House orientation for new construction on a north-facing plot - ideas, tips?

Hello building experts,

I have already asked some questions in this post, but now I wanted to create a separate post because I believe it no longer fits with the original post.

We are planning a new construction of a single-family house with about 160sqm-180sqm. The house will be about 10x11 / 9x12 meters in size and will have a gable/bay window. On the upper floor there should be three children's rooms, the master bedroom and a bathroom. On the ground floor there is the utility room, living room, kitchen, office and a bathroom with a shower.
A garage or a carport with a storage room is to be built (depending on what the budget allows).

The development plan includes the following restrictions:
Border encounter: 3m to the neighboring property only for garage/carport with a max length of 9m, with corner development 15m border encounter allowed.
House: 4m eaves height, 9m ridge height, no gable orientation prescribed

I have now roughly created and attached floor plans for the west and north orientation.

Pictures 1 and 2 show the new development area and the location of the plot, the pictures are oriented north.
The plot is about 27x27 (see Grundstück_maße.jpg).

The other pictures show the floor plans or the considerations regarding the orientation on the plot.
Unfortunately, I could not find a suitable tool to better represent the orientation. The large black shape should be the house, the small one the carport/garage with storage room. These pictures are not oriented north, but rotated, roughly facing south.

A south orientation is still conceivable, but we wanted to leave space for the well-known nice neighbors to the east and north and actually prefer not to build up the plot there.

If the neighbor sets his house with 9m height directly on the border, there remain about 14m to the west and about 12m (+ the 3m border building) for the west and north orientation respectively.
Is that enough for sunlight in the evening (5:00 pm - 8:00 pm)? Or does sunlight also reach in autumn and winter?

My main problem was that the utility room should not be located in the south and I have no idea where to put the garage or carport at all.

I hope you can help me with this problem.

Sören

Well, then I will rotate .. you can do that wonderfully with the small program IrfanView.

Location variants:
Variant 1

Variant 2

Variant 3


House variants:
Variant 1:


Variant 2:


-------------------------
Especially house variant 2 you should check the knee wall (only 4 m eaves height) and the size of the stairs. Unfortunately, the drawings do not contain any measurements.

Location variant 1 with house variant 2 is close to what I would do: house as close to the north and east as possible, garage all the way to the southeast. Then you still have a nice area in the west. And the neighbor to the west also has to keep distance: He can only put a garage far to the east.

If the neighbor places his house with a height of 9m directly on the boundary

He is not allowed to place his house on the boundary.

Where there is light, there is also shadow. No one ever manages to align everything perfectly with the sun 100%.

In autumn, the sun sets around 8/9 pm, in summer around 11 pm, in winter around 7 pm...
I think the site is called Sonnenstand.de where you can play around.

A utility room facing NE means long and expensive supply routes, I wouldn’t do that. I would place it facing SE, like the carport. Entrance in the south and the living area as an L-shape to the west, with the living room in the north, kitchen and dining to the west with large south and west windows. North somewhat smaller.

I find the drafts horrible, you can gladly have them discussed further.

in winter at 7 pm...

You are an optimist. I'll remind you again in 3 months :-p

I find the drafts awful, you can certainly have them discussed further

Compared to others, they are not that bad - at least regarding the basic layout of the rooms. Personally, I like neither the house style nor the roof shape. However, both (e.g. this pseudo-bay window) influence the room design. I would definitely make the carport 9 meters long: in the rear (northern part) then an integrated shed for the garden stuff.
