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)

More isn’t always better. Try listing everything that’s supposed to be there individually. You wouldn’t have two dozen radiators, for example. On average, that’s one radiator for every 5.5 m (18 feet) squared.

I will ask the site manager for the installation plan and then answer the question 😎

If each loop is only 50 meters (164 feet) and you calculate with a maximum forward temperature of 30 degrees Celsius (86°F), that is fine. Then, for the bathroom, use a maximum installation spacing of 5-7 cm (2-3 inches) and perhaps a wall heating system. The circulation pump will benefit from this.

I wouldn’t exclude the side-by-side system either; if the settings are different, you can feel a difference of 1-2 degrees Celsius (2-4°F) when walking. I notice it every time I step into the shower.

And I wouldn’t exclude the side-by-side layout; if there’s something different there, you can feel a 1–2 degree (2–4°F) difference when walking. I notice it every time I get into the shower.

I haven’t dragged that yet. I have applied for the installation plan. Once I have it, I’ll list the key points such as heating loops, their lengths, and spacing in each room. Any other relevant points?

Not in my case. Please read carefully 😎
That's right, it wasn’t you after all.
(because here every second new build, house build 1, 22, 55 or whatever is named, it’s hard to keep track... 😀)

I spoke with the specialist earlier. He showed me the installation plan. 26 heating circuits 😎
That’s impressive, with just 12 “separate” rooms.

The company is ATHE-Therm, by the way.
Same as in our case. 😉

You can definitely feel that. But the temperature difference is actually much greater.

That’s quite a statement, with 12 "separate" rooms.

Just like with us. 😉

You can definitely notice it. However, the temperature difference is significantly higher.

Is it working out well with the company? Have you had good experiences with them?
