png"]74616[/ATTACH]

Thanks "Würfel" for this drawing. It is very clear to see that when the staircase in the granny flat is removed, there is significantly more room in the living room (which some here have already mentioned several times). Unfortunately, it’s not an option for us that my brother lives with us when he is here. Our apartment is already quite full with 3 children and 2 adults, and having one more person in the house would increase the stress factor even more. However, my parents want the brother to live with them.

Speaking of my parents; they have been involved in the planning from the very beginning. Yes, it is true that they would have liked a somewhat larger living room, about 24m2, but they were satisfied with the final plan. We all would have preferred a bigger house, but unfortunately, the budget doesn’t allow for that. Family cohesion, as it is right now, is very important to my parents.

To summarize: everyone wants to live, cook, and eat downstairs, the levels / living units should be separable later, the granny flat needs at least 3 rooms, the other family needs at least 4 bedrooms, there must be at least 2 parking spaces with 5m distance to the street, the utility room must be accessible from the street on the ground floor. The terraces also have to find space somewhere and please draw them into your plan with 3m distance to the boundary each! (This is simply ignored and left uncommented.) And all this on this badly cut mini-plot.

My sincere advice to you: sell the plot and look for one that offers the possibilities you want.

Thanks Katja, that is very well summarized. Because it has already been asked a few times here how old the seniors are – well, my mother is 68 and my father 72. Both are healthy and active, so they want a small piece of the garden to be able to plant something there and thus have a little occupation. We will separate the garden for them.

Unfortunately, that is no longer an option because we simply will not get another plot anymore.

You are evading. That does not answer the question that has been asked here countless times and just as often ignored by you: What do your parents say about this floor plan, about having to "live" on 20m2 for the next 20 years? Can they imagine what an "all-purpose room" consisting of kitchen and living room with 20m2 means and do they know that they will have to eat at the TV table?

We are putting an external spiral staircase on the balcony (-> google). :) And I rotated the whole thing again – the orientation of the terrace on the ground floor was wrong: [ATTACH alt="2-family house-GF.jpg"]74606[/ATTACH] [ATTACH alt="2-family house-1F.jpg"]74607[/ATTACH]

I quite like this plan – especially because the house is quite compact and you also get a bit of garden as a result. The idea with the staircase that leads directly from the living room into the garden is also good. It’s also good that there is only one entrance to the house, which saves space and we also have a shorter route from the garage into the house. What I am missing, however, is a small storage room on the upper floor. Could you please provide the dimensions of the individual rooms? BTW; are you an architect?

Unfortunately, it is not an option for us that my brother lives with us when he is here.

He does not live with you. He goes up the stairs, which are located outside your living area, into the small hallway and then immediately turns into his "granny flat." Your area upstairs would also be separated from your brother’s by a door. You were willing to share the entrance area downstairs with your parents and your brother, right? So you would only be sharing it with your brother? But if you are already prepared to live only on the upper floor, then that is okay. Although I think it gets very cramped for 5 people. The parents would have plenty of space for that :D

That is certainly a clever solution - I had not noticed it that way at all. I will discuss it with my husband this evening. Unfortunately, as always, there are a few disadvantages with this plan; 1. We lack a utility room upstairs and the brother’s shower bathroom is interior (without a window).
