Floor plan design single-family house, 1.5 stories, 150 sqm - Opinions wanted

I have oriented the plan to the north and drawn in the house.

That already looks pretty good. There are hardly any alternatives given the building zone.

In the house area, there is about a 1 m height difference. I’m curious to see how the planner will solve that.

If the new survey plan differs, you can anonymize it and then post it here.

Dear , I don’t know what you mean! TE seems to be informed regarding the property – no more and no less. Regarding the topic "slope"/1 meter... doesn’t one mention something like that? The subject of house costs and 70% in EL... is also not something considered realistic. I find your post misleading. It could show more confirmation than is appropriate.

Here I was only talking about my idea of room planning, so I did not address the (for my understanding) slight slope. By chance, the company we visited today will build a house only 100m away, and they really have a slope (estimated about 10m difference over 25m), so driving by I already wondered how one would want to put a house there, and I have seen the plans and it looks really good (as far as I can judge).

Maybe I should have added that this will not be our first house. We have already fully renovated an old house. In that house, except for the screed, heating, front door, and windows, I did everything myself. I removed walls (including load-bearing ones after calculation by a structural engineer) and replaced them with 200x200mm oak beams, installed new drywall walls, plastered, filled, lowered the entire ceiling in the house (partly including insulation and vapor barrier under the roof terrace), tiled, laid new water pipes, installed sanitary fixtures, completely renewed the electrics including smart home system, installed all new room doors, renewed basement windows, reactivated the old chimney and connected a panoramic fireplace (which was also accepted without objection by the chimney sweep because I involved him in every step), laid pipes for a central ventilation system, and certainly a few other things that don’t come to mind right now. So I know what it means to go to the construction site and work every day after work, every weekend, and all vacation for 15 months. I also made many mistakes that cost me some time but through which I learned a lot, but in the end, the result was something to be proud of. Due to private circumstances, we decided to sell the house and now want to build our dream house on the plot. For all the skeptics, I know from my studies not only theoretically but also practically through my profession what I have to do with the electrics (even if I usually don’t work on houses) and am authorized to carry out these works.

So when I say that apart from screed and heating I could do everything myself, I mean everything except for the shell construction. Once this is standing on the foundation slab, the windows are in, and the roof is covered, I could take over. It is definitely not my goal to do everything myself, but I’d rather invest my time and energy into the house than make compromises and have a turnkey house full of compromises built. I am certainly glad this time that demolition is not necessary; scraping off 60-year-old wallpaper layers, removing over 60m³ of construction debris and another 30m³ of other waste from the house cost a lot of strength and time.

Within the house area, there is about a 1 m height difference. I’m curious how the planner will solve that.

I am indeed curious as well. I briefly considered whether it might be sensible to partly cellar the house and put technology and garage there. However, I want to be able to live barrier-free in the house (at least on the ground floor) when we are old and frail, which is why the bedroom and bathroom on the ground floor are so important. But if I have to climb stairs to get from the garage into the house, that would be completely counterproductive. I currently assume that under the garage and the northern part of the house, there will be some embankment and then a natural transition to the streams will have to be created. That could also have the advantage that the excavation for the foundation slab would not have to be disposed of at cost.

One other question, does anyone have experience with dry screed, especially in combination with underfloor heating? The planner today said that their houses mostly use dry screed because with a wooden house and normal screed you have to be careful when drying. It’s not impossible but apparently one can also do quite a lot wrong.

I am definitely glad that this time the demolition is omitted, scraping off 60-year-old wallpaper layers, removing over 60m³ of construction debris and another 30m³ of other garbage from the house has already taken a lot of strength and time.

Yes, thankless task.

It is definitely not my goal to do everything myself, but I prefer to invest my time and energy in the house rather than making compromises and having a house full of compromises built turnkey.

Well, there is more than just black and white ;)

I briefly considered whether it might make sense to partially basement the house and accommodate technology and garage there.

And such thoughts or questions could possibly be solved by the forum community if this information and the question are posted in the forum.

Oh! I wouldn’t have thought that! A bathroom of 7 sqm and a toilet of 3 sqm cannot really be barrier-free. I also don’t read anything about that in the completed questionnaire, which should actually stimulate some thinking. If you are dealing with the house and renovation, you should know that walls and wall thicknesses can change a lot.

I was thinking of Splitt Level before the restriction [Barrierefrei] came.

I can empathize with you on renovating, we are currently right in the middle of the same program and will also be laying a dry screed with underfloor heating. Therefore, unfortunately, I cannot offer any experience, but I am also happy about such :) Wishing you a lot of joy with your new project!

Here is the version with the terrain modeled.


Level 90 m

Green fill with slope taken into account

Yellow excavation shown without slope. The slope then extends to the property boundary.

The driveway has a 10% decline and then an incline.

The piping in the trench must be extended.
