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)

According to the building energy act, everything may be installed correctly, but I can't assess the details. However, there are better options than just the standard.
We have 130 mm (5 inches) of insulation under the screed, consisting of 2 layers of 50 mm (2 inches) insulation with a thermal conductivity of 0.032 W/mK and a 30 mm (1 inch) fixing mat. First, a complete insulation layer of 50 mm (2 inches) was installed, then the plumbing and heating installations were laid on top. The second insulation layer was installed crosswise. This means all hot water pipes are surrounded by the pipe insulation (single layer) plus at least 50 mm (2 inches) of insulation layers around them. This is the floor construction. According to the external site supervision (2 people with a total of more than 60 years of experience), everything is excellent.

This is the floor structure. According to the external construction supervision (2 people with a combined experience of over 60 years), everything is perfectly fine.I can only repeat myself. Surely, everything will be done correctly. But actually, it can be done significantly better with simple means. Can you please already provide some information about the underfloor heating? Has a room-by-room heating load calculation been carried out? What are the spacing intervals for the underfloor heating? What is the capacity of your heat pump?

Could you please already share some details about the underfloor heating? Has a room-by-room heat load calculation been done? What are the pipe spacing for the underfloor heating? What capacity does your heat pump have? Here are the details from the construction specifications regarding the installation and the heat pump. It will be the Bosch model: Bosch Compress i7800 LWM.

After your response, you will receive a standard underfloor heating system. Why? Because you did not answer a single question from my last inquiry. You are relying on 60 years of professional experience.N

Because you didn’t answer any of the questions from my last post. You should trust 60 years of professional experience. Have you already read the attachments? They include the pipe spacing, mention that there will be a heating load calculation and hydraulic balancing.
We’ve also discussed this topic many times in the forum. I’ve actually been here for several years 😎
Furthermore, the company’s managing director is actively involved in development and teaching about heat pumps at universities. No, I don’t only know this because he told me. On this subject, I trust him.

I have not seen a heating load calculation. There were only two excerpts from the scope of work specifications.
