Information from the web (including this forum) and contacts with other builders
What makes it especially good or bad in your view? Don’t know

What is the most important / fundamental question about the floor plan summarized in 130 characters?
Because of this forum, the building shell is planned as it currently is. The lower residential floor is to be half embedded into the slope on the valley side. On the open side are the two bedrooms and the main entrance. To the right, the double garage, also partly embedded in the slope. In the slope are the utility room and a bathroom. The ground floor above is planned entirely for living, with terraces and garden access, plus a small bathroom.

Fire away and thank you all.
Plan top is north.

Site plan: green plot 162/163, surrounding plots, roads, and buildings.

Lower floor plan: bathroom, utility room, hallway, bedroom 1, bedroom 2; green marked room 12.


Apartment floor plan: green marked living area with hallway, shower/WC, and kitchen.

If I built the house as you have drawn it, the house would be partially embedded into the slope on the short side.

This way, the basement level could even have windows facing three directions (east/south/west).
An integrated garage is not the cheapest solution, but it might be worthwhile in this case.
Rooms + shower bathroom + entrance + garage in the basement, living + sleeping + bathroom on the upper floor.

Relocating a light pole is costly. We paid around 4,000 (currency) and that didn’t include transport or storage. It covered only dismantling, cable laying, reassembly, and connection.

Your south-facing bedroom won’t really stay cool. It’s better to choose the upper floor and face northwest. In modern houses, the temperature difference between floors is not significant; it’s more noticeable between south and north sides.

I find 11an’s suggestion with the garage very appealing.

Sofa with its back to the window: When we watch TV, it’s usually late in the evening, so it’s dark outside. There’s not much to see then. We have planned a daybed in the dining room in front of the fixed panoramic window.

Then just call it the TV room 😀

The “child” is 19 years old and won’t be living with us much longer anyway.

That was exactly our challenge when building—that’s why it even crossed my mind. Kicking the “child” out of the utility room with some noise is obviously another solution.

That’s how we solved it.

Good point.

@ypg Now my confusion is confused.
Confused or clarified?

The south slope descends quite evenly from north to south.
Yes, but we don’t actually know that. In your 3D view, there is a steep slope visible. With the software you are using, you can model a slope across the entire width of the plot.
Why is the plot modeled so extremely? Because of the terrace? I would always suggest the most straightforward (and usually most cost-effective) approach—given your idea, I would rather place the garage beneath the terrace...

Exactly! About one-quarter of one floor embedded. With a “regular” house, having an entrance on the ground floor and a terrace on the ground floor... that’s better than embedding half a floor.

How about presenting one—the plan WITH elevation details?

So, I visualized this (not as polished as a professional program, but understandable).

I roughly mapped out the contour lines, assuming the 2.50 m (8 ft 2 in) height difference within the building area (I took the front part of the plot) is distributed evenly.
I created a building volume similar to your house. The windows are just symbolic to show how much house you get on a slope.
Regarding the garage, I would even suggest placing it on the east side in front of the house... maybe I will visualize that shortly as well.
Slope at the front, possibly with retaining structures, and the same at the back. I used both examples.

White two-story house with black roof, terrace, garden, and one person on the left.


Two-story gray house with dark roof, garage, garden path, and standing person on lawn.


Garden layout with central house, terrace, gardens, garage, and driveway.


... and if my little figure doesn’t want to float but rather use stairs, then probably only towards the north terrace 🙂
