Construction costs: Single-family house in Baden-Württemberg 2019 (KFW 40 plus)

And to contribute something to the topic, our architect calculates at a good standard (approx. KfW 55 to slightly better, but we are building without KfW standard) with 450€ per cubic meter.

There you go, the OP would be quite a bit away from the 600k.

I want to see the house with 1000 cubic meters and 150 sqm with a basement. How high are the ceilings supposed to be there, 3 m clear height?

We have 1275 with a net floor area of 120 sqm floor area per floor, with above-average room height.

You do know that enclosed space includes the walls and ceilings, right? 150 sqm plus basement is pretty much exactly 1000 cubic meters.

Well, that would mean the OP is quite far from the 600k.

You don’t get it.

For 1000 cubic meters, that’s 450,000€ in KfW 55, not 40 or 40 plus.

That doesn’t include ancillary building costs, no architect, no garage, no landscaping, and no fittings.

You do realize that enclosed space includes the walls and ceilings? 150 sqm plus basement is pretty much exactly 1000 cubic meters.

Yes, including the floor slab. I would suggest you sketch the measurements again on a sheet of paper and recalculate...

I just recalculated, it’s only 1200 cubic including 55cm attic.

Yes, including the base slab. I would suggest you sketch the dimensions again on a sheet of paper and calculate... I just recalculated, it’s only 1200 cubic meters including 55cm parapet.

Okay, I’ll leave it now. I don’t know what you’re trying to tell me since you even get more cubic meters out, nor what you base it on and which house you take because you talk about a 55cm parapet. First you say it can’t be, you need 3m ceiling height, then you come up with 1200 yourself?? There are houses with the same living area and very different cubic meters.

Thank you very much for all the suggestions! We have decided not to build a basement. In the meantime, I have also revised the budget based on your suggestions.

House (turnkey): 375000
Additional construction costs: 75000
Outdoor area (clearing the plot, access paths, and terrace): 50000
Carport: 20000

//Furniture and kitchen have a separate budget.
