What actually comes out as savings, of course, still needs to be determined, I know that too.
On the other hand: If the living area is still about 150 sqm, where should one save? Building without a basement on a slope makes little sense. Okay, I could completely omit the garages. I don’t want to, because of the martens. Otherwise, as I said, there is no luxury! No photovoltaic system, only air-to-water heat pump, no ventilation system, etc.
However, it may well be that the offers the architect has are unrealistic – overall. But I don’t really believe that. It is what it is – everywhere the order books are full, the material prices are on top. We are simply one year too late.
