Then I would also like to introduce our building project here and keep you updated.
First, a brief introduction about us. He (42.5 years; controller in healthcare), she (38.5 years; full-time teacher), child (8.75 years; fully dependent). Our household net income is currently about €6,400 (approximately $6,800) plus performance bonuses, 13th-month salary, overtime, etc. We own a 1,462 sqm (15,735 sq ft) plot of land in Fichtenwalde. The remaining debt on the land is €37,000 (about $39,000). According to official land value guidelines, the land is valued at €146,200 (about $156,000) (€100 / sqm). The market price is around €400,000 to €600,000 (recent sale prices). We submitted the building permit application including the land conversion at the end of December. We expect approval by mid to late July.
The construction company is KB Brandis from Jüterbog. External site supervision will be handled by Bauherrenhilfe with 13 appointments.
Now about the house. It will be a 144 sqm (1,550 sq ft) bungalow plus a 12 sqm (130 sq ft) covered terrace with the following additions:
- Ceiling height 3.00 m (9.8 ft)
- Electric roller shutters (including smart home integration)
- Double-sided laminated windows (wood-colored; RC3 security rating)
- Brine-to-water heat pump with ground collectors due to water protection area (Bosch Compress 7800i LW)
- Hydraulic balancing of the underfloor heating
- Controlled residential ventilation with heat recovery (Bosch)
- Motion detectors from a security company
- 13 kWp photovoltaic system, including battery preparation
- 10 m³ (2,650 gal) cistern for rainwater use
- Doorbell with video function
- Wallbox preparation for electric vehicle charging
- Exterior lighting
Floor plan attached.
We have not yet finalized financing (although discussions have taken place). So far, we have invested up to €30,000 (approximately $32,000) from our own savings during the planning phase. This is almost all of our equity. However, we continue to save about €2,750 (approximately $2,920) per month. The monthly mortgage payment is expected to be around €1,650 (about $1,750) plus additional costs of approximately €200-250 (about $210-265) (taking into account the photovoltaic system). This means when we move into the house, we will still have savings of at least €1,500 (about $1,590) per month.
The construction contract will be signed within the next few weeks. The prices (recently discussed with the company) correspond to the offer and commitment as of September 2020.
The price per square meter of the house (according to the latest offer and full specification) will be €2,700 (about $2,870). This includes everything, such as painting, flooring, etc. The overall costs are structured as follows:
House: €378,000 (about $402,000)
Land conversion including reclassification: €25,000 (about $26,600)
Additional building costs: €40,000 (about $42,500)
Outdoor facilities: €25,000 (about $26,600)
Total financing volume: €468,000 (about $498,000)

13 heating circuits for 144 sqm (1550 sq ft)? I think that’s too few. We have 13 heating circuits for 90 sqm (970 sq ft). Pay attention to the pipe diameter from the heat pump to the manifold. Make sure there are no bottlenecks here and that the pipe diameter is sufficient.
According to some experts, lowering the flow temperature (VLT) by 1 degree results in an efficiency increase of 2.5%. So reducing the VLT from 35°C (95°F) to 31°C (88°F) means a 10% efficiency improvement. Even an 8% improvement would already be a good result.
You mentioned the screed will be installed soon. So the underfloor heating must be installed beforehand. For this, the heating engineer needs the heat load calculation to properly install the underfloor heating! Keep in mind that any mistakes in the underfloor heating design will remain in the house permanently. You can always replace your heat pump, but not your underfloor heating.
For the design, we chose 22°C (72°F) in the bathroom and 21°C (70°F) in the other rooms. The pipe spacing everywhere is 11 cm (4.3 inches), and 5.5 cm (2.2 inches) in the bathroom, including under the shower and bathtub.
How much output does your heat pump provide? From my perspective (assuming a correct calculation), 5, maximum 6 kW should be sufficient. The pump data is below. It’s from the heat pump brochure and available to everyone :-)
As mentioned before, I know that the managing director places great importance on heat pumps and their installation (it’s his passion), so I rely completely on that.

I would definitely prefer the 144 m² (1,550 sq ft) over a 3-room apartment as a bungalow.
By the way: his place is basically finished, so there’s no need to bring up possible or further optimizations.
Next thing you know, someone will ask why not KfW 40, then KfW 40+, then Passive House…. If he doesn’t like my suggestions, he can tell me himself, right? Or are you his guardian?
Why only 90 m² (970 sq ft)? Being over 60, we still wanted to pay in cash and avoid taking out a loan. Also, our hobby is traveling with a motorhome, which we do without financing, by the way. We have a plot with direct water access, and according to the development plan, we are allowed to build a jetty. A boat might be possible. You see, everyone has different ideas about life. By the way, we once had a house with 220 m² (2,370 sq ft), it was nice with the kids living at home, but at our age, never that big again.

However, I also expect some understanding if I don’t implement everything. It’s not because I’m selfish or stubborn, but some things can’t be done anymore, or I have to rely on the building company. I’m already asking/bothering them enough 😎

It’s not due to stubbornness or egoism, but because some things can no longer be changed or I have to rely on the construction company. I’m already asking/bugging enough 😎This approach is very understandable. That’s how I have perceived you so far.

Wood-look tiles (@11ant’s favorite covering) I should probably clarify that I have no technical objections to this; it’s just that the idea of such "transgenic building materials" inevitably makes me laugh. To me, this kind of invention seems as much of a novelty as vegan meat (I’m totally fine with meals made solely from vegetables – but if I want to eat meatless, I simply skip it, not just virtually). I’m just "waiting" for someone to apply this decoration technique to "leopard print," and considering "rusty" painted cars, bathroom tiles with lime stains would, of course, be possible too ;-)

Of course, you could also make bathroom tiles with lime stains.You should get a patent on that right away and register the trademark "Guaranteed Easy Care."
