Floor plan house with granny flat - improvement suggestions?

I recall a comment that the OP bought the plot on the recommendation of the BU. How can they recommend that under these circumstances, I wonder?

Yes, but I also remember this:

We want to build a city villa with 2 full floors and a garage, but without a basement. The living space should be approx. 180m2 .

we (my husband and our 3 children)

We changed our mind at short notice. It sounds a bit strange, but we ourselves are a bit surprised that we decided on a different plot shortly before the end

we are not particularly decisive.

Yes, I do remember this as well:

I don't remember this now. That must be from the old thread. Presumably, what started as a planned standard townhouse suddenly became a townhouse with a granny flat thanks to the parents, and now with the brother it's a townhouse as a two-family house. The wishes exploded along the way, so to speak. Of course, I can understand if a BU who goes through this journey eventually gets fed up. :D

It's more about functionality and a settled, calmer way of life than about three-course menus and a house for friends.

Well, the parents were something between their mid-60s and early 70s. Now that I’m also over 60, I have to say I don’t want to give up cooking for friends and inviting them over in the next 10 years.

Thanks to everyone for the many comments. Unfortunately, I cannot always respond promptly because my daily routine is a bit disrupted due to shift work. I would just like to briefly say something about our BU and the architect; we did not select the architect ourselves, he was assigned to us by the BU, as the architect has been working with the BU for several years. The architect's fee was also paid by the BU or was already included in our cost calculation. I think we made a mistake here and it would have been better if we had commissioned an architect ourselves and settled his services directly with him. Especially because later in conversations with the architect, it turned out that he mainly plans commercial properties for the BU. Since the architect and the BU are partners, the planning of the architect was not critically questioned by the BU. My husband had already had a bad feeling about the granny flat and had asked the BU before the building application whether the granny flat on the ground floor might be a bit too small and if we should possibly redesign it. The BU then said that the architect's planning is fine for 2 people; the granny flat on the ground floor is definitely not too small. Regarding the plot, I would like to add that we had spoken to the BU before purchasing the plot and the BU had told us that the plot is well-suited for our building project. Please do not misunderstand me now, I do not want to shift the blame to the BU or the architect. However, we do believe that we did not have a lucky hand with the choice of the BU and the architect. But we no longer want to keep worrying and constantly telling ourselves what if, etc. The groundbreaking has not yet taken place and we are optimistic that we can still make the best of our current situation and design the floor plan so that it perfectly suits our needs. Currently, we are not planning a room for my brother in the granny flat and if he visits our parents, he is welcome to stay in our guest room. Würfel has already made a very good suggestion on how the planning could look if the brother has his room with us in the apartment. Maybe Würfel or someone else would like to add something to this plan or make their own suggestion?

I can of course understand if a BU who participates in this trip eventually gets fed up. :D

He’s not fed up at all, he’s just indicating that the pricing can no longer be maintained given the delay.

Well, the parents were something like good mid-60s to early 70s. Now that I’m also over 60, I have to say I don’t want to give up cooking for and inviting friends to eat in the next 10 years.

Neither do I. That’s why I would _not_ have a granny flat built for myself, nor move into one. That is mutually exclusive for me. That’s also why I always ask about the age of the seniors when this granny flat topic comes up. The so-called retirement home of most active seniors nowadays is not inhabited just over 60, but just over 80. My parents, 80 and 78, would never move into less than 85 sqm. They’re quite happy with their current 160, even though my mother can’t do as much anymore. Building new or changing one’s own living space and the consequences must probably be considered, played through, and if necessary postponed for years or have a Plan B ready. For example, it would be possible here that the granny flat is initially occupied by someone else, the parents move into the ground floor of the other two-family house, and then, when the son becomes independent and completely moves out—in several years—they could occupy the granny flat, if the two-line house and the two-room apartment are then enough.

the planning of the architect i. O. for 2 people is definitely not too small for the granny flat on the ground floor.

…when the motorhome is parked in front of the door ;)

Maybe Würfel or someone else would like to add something to this planning or make their own proposal?

Would you then give us the post by so that not everyone has to browse through the pages here? And would you also share your opinion on our efforts, what you find good or bad? That is missing in my opinion in each of our idea developments from you. There is simply no feedback from you so that we know where it is worth working on.
