ᐅ Floor Plan Design Single-Family Home, 1.5 Stories, 150 sqm – Feedback Welcome

I’ve oriented the plan to the north and drawn in the house.

It already looks quite good. There are hardly any alternatives within the building area.

There is about a 1 m (3 feet) height difference in the house area. I’m curious to see how the planner will handle that.

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

Dear @SoL, I don’t understand what you mean!
TE seems to be well informed about the plot – no more and no less.
Regarding the “slope”/1 meter… isn’t that something you usually mention?
As for house costs and 70% in EL… that’s not really considered realistic either. I find your comment misleading. It seems to show more certainty than is appropriate.

Here, I was only referring to my idea for the room layout, so I didn’t address what, from my understanding, is the slight slope. By chance, the company we visited today is going to build a house just 100m (330 feet) away, and they really have a slope (estimated about 10m (33 feet) drop over 25m (82 feet)), so when I drove past, I was already wondering how you’d place a house there. I’ve seen the plans and, as far as I can tell, they did a really good job.

Maybe I should have mentioned that this won’t be our first house. We have already completely renovated an old house. In that house, apart from the screed, heating system, front door, and windows, I did everything myself. I removed walls (including load-bearing ones based on a structural engineer’s calculations) and replaced them with 200x200mm (8x8 inch) oak beams, installed new drywall partitions, plastered, filled, lowered the entire ceiling (partly including insulation and vapor barrier under the roof terrace), tiled, installed new water pipes, fitted sanitary fixtures, completely renewed the electrical system including a smart home system, installed all new room doors, replaced basement windows, reactivated the old chimney and connected a panoramic fireplace (which was approved without issues by the chimney sweep as I involved him at every step), laid pipes for a central ventilation system, and certainly did some other things I don’t recall right now. So I know what it means to spend 15 months going to the construction site every day after work, every weekend, and the entire vacation to work hard. I made many mistakes that cost me time, but from those, I learned a lot, and in the end, the result was quite good. Due to personal circumstances, we decided to sell that house and now want to build our dream home on the new plot.

For those concerned, I know from my studies not only the theory behind electrical work but also, thanks to my profession (even if it’s not usually related to houses), I am actually allowed to carry out these works.

So when I say I could do everything myself except for screed and heating, I mean everything except the shell construction. Once the shell is on the base slab, the windows are installed, and the roof is covered, I could take over. It is definitely not my goal to do everything myself, but I prefer to invest my time and energy in the house rather than accept compromises by having a turn-key build full of concessions. I’m definitely glad that this time there is no demolition involved; scraping off 60-year-old wallpaper layers, removing over 60m³ (2,100 cubic feet) of construction debris and an additional 30m³ (1,060 cubic feet) of other waste already took a huge amount of time and effort.

I am curious as well. I briefly considered whether it might make sense to partially cellar the house and place the technical equipment and garage there. However, since we want to live barrier-free in the house when we are old and frail (at least on the ground floor), having the bedroom and bathroom on the ground floor is very important. If I already have to climb stairs to get from the garage into the house, that would completely defeat the purpose. I currently assume that they will add some backfill under the garage and the northern part of the house and then create a natural transition to the creek beds. This might also have the advantage that the excavation soil from the base slab would not need to be disposed of at additional cost.

One more question: does anyone have experience with dry screed, especially in combination with underfloor heating? The planner today said that in their houses dry screed is usually installed because with a timber frame house and traditional screed, you need to be careful during drying. It’s not impossible, but apparently, quite a few mistakes can be made.

Yes, a thankless task.

Well, there’s more than just black and white 😉

And such thoughts or questions could possibly be resolved by the forum community if you share this information in the forum along with your question.

Oh! I wouldn’t have thought that!
A bathroom of 7m² (75 sq ft) and a toilet of 3m² (32 sq ft) can hardly be barrier-free.
I don’t see that mentioned in the completed questionnaire either, which should at least encourage some reflection.

When dealing with a house and renovations, one should know that walls and wall thicknesses can change a lot.

I was considering a split-level design before the accessibility requirement was introduced.

@Narma89 I can relate to your renovation, as we are currently in the middle of the same process and will also be installing a dry screed with underfloor heating. Unfortunately, I don’t have any experience to share yet, but I’m happy to hear about yours 🙂 Wishing you lots of success with your new project!

Here is the version with the terrain modeled.

Level 90 m (295 ft)

Green: fill material including the slope

Yellow: cut area shown without the slope. The slope then extends to the property boundary.

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

The piping in the trench needs to be extended.
