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)

Neubau202214 May 2022 22:23I have now ordered the Fritzbox 7590 AX. Along with it, a Bosch Professional Laser Distance Meter GLM 40.
My wife said that with the new house, we will probably need a few more tools. I didn’t need to be asked twice.

Does this mean that the pipe layout determines the supply temperature? Once the layout is done, nothing more can be adjusted during the settings? I still don’t understand the relationship between supply temperature, pipe layout of the underfloor heating, and heat pump settings.Of course, the pipe layout sets the supply temperature – along with your insulation standard and transmission heat loss. It doesn’t get any better than that.You adjust everything else with the heat pump. Your HVAC technician did a very neat job visually – respect! Ask him, when the time comes, how to set the heat pump so that all heating circuits are open and the ERR function is inactive. That would be the most efficient setup.
When will your ceiling be insulated? If it had been done before the interior plaster, the vapor barrier foil could have been integrated into the gypsum plaster. Or will the ceiling still be suspended with a subframe?
I would pay extra attention to airtightness there. Otherwise, everything looks great.

The rest is set using your heat pump. Your heating technician did a very neat job visually! Respect!

When will your ceiling be insulated? If it had been done before the interior plaster, the vapor barrier film could have been integrated right into the gypsum.
Or will the ceiling be suspended with a substructure?

@Neubau2022 The ceiling will be finished with drywall. An 11cm (4.3 inch) thick drywall layer, with the panels laid on top. The external building supervisor mentioned that ventilation needs to be considered. The attic was not finished beforehand to avoid mold formation (that was the information given).
The attic is intended only for storage; no rooms will be created there.

The attic is intended for storage only; no rooms will be created there. Thanks for the information – that sounds good. Then you’ll also have less to worry about regarding airtightness, as the vapor barrier will be adhered to the plaster on the sides.
So, a stud frame with a substructure.
This setup is good for ventilation systems, wiring, and everything else you want to keep hidden for lighting, etc.
