Construction costs are currently skyrocketing

Such a tightening is slowly turning off the tap for monolithic construction. KFW 55 is still possible, but after the tightening comes the next tightening, and with KFW 40 the air gets thin for Poroton and aerated concrete. Thick wall constructions are the result and it also gets significantly more expensive compared to ETICS.

That much difference doesn't make a difference for aerated concrete now. With 36.5 you can just barely reach EH55, with 42.5 you are at EH40. Sure, it's thicker and more expensive but three fingers thicker is not the end of the Western world. Our general contractor had 40cm as standard (they are available for aerated concrete), where the difference is even smaller. None of the regulations really make sense. The few kWh you save with it are bought at a high price and hardly pay off without subsidies. Accordingly, it is better to invest the subsidy money in renovation where you can still relatively easily gain 50 kWh/sqm upward instead of shaving another 5 kWh/sqm off new construction.

A couple of friends received a letter from their preferred main contractor. He is currently not signing any new contracts until the maintenance window of Nordst....1 is over and it is clear whether deliveries will continue or not...

Oh man, that really scares me. We will only talk to our main contractor in August to see if the shell construction can start in October.

Would like to have some of the problems here. :p Owning a property would be a nice start to even be able to think about planning somehow. At around 2% interest, we might still be able to build something... :rolleyes:

If building with ETICS, the discussion is ridiculous. It basically comes down to 2 cm more or less insulation on the wall. But such a tightening is slowly shutting the tap for monolithic construction. KFW 55 is still possible, but after the tightening, before the next tightening, and with KFW 40 the air gets thin for Poroton and aerated concrete. Thick wall structures are the consequence and it also becomes significantly more expensive compared to ETICS.

You can very well build KfW 40 and KfW 40+ monolithically. This is also done by our company KB Brandis. The jump to KfW 40 is not that big. In our case, the exterior wall would only have to be slightly thicker (42 cm instead of 36.5 cm) and a few things would still have to be adjusted. Windows are already suitable for passive houses, we already have controlled residential ventilation, photovoltaics, and a geothermal heat pump. I think the costs would amount to about €10,000 - 15,000 for us. Whether KfW 40+ would be possible monolithically with a bungalow, I am not quite sure.

I think the costs would amount to about €10,000 - €15,000 for us.

That’s pretty close if only the stone has to be thicker... Without subsidies, you would probably have to live to be 450 years old for it to pay off...

I’m surprised that this argument only ever comes up with insulation. How much does a kitchen cost today and how long is it used? How often could you eat out? How long could you pay rent until a house pays off? How often could you take a taxi until owning a car in the city pays off? Monolithic construction would be more sensible in terms of the sustainability of the building materials and their lifespan than all the composite materials.
