Floor plan, building with tree, granny flat, and existing buildings

So, everything always takes a bit longer than you plan, but I have incorporated many of ’s ideas - so far, I have only managed the ground floor. Above all, I am still a bit smaller (13m x 8.5m), which you certainly notice, as there are still some tight spots here and there. But this whole thing is initially just a draft for us, to better weigh wishes and needs. Since I cannot go beyond a knee wall height of 1.3m with the roof pitch (unless you try to obtain exceptions from the development plan), the attic remains very tight; however, I think the upper floor works as it is. Maybe it will turn out as said and we will forgo the attic and instead have one more room on the upper floor, but I will think about that further tomorrow.

I have now also sketched the upper and attic floors - with the staircase position there is logically no height problem in the upper floor and in the attic there would be two cozy rooms, but you would definitely need a roof window above the staircase. I have also exported a section and a 3D view - since I am not allowed to draw slanted walls in the roof area (wrong module in the program), a few things stick out of the roof surface, please ignore that ;)

The furnishing is still quite generous, we probably won't need that many cabinets on the upper floor and above all, I haven't dealt with the bathroom in detail yet.

Despite everything - concerns, comments, suggestions? After Easter, we would then go to a few house construction companies (with the text form of these drawings)...

I'm getting in touch again, a lot has happened. The soil survey with a lot of peat and a very high groundwater level makes the basement unpleasantly expensive, we have received two estimates of over 200k for it and that would only be the basement in shell construction. Therefore, we are foregoing the basement and have included the utility room in the ground floor room program and the attic will rather be used as storage than as an office. We have now received a draft for this, which I would like to put up for discussion here - we like the basic room layout, but it would be good to make the ground floor a little "smaller" to have a bit more distance from the beech tree in the southeast - otherwise, what has caught our attention so far (no claim to completeness):
- Swap guest WC and wardrobe in the main apartment, change the hinge of the door to the main corridor
- Move the wall between the granny flat bathroom and utility kitchen eastwards to get a bit more space around the dining table
- Omit the north window in the utility room
- Omit the partition wall between "sleeping" and "living" in the HLW and rather achieve a flexible room separation as needed with a shelf/cabinet
Otherwise, I think we are not dissatisfied, but it is the first draft and we have not yet built a house... Therefore, I am still hoping for a few good ideas and advice here, all further information is still in the first post.
I would like to thank you very much in advance!

Possibly arrange the bathroom like this:



Then the wall in the east can possibly be moved 50 cm.

we have received two estimates over 200k for that and that would only be the basement in shell construction.

Oh! :eek:

we like the basic room layout,

It is also roughly what you drew in #17, only the staircase has now been given a better position.

but it is of course the first draft and we haven’t built a house yet...

Has the architect now considered all the possibilities that Hamburg’s building regulations offer? Especially since the room layout is already very similar, I have the feeling that he more or less copied it.
Regarding the problem of the bedroom and the lack of space for a wardrobe, if no spontaneous better idea arises for the staircase or the basic design (it basically takes away your wardrobe space in the bedroom due to the door position), I would see the wardrobe placed under the slanted roof in a DIY or carpenter design, meaning the 90cm towards the front fitted with sliding doors and then pushing the bed closer to the door.
My second look personally told me “quite tight down there,” referring to the living area and not the old gentleman’s bedroom.
You wrote that you are still living together on 61 sqm… therefore the 36 sqm will feel like a palace to you.
However, I would possibly build so that later, if dad goes into care or experiences his second youth again (how old is dad?), the living area can be opened to the granny flat. In this respect, I would take the bathroom out of the middle of the house, also swap kitchen and pantry of the main apartment with the living room so that the living room can be expanded later. Maybe I can make a drawing later (granny flat bathroom by the utility room, wardrobe in front towards the hallway, WC becomes pantry, etc. (I’m writing this without having the drafts in front of me), but I can imagine more satisfying options for later than if you block a lot with technical installations in the middle of the house.
Personally, I think it’s better if the kitchen is located by the terrace anyway.
Otherwise, I think it’s good if you make the most of the roof slope.
It is hard to say more now since the room dimensions can’t be grasped very well.

My second look personally told me "pretty tight down there," by which I meant the all-purpose room and not the old gentleman's bedroom. You wrote that you are now living together on 61 sqm... therefore the 36 sqm will seem like a palace to you. But I would possibly build it so that later, when Dad goes into care or experiences his second spring again (how old is Dad, by the way?), the living area can be opened up to the granny flat.

The narrow tight all-purpose room immediately jumped out at me as well and would be the deal-breaker for the design. Also, you always have to go through the kitchen to get to the living room. Not nice. Sorry, but waiting for Dad to go to a home would not be an option for me. In my opinion, the extra hallway in the granny flat is too much wasted space. Altogether, that is 20 sqm of hallway on the ground floor—already quite a lot. The central staircase position prevents depth and openness from coming into the living room. You would ideally want to open the hallway, but that conflicts with the cloakroom and WC. You are paying a huge amount of money for this narrow tube-like living room—think about that carefully! Swiveling TV—that’s like in a hotel—creepy. I would critically question the idea of accessing the floor with a simultaneous setback in the upper floor. Does that have a deeper meaning in terms of single-story living, or was it just accidentally drawn somewhere? Who is supposed to constantly sweep the leaves off the setback? Or is there going to be a green roof on it anyway? Becoming even smaller on the ground floor is an absurd wish. Now the utility room (HAR) has also been placed down there. How is that supposed to work? Maybe it is better to forego the roof peak and instead completely cover the ground floor with a cheaper staircase location. By the way, what are the external dimensions now? 13x9?
