Hello everyone,
We are currently looking for a developer for our house. At the same time, of course, we are also focusing on the right design, features, and price of the house.
Building a house is truly an adventure, and as you can imagine, there are a thousand questions and it’s hard to know where to start.
What I would like to know here is whether we are on the right track with a specific offer and if it can be implemented without any major concerns.
The key details are as follows:
Single-family house with approximately 140m² (1,507 sq ft) of living space, gable roof without dormers, KfW 70 standard, and
- central mechanical ventilation with heat recovery
- triple glazing with a U-value of 0.5
- solar rooftop system for domestic hot water with a 300-liter (79-gallon) storage tank
- roller shutters on the ground floor and upper floor
- underfloor heating return circuits in bathroom and kitchen
- triangular windows in the gable ends
The price for the whole package is supposed to be 180,000 euros. Overall, I find the price fair, but of course I’m also interested in your opinion.
Then I have a few more questions:
1. The construction description has very little information about the ventilation system installation. Should I follow up on this?
2. A condensing boiler from Vaillant, Junkers, Elco, or equivalent will be installed. Is this recommended, or are there specific things I should look out for?
3. What other aspects of the construction description should I pay attention to before accepting the offer? Are there any critical points I should be aware of?
Looking forward to your answers.
Best regards,
Matthias

He is still trying to do it himself and still doesn’t seem willing to seek professional help.
How did you calculate the square meters? The software looks like Sweet Home 3D.
You need to take the knee wall height into account; with a knee wall of 1 meter (3.3 feet), the small children's room won’t have 12 square meters (129 square feet).

Matthias18218 Jul 2012 19:21Yes, it is Sweet Home 3D. I don’t have anything better.
The knee wall would be 1m (3 feet 3 inches) with a 45-degree roof pitch.
Unfortunately, I can’t manage a larger children’s room. Or do you have any suggestions?
The stairwell only gets light from the window at the bottom.
We won’t install a chimney, so I don’t need to worry about that.
I can’t afford a bigger house. I have to make do with what I can get for my money.

Neubau201318 Jul 2012 21:39Hello,
the gap primarily does not serve to protect the bricklayers’ hands. My hands had plenty of scratches even without an air cavity. The purpose of the air cavity, as its name suggests, is to allow air circulation to absorb any moisture that may occur and carry it away from the masonry. This is ensured by ventilation grilles placed above the vapor barrier foil, under the window sills (roll layers), and above window arches on the mini vapor barrier foil.
Also important, although not intended by the builder, is that cavity wall ties (wall tie anchors) are difficult to bend without an air cavity. Anyone who has often built Dutch bricks without the proper weight or steel-hard fired facing bricks without an air cavity knows that the air cavity is invaluable, as it allows you to bend the wall ties properly without shifting the bricks.
The air cavity is also useful for forgotten cables or empty conduits.
By the way, my house has an air cavity of 3 to 3.5cm (1.2 to 1.4 inches).
I hope I was able to help a bit!

Hello,
Yes, but the question wasn’t about the air gap itself, it was about the finger gap that inevitably forms when installing cavity insulation. And there is no air circulation there.
What use is an air gap if it’s packed full of stuff?
Nothing belongs in the air gap except air, as the name clearly implies 🙂
Best regards

We are currently building a single-family home ourselves and have visited several builders in our area. We have spoken with various tradespeople, civil engineers, and others, and I can only give you one piece of advice: build with a partner who works exclusively with tradespeople from your region and check with their partners to ensure everything runs smoothly. That’s what we did, and it has worked out great so far. The crucial tip came from the civil engineering company. They know each other well. I don’t believe you can judge the quality of an offer based on the branded products used. Unfortunately, we experienced that those who advertise with brand-name products often end up working exclusively with tradespeople who definitely do not come from our area—in fact, the opposite. From my perspective, regional tradespeople are about 5-10% more expensive, but for us, it has absolutely been worth it. The planning phase went smoothly, and the shell construction is currently proceeding without any problems.
