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

Hi,
That depends on the mason’s fingers.
The gap only serves to give the mason room for his fingers when placing the facing brick between the insulation and the block.
Hence the name "Bratkartoffel"... 🙂

Matthias18216 Jul 2012 12:33Hello everyone,
while comparing offers, I came across a few other differences regarding the walls.
One offer includes all interior walls made of 17.5 cm (7 inches) aerated concrete. Exterior walls are at least 24 cm (9.5 inches), depending on structural requirements.
The other provider offers interior walls with 10.5 cm (4 inches) Poroton bricks and exterior walls with 17.5 cm (7 inches) Poroton bricks, again depending on structural requirements.
Now I wonder, is thicker always better in this case? I actually like Poroton as a building material, especially since I read that aerated concrete tends to absorb a lot of moisture. From everything I have read, it also seems somewhat a matter of personal preference in the end.
I am particularly interested in how the sound insulation properties of these two types of walls compare. The mounting of heavy cabinets or similar items appears to be similarly challenging with both materials.
Best regards,
Matthias

How do you climb the stairs? Do you jump onto the first step?
Is there natural light (windows) in the upper floor hallway?
Two children? Who gets the smaller room?
Is the living room really facing north?
These are just some points that stand out to me as a layperson after a one-minute look.

I would say the exterior view of the gable walls on the kitchen side still looks quite unimpressive at the moment.
If you can’t move the door in the kitchen, maybe you could shift the two windows upstairs slightly outward so that the doors and windows are aligned vertically?
Regarding the lighting in the upstairs hallway, it’s certainly planned that light will come up from below the staircase.
Additionally, a skylight could be an option, but one above the stairs would be difficult to clean.
Your wife might curse you 🙂
I think motion sensors or a few nice LEDs along the stairs would be cheaper than an extra skylight, and you wouldn’t have any trouble with your wife.
Alternatively, you could ask a building expert... I believe she recently revised a floor plan where she included a round skylight or a light dome in a sloped roof section.
Is a chimney still planned? I find those particularly difficult to accommodate in our house. Usually, it comes out in the upstairs area where there’s nothing or right where you want to place a wardrobe.
What is the knee wall height and what is the roof pitch? Have you planned for the fact that you won’t have the full floor area available upstairs?
