Hello everyone,
Two months ago, we purchased a serviced building plot on a hillside and are currently deeply involved in the floor plan design, which is proving quite challenging due to the elevation difference.
I have been following the forum for a while and recently found a great template for our project that I think just needs some adjustments to fit our requirements. I would really appreciate your feedback and am, of course, open to criticism!

Owner’s Requirements

If you have to give up something, which details or features
Why does the design look the way it does?
We really like the design here by "kaho674." It truly reflects our ideas. The upper floor should still fit now but, of course, with our minimum required room sizes and the requirement to build only 1.5 storeys.
What is really important to us, especially since the plot is on a slope — the highest point at the street is just under 1m (3.3 ft) above the zero level and it drops 5.11m (16.8 ft) to the lowest point — is how everything can be integrated into the plot without the costs for filling and leveling running out of control. We have also considered an alternative to the urban villa in the style of a split-level house. What have your experiences been building on such a plot?
Many thanks

This thread is driving me crazy... the accident metaphor fits quite well, the original poster should be very grateful that Katja has such patience and mindset...Huh? What does that have to do with me? I’m just enjoying my hobby.M
Matthew0317 Jul 2018 14:19Yes, Zaba and YPG did that as well, but both have dropped out, unlike you. Hence the note about your patience...

Yes, Katja’s design remains the foundation for us – you’re right! For the start, we first need a foundation for the next steps, as I advised you. It can also be the design from #319 if you prefer, but the current state is not yet about achieving perfect single-story construction.

Great way of putting it again with "Get your ass in gear!" I completely agree, just expressed differently. Continuing to debate whether it’s offensive or well-meaning to accuse you of naivety or laziness won’t bring you any closer to the cornerstone laying – but it will surely further reduce the number of participants in the discussion.

P.S. When I scroll, the word "team leader" always jumps out to me on the left in the profile... and I can’t help but wonder if this "style" is also applied to "leading the team". Team basically means: great, someone else is doing it.

There are some amusing automatic right triangle calculators online. When I enter a 5m (16 feet) slope over 38m (125 feet), I get about 7.5°. If I convert that to a 10m (33 feet) house length, I end up with a height difference of 1.30m (4.3 feet) over the 10m. So, I could dig the house 1m (3.3 feet) into the hillside and build up 30cm (1 foot) at the back, right? I would also cut in a bit on the sides. Is that unrealistic?

No idea. The areas under the slopes are only counted at 50% up to 2m (6.6 feet) in height. That's why with gable roofs, the footprint often seems larger. I haven't calculated it yet, and my software can't do it either. But yes, I’m afraid with 140 it will start to feel tight. That’s what I meant—you want a walk-in closet, bathroom, two children's rooms, plus a bedroom upstairs, so the square meters add up quickly. Okay, thanks. By the way, in the bathroom there was an empty space on the far right side—what is that for? Probably because of the knee wall height, right?

Franky, with a sloped site, I would consider moving away from a "conventional" floor plan. Since the slope is quite pronounced, a split-level design might not be the best choice (but you could take a look at matte’s house here, which to me is a brilliant split-level solution).
Still, the slope can be used to your advantage. Without more specifications, this basic idea comes to mind:
Very schematic: two levels shifted against each other. If I understand correctly, the lower level would need to be built quite deep into the ground (shown here by the red line indicating the terrain), and to comply with the building regulations / planning permission, it might also need to be built further into the ground on the sides, meaning windows only at the front.
Advantages include likely needing less earthwork and having an amazing terrace on the upper level while still getting sunlight downstairs (with a balcony, the area underneath tends to be darker). From the street, only one level is visible. The whole structure can have a modern look with a flat or mono-pitched roof (if allowed by the building regulations / planning permission), or, as I understand you prefer, a more traditional design with a gable or hip roof on top.
If done cleverly, you can access the garden directly from the large terrace, especially if the lower box is set a bit deeper into the ground.
Just a thought, without a proposal on the room layout or anything. But in my opinion, this would make optimal use of the plot without forcing a house designed for flat land onto a steep slope, which usually leads to poor compromises. That’s exactly what I meant a few days ago! I also did some research (so I don’t get negative comments here again), and what I had seen included two overlapping mono-pitched roofs. One was longer, the other shorter, and they met at different heights. This also allowed part of the terrace to be semi-covered.
