Single-family house with a basement on a hillside - Opinions (roof shape, general)

If you change the direction of the stairs, you get the shower bathroom in the basement under the stairs at the exterior wall and can put a window in. Light would also come into the hallway in the basement through frosted glass light strips in the wall from the stairwell to the bathroom. Also, the "Kellerabgang" would no longer be directly next to the main entrance door...

Is the slope so steep that it spans 2 stories?

Draw the furniture in all rooms to scale once. Especially in the bathroom and take the rough construction measurement of the shower.

The shower would now be 90 cm wide

The garden access is missing in the basement. The advantage on a slope is that you can always get out everywhere.

That’s true, but we soon discarded that again because it would mean additional hallway space ---> house even bigger The basement is unfortunately almost half underground, so we have to make sure each room gets enough daylight. The window in the larger children's room will be executed as a balcony door as planned. Then at least there is the option to get from the basement into the garden.

You say nothing about the age of the children. You have a relatively small terrace for eating upstairs. Garden access downstairs. For me an absolute no-go. Are the children supposed to go around to get themselves a drink? I would remove the bay window, have a large terrace in front of the ground floor, possibly push the basement forward and use the cellar better. It is there and it is paid for.

Children are planned (2-3) Do you find a 20 m² terrace upstairs too small? That’s why the stairs from the upper floor lead directly into the garden. We also considered pushing the basement forward, but it is not simple because then part of the ground floor in the rear would be partly in the air. Then we would need a foundation again. And to enlarge the entire terrace, it already becomes quite large, which is also associated with costs. The bay window adds an additional orientation towards the south/west with a view of the mountains. But as planned, the version can still be improved and solved differently. We want to use the cellar better in the future, not fully renovate it immediately but provide everything for it. Possibly a studio for a child, guest room, hobbies, ...

Try to make the lower part of the garden accessible for wheelbarrows, sack trucks and co. The stairs are not so great for carrying. Whether flowerpots, lawnmower, the bag of mulch, grass clippings, swing - it all has to go from top to bottom. Plan the outdoor area as well. Now the excavator comes in, later it will be more difficult

Thanks for the hint, we will plan that more precisely again as soon as the rest is roughly final. An idea for this would be to lay a path or ramp on 2 levels on the garage side to get down there with the wheelbarrow etc.

Is the slope so steep that it spans 2 floors?

Yes, the total height from street level to the flat area below ("original terrain") is now 6.4 m.
With a slight incline up to the garage/front door and raising the garden by about 0.5 m using the excavation, 3 floors fit almost exactly.
For your information: The terrain shown is currently still the "original terrain"; nothing has been adjusted so far.

Personally, I also prefer a gable roof variant, especially since most buildings in the neighborhood also have gable roofs.

From the terrace down, a 'Table lift' can be installed, making it easy to get groceries downstairs.

To be able to eat on the terrace upstairs with 4 people, it should be at least 250 cm deep.

For the children, a slide instead of the stairs :)

In the garden room downstairs, definitely plan sanitary connections & electricity (empty conduit) for the kitchen; or lay connections for an outdoor kitchen right away - otherwise, the garden will hardly ever be used except for the sandbox.

I never had separate garden living in the baby/toddler age anymore. 1. Children live outside until the WiFi age comes. 2. You can't have children unattended for a long time. So you pack toys, drinks, drag the stuff down the spiral staircase with a 1-year-old in your arms. Damn, forgot the diaper. Pick up the child again, back down again. Quite exciting with two. Children are already 3 or 4, you can leave them alone for 5 minutes or cook/housework, it’s enough to be within hearing range and check every few minutes. It doesn’t work. So you squeeze the paddling pool and micro sandbox upstairs and pray not to have a climbing fanatic.

I would really consider rearranging the rooms. Even with a few friends and a barbecue it gets cozy. With the terrace and eating/cooking upstairs you build in disadvantages of an apartment. A floor that is hardly used later maybe. Shame.

Try downstairs with cooking, eating and on the ground floor a living room for quiet. 1. You have garden access 2. You have a view upstairs - if you ever have quiet 3. You as parents have a retreat.

Gable roof is better. The extension looks like a retrofitted elevator on an apartment building.

Shower with 90cm shell dimension is very narrow. In the end, it can be 85cm. You are at '80s shower tray width. Look at it and see if you want it. Always really draw the complete furnishing to scale.
