Hello everyone,

I hope to gather some experience here.

We are currently planning our own construction project in Rhineland-Palatinate. We would like to use the KfW 300 program with QNG certification to receive the €220,000 grant. The plot of land is already secured. We had a consultation with Hanse Haus, and I have to say I was shocked by the price: €580,000 for 160 m² (1,722 sq ft) turnkey. The consultant said they can only offer a custom design because it involves boundary line construction. According to him, we ourselves cannot do anything to meet the QNG certification except some minor painting work. He calculated roughly €3,000 per m² (approx. $280 per sq ft).

Additional construction-related costs are estimated at €30,000, the garage at €10,000 (does this need to be included in the cost breakdown?), and the garden also at €10,000 (which the consultant said must likewise be included in the cost estimate).

Does anyone have experience with similar projects or can recommend another provider? We are currently still waiting for a quote from Massa Haus. The price is definitely too high for us, and with that, the subsidy doesn’t really make sense.

I would really appreciate any responses and help.

Best regards,
Leon

You say the price is normal, but on the other hand, you say it cannot be assessed. You are contradicting yourself.

What do you want now? Should I respond further, or is my opinion unwelcome? I don’t understand how I am spreading a bad mood. At most, the truth might be painful, okay.

To be more specific again: the 3,000 per square meter (approximately 280 per square foot) is currently the standard market price for a basic house without extras, on flat land, detached, and far from any other special problem cases.

You want to pay more because of the QNG. But we don’t know what else is included in the offer. It could even be very inexpensive if additional work or features are included.

Which provider would be the right contact? Do you have a suggestion?
You can either consult an architect to design something tailored to your specific situation and then put the project out to tender. Alternatively, you could go to a local general contractor who handles both planning and construction (though this depends on how skilled the planner is). If you have individual requirements or particular property conditions, you will need a custom design.

We didn’t have a standard new development plot, but one with a very unusual shape, so it quickly became clear that a standard house from any manufacturer would not be suitable. We chose to work with an architect.

From your description, it’s hard to assess how special or unique your plot and building requirements are, or whether there might be a standard house that would fit.

Hello @Leon282,

we are currently building a custom-designed house (boundary development) with QNG certification and KFW300 standard. Our price is €3,300 per square meter (without earthwork, foundation slab, carport, garden, photovoltaic system), which is roughly comparable to your offer. I consider this to be market-appropriate at the moment.

If your consultant says QNG cannot be achieved with a windowless facade, that is a simplified statement. The correct requirement is that you need to demonstrate a certain daylight factor for your living spaces (!). On the windowless side, you may then have to use skylights and/or plan storage rooms, bathrooms, or utility rooms there.

Owner-provided work and QNG certification are not mutually exclusive in principle. We outsourced the trades for electrical work, heating, and painting. However, I can well imagine that your provider excludes this because they would no longer have control over the trades and therefore might not be able or willing to guarantee a certain quality of workmanship.

After that, he put the QNQ Line catalog aside and said we could forget about it.
What I also found strange was that this was the initial meeting, and he said we had to sign by the end of April, otherwise prices would increase from May 1st.

Well, that's the typical house salesperson for you. The main thing is to get a signature.

A wall without windows is beyond his imagination, even though from an energy perspective, a wall without windows is better than many windows. But his catalog doesn’t allow for that, so he’s overwhelmed.

If you like glossy brochures, show homes, salespeople with freshly shaved scents, you’ll end up paying high prices because the whole operation has to be covered. Also, for those who are just looking for inspiration and collecting catalogs.

It’s better to look for a smaller builder, maybe even one who only builds a few houses a year. They tend to be more flexible and usually have better expertise. Especially for things like KfW/QNG standards, where it gets quite technical. There are general contractors who do this and can handle it well. And most importantly, they can customize. They don’t have glossy brochures or high-tech websites—they are doers. Then you check a construction site, or some photos, and you’ll see how things really are.

The providers currently offering crazy discounts wouldn’t even be considered anyway...
