Floor plan bungalow approx. 160m² living area

You don’t get morning sun at southwest.

What kind of green strip is that?
Wouldn’t it be better to mirror the floor plan? Garage next to the neighbor.

Garage wider. At least on one side the doors should open and getting in and out without a shoehorn should be possible.

Your budget and the personal contribution are ambitious.

Why do you want such a strong separation between parents and child?

So, now I finally get to answer...
Of course, I had a slip of the pen, the bedroom has windows facing south-southwest and south-southeast.
I have now attached the north-oriented site plan as well as a north-oriented version of the design and a section of the development plan.

The green strip is public and will be planted with shrubs/trees.

I had planned the garage on the side facing the green strip for two different reasons. On the one hand, a 5 m clearance to the public traffic area must be planned in front of the garage, which is why it makes more sense on this side due to the pointed shape of the plot. Otherwise, you would have to move the garage to the back and would not have a uniform house frontage. On the other hand, it is planned there to make sure it stands free and no neighbor’s garage is built directly against it. We have already had negative experiences here (improper sealing of the neighbor’s garage, water in the separating wall which caused paint/plaster to flake off, etc., and simply created a negative atmosphere with the neighbors).

The separation between parents and child occurred to both me and my partner. Although it certainly won’t be a problem in the early years, once you have teenagers making noise or playing loud music, this separation is not a bad idea.

I don’t know why you want to reinvent the wheel of the bungalow. There are good plans that you can easily modify with a few details for your own use. Honestly, I don’t see that here.

We looked for plans but didn’t find any that meet the requirements of 2 children’s rooms, 1 office, and 2 bathrooms :-(

Isn’t that green area on the plan in the north?
Isn’t the property accessed from "An den Eichen"? How do you get to the garage on the north-northeast entrance side?

No, that was because tapatalk rotated the pictures... the green strip is more to the east. The access is of course from "An den Eichen". The garage should have a driveway in front of it which will be covered with a carport.

So the question would be about the reference level for these height indications

The following is stated in the textual regulations:
Height of the structures
Main building
The top edge of the finished floor (OK FB) of the ground floor, measured at the middle of the facade, may not be more than 0.5 m above the reference point.
The maximum building height of the main buildings above OK FB is limited according to the usage template as follows:
• in the WA 4 area a maximum of 5.5 m with a roof pitch of 0-20°

I had concerns about the 20° (I believe standard roof tiles start at a minimum roof pitch of 22°) and wondered whether realizing the floor slab using prestressed concrete elements and insulation wouldn’t be more cost-effective than a complete roof structure with tiles, etc. But I will definitely analyze that in more detail.

I agree with and advise to plan everything anew

I will take your many pieces of advice to heart now, study the heat distribution more closely, and rethink the arrangement/division of rooms.

Eventually, an architect will advise us, so it will certainly turn out quite differently.

I will of course also post further designs here.

Would swap kitchen and sleeping area in terms of orientation. Terrace facing the green strip, shielded from view by the garage.

Possibly move the garage slightly backward. No uniform front anymore. However, entrance from the side
- Corridor is eliminated
- Door to the utility room can be omitted

Parent-child area does not have to be separated so extremely. There is so much noise in the children's room that despite the bathroom and dressing room in between, you can still hear something, so the current separation is useless. What do you do when the children, or young adults, take over the living room?

Regarding the door to the utility room garage
As long as the garage is that narrow, no one will use the door as long as a car is parked inside. You cannot get past with a basket, etc.

On the one hand, a clearance of 5 m to the public traffic area must be planned in front of the garage, [...] The garage should have a driveway in front of it that is covered with a carport.

Sometimes this clearance also applies to the carport, and can therefore not be "used" with one.

Otherwise, the garage would have to be moved to the back and there would be no uniform house front.

In what way is that a value in itself?

The top edge of the finished floor (OK FB) of the ground floor, measured in the middle of the facade, must not be more than 0.5 m above the reference point.

And which one is that: the street level at this point, a specific measuring point in this area, a manhole cover, etc.?

Here I had concerns because of the 20° (I believe the standard roof tiles start at a minimum roof pitch of 22°)

I would probably aim for an exception to 22° rather than deviate to another roofing concept.

As long as the garage is so narrow, no one uses the door while a car is inside.

No car comes in at all due to the lack of a gate; you would have to wall it in.
