Floor plan planning single-family house / bungalow - 155 sqm

If the single-story design is desired by the authority, but there is a slope throughout the entire building/residential area, in my opinion it is a good statement of the development plan to at least allow the basement to be built as a full floor.

Basically, I agree, but 1.20 m is simply not even half a floor. A basement would quickly protrude more than 1.40 m above the level and then would hardly have anything to do with a cellar. With this gradient, a bungalow should be just possible. In the north corner, the window sills then end flush with the turf. (I hope I read it correctly: the slope drops 2.60 m from north to south across your property? Otherwise please correct me – in which corner is your highest point?) However, an entrance in the northeast would again require quite a bit of excavation with supports for the path. An entrance in the south would probably be more favorable. Sketched here, with the natural terrain intentionally left unchanged to get a feel for the terrain.




However, with the distances and your giant bungalow, in my opinion the garage will be tight. You can’t reproduce everything exactly, but from the overview you can already see that it’s problematic with a 4 m free driveway. The garage here measures 6.20 m as an outer square dimension. And your bungalow does not yet even have the 40 cm outer walls, right? So about 40 cm is still missing from the 17.4 m. That’s quite a monster.


I couldn’t warm up to the bungalow with 3 kids + study anyway. I see this much more as a normal single-story house with an expanded attic. Of course, one would have to know more precisely from where the 9 m height applies and what maximum roof pitch is actually permitted? Therefore, here again is the question about the previously rejected drafts with reasoning.

Here I come again with my favorite example, the "Split Down" by Laux, as a suggestion (no, I really have nothing to do with them). That should actually fit quite well with a 1.20m slope. Although with 3 children, I would really plan a 2nd shower/toilet. The style of the "Starline" by Laux could also serve as inspiration. Here, the basement is about 50% "buried" in the terrain. The house is rather small with 130m2 for the wishes here, but still suitable as a source of ideas.

A UG would quickly protrude more than 1.40m above the ground level and then has little to do with a basement.

That’s why it’s not called a basement but a developed lower floor ;)
It won’t be a buried city villa, but simply a single-family house where the “basement” may protrude more than 1.40m on average. You also shouldn’t forget the attic, as it can also be used as a non-full floor. Although that’s not the original poster’s intention, I’m also not a fan of inflexibility when so much is already allowed and possible.

Nice example house for split level! I like it! And it also looks affordable - SL is otherwise more or less a good way to sink costs in the architect scene ;) Here you could go a bit wider/deeper, the plot allows it. Then without a basement.

Well, this is the standard for split in my opinion and totally unspectacular. But without a doubt:

..it still looks ... affordable

The problem with split in my opinion is that you can only build something like this with companies that have done it dozens of times. But maybe you can get a bargain with prefab house providers who offer this in the standard segment compared to other providers.

I also find the example house Split-Down very good and so far the best proposal for your plot! The view from the bedrooms certainly has something special, and in general, it makes sense—as has been mentioned here many times—to adapt the house to the plot, not the other way around! I also think that you are on the wrong track with a five-room bungalow. We are building a bungalow with 140 sqm for two children and an office, and that is already a big box, and with one more room, we probably would have passed on it. But we only have "just" 770 sqm.

For the floor plan, we also initially wanted it American-style and go straight into the living room, but then quickly discarded that and instead focused on more privacy. If desired, I can share it here sometime, but I think you should rather let go of the idea...
