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

the mini-split

No mini-split. Simple slab-on-grade house... or, Katja?

By the way: antwortet ihr beide unter einem Account?

Yes, we do. Otherwise, it would certainly be confusing for those reading along.

Actually, two base plates are planned here. The idea is to soften the moderate slope a bit without needing a real screed right away. Maybe it's also cheaper to just make one plate and pour more screed in the upper area? Depending on what is cheaper. I added a bit to the external dimensions because the knee wall at the top takes up so much space. I have to measure tomorrow. I'm going to bed soon...

You should hire a surveyor

I generally think that's a good idea ;) . Just kidding aside, such an elevation plan is always useful, whether for the building permit, the potential architect, etc.

there is a dedicated application to determine your elevations with a hose or something.

The thing is called a water level. It's simply a hose filled with water. I believe there are quite good videos about it on YouTube.

For me as a surveyor, the question now is whether you want the absolute height (above sea level). That's not so easy without a surveyor. For a surveyor, that's absolute routine. It should cost around 300-500€. But with the plan, you can do a lot.

As a surveyor, the question for me now is whether you want the absolute height (above sea level). That is not quite easy without a surveyor. For a surveyor, it is everyday business. It should be around 300-500€. With the plan, you can do a lot as well.

Hiring a surveyor actually sounds like a good investment! We will push that forward.

, I still have in mind that your sketches were roughly 100+80 sqm in size, which could still be reduced by about 10 sqm with a sharp pencil.

Do you think this implementation is more likely to be within our budget, instead of the bungalow mentioned at the beginning?

Well, that’s a good question. The expensive part about a slope compared to a flat plot is the terrain modeling. If you want to place something large and flat on a slanted surface, you have to move more fill material back and forth than if the area is smaller. That’s certainly logical. Then there are the many supports, which are not free either. The more you build into the slope, the less you have to move and support. But you will certainly never get around it completely. The roof on the bungalow is also a real cost factor. It’s simply huge. Two floors need only half the roof area (roughly speaking). A staircase is also cheaper than two roofs. The question for you is also, what do you need? 155 sqm for 5 people is rather tight if you also need an office. Yvonne nicely calculated it in #48. Actually, you need the 180 sqm. A 155 sqm bungalow will ultimately surely cost you more or just as much as a 180 sqm one-and-a-half-storey house. Prices are currently very unstable, but it feels like you’re missing 100K – no matter what you build. It only gets cheaper if you reduce the wish list. I also have to ask quite bluntly: if your budget is already tight now, how is it going to be with 3 kids? I have my doubts about that. Ultimately, we sadly cannot tell you what the companies near you charge. The only help is to ask. ;)
