Floor plan of a new multi-family house with 3 residential units, living area approx. 350 m²

Your parking space situation is, in my opinion, rubbish. Tool shed in front of the windows? My suggestion. With district heating technology, in my opinion, it is not that necessary.

I agree with you, the location and size of the shed would have to be adjusted. I find your suggestion interesting; if you move the second parking space from the bottom slightly upwards, there would also be a passageway to walk through. The parking spaces on the EAST side would be slightly narrower, 2.5m, but it would fit. If necessary, the front door can also be shifted slightly in position so that 2 parking spaces can be placed to the right of the entrance along the house wall.

but a small hose 150 cm wide could also become tight.

I also prefer parking spaces like this, but devices will probably also include the bicycles, and there should still be some kind of passage to the street, otherwise you probably can't get the bicycles out properly. I also don't quite understand why it has to be this minimal bay window.

Hmm... the thing with the technical room is an annoying matter. If I correctly understand the other contributors, one would have to maintain a width of at least 1.8m, so 30cm more than now.

Thanks for the hint regarding the passage and shed size.

Isn't there an electrical connection with a distribution box, water connection, etc., from which the apartments are then supplied separately?

I tried this version yesterday. Carports are only about 5 meters though, house slightly shifted backwards.
I don't find the floor plan very successful now, but more efficient utilization despite the long corridor, two supply shafts between the storage room and toilet (top left) as well as kitchen and bathroom (bottom of the plan).
Shift everything a bit, move the shed forward... maybe then you come under the floor area ratio limit.

Hello ypg,

thank you for your design. I think placing the utility room in the TRH area is a good idea, but in this case I would add a laundry room there and keep the bicycle shed outside. Then the bathrooms in the apartments can be a bit smaller.
Otherwise, I think it's great that you integrated an office, but I would probably swap K2 and the bedroom so that the parents' bed is on the garden side.

However, you only marked 4 parking spaces, was that intentional? How wide are the parking spaces each?

It is proving difficult not to lose too much space due to the corridor.

Here even simpler: TK in the house including bicycle room... then eventually the floor area ratio will also work out
The carports are each 3.20 x 6.00, one parking space in front of the carport at the TK room. The yellow is a trash bin

That is interesting, if the parking space in front of the carport works out, then I would do the same on the other side as well.
However, I would keep the bicycle room outside (shed) and use the room in the TRH as a laundry room... what do you think about that?

Can you also tell me which program you designed it with?

The parking spaces on the EAST side would be a bit narrower at 2.5m but it would fit.

2.5 m is within the standard, but unfortunately no longer up to date. Perhaps it would help to take up the suggestion from and move the house 1 m to the south.

The technical room of this size is sufficient. It has enough space for a district heating station, a meter cabinet, and the water connection lines.

You don’t want any help at all, do you?
The DIN with the dimensions is written for you and you don’t care.
Well, at least you responded to the post where the technical room is nicely arranged within the ground floor.

Regarding the laundry room: somewhere I also read that washing machine connections are mandatory. And honestly: everyone probably prefers to wash inside their own apartment rather than on the premises where others also wash. However, it would be a good drying option for those who do not own a dryer.

however, you have only marked four parking spaces, was that intentional? How wide are the parking spaces each?

In front of one carport (we very often build carports for small multi-family houses) there is such a parking space as the fifth parking spot.

That’s interesting, if the parking space in front of the carport works, then I would do the same on the other side.

I am now consciously choosing a version where I keep the west side free of parking spaces because you look at the vehicles from the ground floor, and that is not pleasant. On the east side there is still the technical room and mainly utility rooms. In the north, however, it is not so nice and disturbs the ground floor.

2.5 m is within the norm but unfortunately no longer contemporary. Perhaps it helps to take up ’s suggestion and move the house 1 m to the south.

I would still have reservations here if I were you:

"At least 30% of the open spaces of the property must be planted with native, site-appropriate deciduous trees."

Therefore, this does not refer to the total plot area but

Google is not clear on this.
More clear is a design statute of the city of Frankfurt, which takes the climate issue quite seriously.
This might also be the reason for the planting obligation in your case.
The statute says among other things:

§ 1 Objective of the statute
The statute aims to ensure the use, design, and planting of open spaces on properties and the greening of structural installations in a climate-adapted manner in order to guarantee healthy living conditions and to preserve natural foundations of life.

§ 2 Spatial and factual scope of application

[*]
[*][I]
(1) The statute applies throughout the city area to the non-built-up areas of developed properties including the underneath open spaces (property open spaces) and to the external design of structural installations.

[*]

I would follow up once again with the building authority because if the parking spaces are included, then the front yard as it is currently shown is not exactly desired.

So: it may be that although you are allowed to build 3 residential units according to the development plan, it will not be approved just like that. A development plan permits a lot, but another clause can nullify it again.
