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!
Development Plan / Restrictions
Owner’s Requirements
House Design
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

...on one side, you end up with a bungalow. You have to like that, and I don’t see that with Franky here. Oh, do you think so? I thought that’s exactly what he wanted.
If I understand correctly, two full floors are desired here, with the entrance level not being counted because it does not protrude that far above ground on average. This might be possible if the slope (within the building plot) is sufficiently steep – but then it would result in a fully buried uphill side (meaning mostly air shafts rather than light shafts, practically unsuitable for living spaces).
This is a task for hardcore math enthusiasts and requires exact height measurements.
I would be more inclined to consider whether a sloped roof is really such a problem.

Yes, I also find it hard to understand why people can’t accept a gable roof house with a knee wall. Or a shed roof, which actually invites a slope.
The problem nowadays is that people don’t accept a plot of land with its natural terrain as a gift and build something beautiful on it; instead, they have a fixed idea of a house shape in mind and impose that on their land almost like a mortgage.

I overlooked it because I was only using my phone:
The legend of the development plan only allows gable roofs.
And here I want to advise Franky again:
1. Look at the plot, 2. read the development plan (building permit / planning permission), 3. consider whether you can accept the requirements of the development plan. If yes, then calculate (possibly with a soil survey and/or architect) how much earthwork is needed, 4. buy the plot.
After that, don’t plan for or favor something that is not allowed or does not exist.
This discussion is more or less pointless.
And without criticizing Katja’s design: for a sloped plot, there will be other designs that fit.
I just read: the plot is already purchased…
So reconsider your requirements for your dream house and then share a cross-section including a photo and site plan of the plot.
If you’ve owned a plot for two months, you probably have a hand-drawn sketch with dimensions of the plot and are moving rectangles around.
So share that, and then we can move forward.

The legend of the zoning plan only allows gable roofs.Where did you find that? I’m too dumb to see it.Maybe something like this:
A certain resemblance to the original can certainly be seen. Assumed 1m (3 feet) knee wall. On a slab foundation – slightly built into the slope on the north side (bottom of the plan), raised on the south side. Of course, I don’t know if that’s feasible.
