Suggestions and ideas regarding our floor plans are welcome

Here are the other two views from architect Münz...

This is our first draft hand-drawn by the architect. Old school, nothing CAD . Everything we didn’t like we had changed. That means pantry door, guest WC, guest room, no light shaft, etc. It’s 138 sqm plus basement which with slope surcharge and outdoor area, basically only group 300, 400 & 500 about €370k. So without land, preparation and development, equipment including sanitary, incidental building costs according to DIN276) So quite a lot is still missing. Well estimated, an additional €50-60k will be added to the €370k.

What do you mean by "group 300, 400 & 500"???
You’re building ground floor + upper floor,... and therefore the 138 sqm? I already come to 83 sqm on the ground floor alone (without stairs)...

An 80-90 sqm usable basement for an additional 25k? Do it, immediately. Can you bring me one?

You notice, some people here are (in my opinion rightly) rather skeptical. With a basement, you obviously don’t need the attic anymore, that should be clear. But then you have to plan a closed basement access, and whether that looks good in the living/dining/kitchen area. A matter of taste. But those are probably more like details later on.

I don’t even think the upper floor is that bad, although I see a bit of wasted space in the bathroom. Operating on the stairs, however, is always like open-heart surgery. The floor plan can make or break because of that.

Aside from the technical aspects, what exactly do you not like about the floor plan? It’s not that bad. I think it definitely has potential. But you don’t seem to like it that much.

You misunderstood me 25k€ and up and no area... Sure the basement cost more (60K), but in return you get more space and on the north/west side no thick concrete slab on the house wall.

Apart from the technology, what exactly don't you like about the floor plan? It's not that bad. I think it definitely has potential. But you guys don't seem to like it that much.

It's quite okay as it is, but if I swap the kitchen and living room, the space somehow doesn't work...

Do you see wasted space upstairs in the bathroom? Where exactly?

Currently, the shower is above the passage to the technical room...
That is gone on the floor plan you adjusted.

Thanks for your effort!!!

PS: I think we have to do a lot ourselves to push down the price

One more question in between.... (opinions on this really differ) Thinner masonry and insulation instead? Or 42 cm masonry and no insulation??? I am currently on the way to planning without insulation... And KfW hardly/doesn't pay off anymore (especially with a lot of own work anyway)

Please take a look at the attachment... Access is not a problem.

That’s exactly where I see a problem: at least with the two developer drafts, you need a Smart or a Goggomobil to be able to drive forward into the garage and also drive forward out of the dead end back onto the main street.

The search term WDVS should lead you to several forum posts from last year where everything has already been said on this topic. You’ve already summarized the result correctly: "this divides opinions" – and repeating the question won’t change that. If you want to build monolithically, 36.5 cm will probably be sufficient – after all, you’re not planning gigantic window fronts.
