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.

I do see some differences, possibly some improvements (I also want to be fair), but there are still aspects that could be done better if one would allow themselves to think outside the box.
For example: the kitchen island should be positioned closer to the bottom of the plan, so the path to the dining area is more direct.
The orientation... well, that would be a dealbreaker for me.
You can see the coat rack from the sofa, the staircase is still a budget version, the kitchen table attached to the island looks unplanned, and the separate apartment is far from accessible for people with disabilities and doesn’t even have garden access.]

Somehow, it all feels inconsistent, with many awkward paths and no rooms that invite you to stay. Overall, it just feels cramped, cramped, and cramped.

The labyrinth-like folding of the walls reminds me of cross-sectional drawings of window frames or mitochondria. The house is definitely perfectly wind-resistant, given the complex bracing of the angled walls. The rooms are densely packed, as if designed by a Tetris master. But you simply can’t take a deep breath between these walls.

But the differences are quite minor—the difference between stagnation and going around in circles is barely noticeable to the naked eye.

The highest priority placed on the secondary living unit wing—due to the symmetry dogma that it must be as wide as the garage wing—is, in my view, too high a cost. It just doesn’t feel right if the grandparents of one’s own children are supposed to live there.

Although not in terms of square meters, the sense of space of this secondary apartment is essentially that of a built-in camper. Overall, this house is a display case where furniture is arranged along with its users.

I second that.

Soften some of the corners and edges in the floor plan. It already starts with the garage. With 3 or 4 children, you usually need a van. Exterior mirrors – exterior mirrors wider than 2 meters (6.5 feet) and 5 meters (16.5 feet) in length make the space tight. The doors on both sides should be able to open. Bicycles, ride-on toys, etc. also need room.

The granny flat is not wheelchair accessible. There are plenty of floor plans available as examples. The goal is not to accommodate grandparents as severe care cases at home, but with limited mobility or home care services, it can be very helpful and convenient.

Everything feels cramped. Six people want to put on their shoes and jackets at the same time.

Find an architect.

Kbt’s floor plan is better.

No sauna anymore either ...
It was initially where the heating system is now. We considered relocating it to a garden shed or into a corner of the laundry room upstairs.
kbt09 schrieb:
Stairs .. well, generous is something else.
Yes. There isn’t much space available for them.
kbt09 schrieb:
I don’t see a wardrobe for at least 5 people in the larger area anywhere.

Our wardrobe is in the storage room by the garage; the entrance area is meant only for guests’ belongings.

There is no terrace access from the living rooms of the granny flat either.
There is a door leading outside from the storage room.
kbt09 schrieb:
Technical room all the way in the south and nothing else planned for the entire complex. What about the electrical distribution in the granny flat? And the heating shares the room with a toilet… what is that for?

The heating still hasn’t found a permanent spot. We also thought about putting it upstairs in the laundry room, or reducing the size of the playroom downstairs and creating a room there with an outside door (kind of under the loggia).
kbt09 schrieb:
Garage side room .. do you really need a door directly into the house and another one outside by the front door?
That’s how we have it for now because our wardrobe is there. The main entrance is reserved for “guests” and not for us. We use the side entrance about 80% of the time so the main entrance stays tidier.

I would still prefer my version ..
Yes, I’ve already redrawn that one with some changes. However, something I haven’t mentioned here yet: on the south side facing the street, there are very tall trees that let sunlight into the garden when the sun is high, otherwise the garden is quite shaded.

That sounds harsh, I know, but you asked for thoughts. To keep it brief: The kitchen at the top of the plan. 181.5cm wide.
I took the dimensions from a kitchen currently in one of our rental units. There, the corner has a stove at a 45-degree angle and next to it is a 60cm (24 inch) countertop. That totals 160cm (63 inches) wide, so 181cm (72 inches) would fit fine.

I also don’t get the connecting room

Consider it as a room belonging to the granny flat or, as mentioned before, a room that both parties can use.

The kitchen island should rather be positioned at the bottom of the plan,

But that is where the fitted kitchen is?!

Yes, I sketched that corner in the hallway just before posting; it used to be a straight wall before.

I agree with that.

This is about the roof shape; it’s a hipped roof on the house, the granny flat, and the garage.
haydee schrieb:
Remove some corners and edges from the floor plan. It already starts in the garage.
Yes, that’s something to consider or improve in the planning phase.

The storage room is 22 sqm (237 sq ft), that should be sufficient.

I have already looked at about 50 shell constructions and have seen much worse floor plans where I shook my head, even though apparently I know little according to you all.

Of course, this plan is not 100% perfect, but some things we really want are included. Although fewer than in the very beginning of the planning. If we let go of one or two wishes, we could plan it completely differently.

The previously mentioned plan also appeals to me a lot, but there are some points we don’t like:
- Long, narrow corridor to the living room
- Direct access from the kitchen to the storage room must be possible
- No side entrance at the front
- Kitchen, dining, and living areas should be arranged around a corner
- Bathroom arranged around a corner upstairs is not to our taste

I didn’t know the storage room is also supposed to be a cloakroom. That is usually located near the front door. This also means that the area between the kitchen unit and the work island remains a passageway.

You should take your space requirements and your plot to an architect.

Just because you don’t like other floor plans doesn’t mean yours is good. Your layout somehow fits a lot of space in. I wouldn’t want to live like that with six people.

You shouldn’t make the space for a staircase too tight – when moving between floors, you certainly don’t want to feel like you’re in a pneumatic tube (?)

Next time, please warn me before you cause such a laughing fit with shortness of breath. This is the ultimate comedy highlight: the main entrance is placed right in the absolute center anyone has ever seen – and normally you’re supposed to go through the servant’s entrance *ROTFL*
