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)

The drywall installation has been completed. Next week, the tiler will come, and the fireplace will be finished. In the garden, the flat-plate solar collectors are still being installed diligently. The drainage system, as well as the electrical and water connections, are also being set up in the garden.

Construction site in the forest: excavator digging earth mound, shovel in front, trees and greenhouse behind.


Shell niche with green drywall panels on walls and ceiling; uneven floor.


Construction status: green drywall panels, installations for sink at bottom right.

This gap next to the toilet is probably intended as a shelf, right?

There are heating coils from the underfloor heating in the shower, correct? In our case, the entire area was left out—I’m just wondering why.

Yes, that will be an illuminated shelf. Two more will be added: one directly above the bathtub and another inside the shower partition. But the tiler will handle that. As for why they were left out in your case, I don’t know :-)

The reason the specialist installs heating cables in the walk-in shower is so that in smaller bathrooms, the heating system is sufficient to warm the entire room. Often, 7-8 sq m (75-86 sq ft) is not enough, so the shower area is included to make it adequate. However, this is usually the homeowner’s preference and must be communicated accordingly. Because often, in the building scope description or standard house plan, only a shower tray without underfloor heating is planned. If the homeowner opts for an upgrade, everything needs to be carefully considered, including the tiled floor, for example. That’s also why this forum exists—to help with these issues.
@Neubau2022 does not have a low-cost general contractor.

There is also a technical reason to avoid it. For walk-in showers, the screed must be installed with a slope. As a result, the minimum coverage over the heating pipes, usually 45mm (1.8 inches), is often no longer met.

I have this in my own home, and the screed had to be done on site for that reason. Whether the minimum coverage was maintained, I do not know and I do not care.

I have it in my house; the screed had to be installed on-site because of this. Whether the minimum cover was maintained, I don’t know and I don’t really care.
Yep, that argument was also used to reject my request for underfloor heating in the shower back then.
