Certainly depends on the house as well. But we have a house from the 80s and 150k probably isn't even enough for 70ee :) Own contribution is not supported.

Are you able/willing to insulate the basement floor? How is it then in terms of room height?

Absolutely... Just for comparison: Bringing our single-family house from 1930 with 200m² to KFW 55 was estimated by our architect at 300,000 - 350,000€ after KFW subsidies. Well, we also had a renovation included, for which I would deduct 75,000€. But the bottom line remains: Renovations are expensive.... Postscript: We are currently heating (January over 24 months completed, so already after gas price inflation) for 300€/month. So purely from the heating cost side, something like this is at least not worthwhile for us...

Remove existing screed, rebuild floor according to specifications, remain 2.1m.

But then certainly not with a floor construction for 40. Or do you already have a room height of over 2.35m? For 55, I needed a floor construction of 20cm – and that with PUR insulation.

If there are three residential units or more, does one not fall into a different building class and thus have higher requirements for the building, such as fire protection, …? Surely every federal state has its own regulations for that.
