Hello everyone,
We are planning to build a house with a separate apartment for parents.
The main house will have two full stories and a hip roof, and to reduce costs a bit, the separate apartment and the garage will have flat roofs.
The house will be built in a new development, and I have already designed the floor plan.
The plot measures 924 m² (11,470 sq ft) and is numbered 30 on the site plan.
Site coverage ratio: 0.4
Floor area ratio: 0.6
Building height: 4.5 - 6.5 meters (15 - 21 feet)
The driveway can only be on the west side because there will be a bus stop on the south side.
What concerns me:
On the upper floor, the east wall runs right above the living and dining area and is actually only supported by the wall between the stairwell and the storage room of the separate apartment. Could this cause any structural issues?
I have drawn the exterior walls as 45 cm (18 inches) thick and the interior walls as 15 cm (6 inches). Load-bearing walls could probably be reduced to 20-22 cm (8-9 inches).
The “wet rooms” like bathrooms and toilets are spread throughout the house, and the separate apartment will have its own heating system. The sewer drainage gullies are located at the south edge of the plot near the bus stop.

Could you share your thoughts on this design?
....
What we are considering is whether the kitchen and living room in the single-family house should be open to each other, so without a dividing wall...
Ground floor: 
Upper floor:
Paving:
I am somewhat speechless. How can anyone let these things stand and be discussed when it’s obvious from the beginning that they won’t work?
There are quite a few elements that interfere with each other… for example, one person ends up with a door right behind their seat, and another door can only be opened to about one third of its width.
Regarding the secondary apartment with barely 17 sqm (183 sq ft) for the entire living space, there is no point discussing it. As for the 40 cm (16 inch) clearance around the bed frame, you can’t get up without hitting your head.
Oh yes, I forgot your quote about the open kitchen: you should definitely know that before planning. Some people like it, others don’t. But you should be aware of or at least have a sense of your preference.
P.S. Just paving the driveway will cost at least 15,000 for labor alone... is that really what you want?
Regards, Yvonne

Should the granny flat still be designed for the same target group as before? Ypg, Yvonne has already made relevant comments regarding the open-plan area and bedroom, so I’ll add points about the bathroom and the headboard placement below the window... You probably wouldn’t want to sleep with the window open there, or you might wake up with a stiff neck from a draft.
Honestly, I’m a bit shocked that space is being saved in essential living areas, yet nearly 19 m² (205 sq ft) is allocated to accommodate about 7 m (23 ft) of shelving with a depth of 40 to 50 cm (16 to 20 inches) and around 3 m (10 ft) of shelving with a maximum depth of 30 cm (12 inches), plus a freezer cabinet, all to make the hallway to the sauna look “stylish.” The sauna itself is 150 x 150 cm (59 x 59 inches)... well.
And then the entrance hall is 12 m² (129 sq ft) just to fit a 150 cm (5 ft) wardrobe.
Symmetry of the main entrance seems to override everything.
To get from the kitchen to the terrace... it’s either through two doors or a zigzag route past the dining table and sofa.
The utility room... in my opinion, this just won’t work. Who’s supposed to replace the heating system or carry out maintenance in there?
The staircase will be extremely tight for moving furniture upstairs.
What is supposed to happen upstairs with the ground floor of the extension?
PS: When will an architect be involved in the planning?
And the granny flat isn’t for people who want a more spacious, brighter, or similar living environment. Terrace space for that?

Some time has passed, [...] Could you say something about this design? Yes, I don’t see that time has been well used. Maybe it’s due to your professional mindset? This house still feels like a complex puzzle designed by a mechanical engineer: the rooms interlock like gears, and the gaps between them are just wide enough for lubrication. The scale of the building world, with its tolerances of several centimeters, doesn’t seem to have become more familiar to you through your previous attempts. The main building volume has at least become clearer, but you have kept the design principle of adhering to minimum clearances — consistently, right up to the point where the next room box can fit. It’s almost to the point where new furniture would have to be ordered in the exact dimensions of the old pieces. Furniture is called that because it is movable — but being so “built in” around minimum clearances makes it very difficult to change their positions relative to each other; basically, all pieces could be fixed in place (or chairs at the table only linearly movable). Explaining this to a planner like that (basically a clumsy traditionalist) won’t be an easy task for either party.My feeling is that at some point we had made more progress.

So, there is a new plan and we have designed the granny flat as an extension. What we don’t know yet are the exact window widths, so the widths are not 100% finalized.
In child’s bedroom 2, the corner behind the stairs is a bit awkward. Do you have any suggestions for that?
The yellow area is the courtyard, and we have considered planning it with two driveways so that you can drive a small circle in the courtyard. It is 5.5 meters (18 feet) from the garage door – is that enough?
In the living room, there is again a projection that is used as a balcony above.
The heating is located on the upper floor in the laundry room, so only one chimney is needed for the fireplace and the heating system.
Child’s bedroom 3 is planned to have kitchen connections as well, so that a kitchen could potentially be installed upstairs later, and the wall between child’s bedroom 3 and the master bedroom could be removed to create an open living/dining area on the upper floor. Would this idea work well?
Is this plan fundamentally practical or is it a disaster again?

What we don’t yet know exactly are the precise window widths, so the widths are not 100% finalized. For brick, sand-lime brick, etc., multiples of one-eighth of a meter are usually used. For aerated concrete, multiples of 5 cm (2 inches) are still practical. I wouldn’t recommend using unusual or non-standard dimensions. Common sizes for interior doors are 88.5 cm (35 inches) for rooms, 76 cm (30 inches) for small bathrooms, or 63.5 cm (25 inches) for guest WCs or storage rooms; for apartment doors 101 cm (40 inches), and front doors often 113.5 cm (45 inches). Single-leaf windows usually come in 101 cm (40 inches), 113.5 cm (45 inches), or 126 cm (50 inches); double-leaf windows start at 151 cm (60 inches); toilet windows are 76 cm (30 inches).

It’s 5.5 meters (18 feet) to the garage door—is that enough? That will comply with building regulations and the development plan; with a sectional door, it will also work well practically.

Would this be a good idea? Where would you place the division on the ground floor so that a separate apartment could be created upstairs?

Is this plan fundamentally workable or another disaster? Both. Maybe a bit less of a disaster than before. What remains is, in my view, your unfortunate approach. Somehow, it seems like you are working with a very limited field of view. And for your fixation on a perfectly symmetrical front elevation, harmonious proportions are compromised in many places. Aesthetically, that could prevent exactly what you are trying to achieve(?)
The minimum furniture dimensions arrangement seems to be slowly loosening up a bit, but there is still a long way to go overall.
