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)

There is also a technical reason to avoid it. For walk-in showers, the screed must be installed with a slope. This often means the minimum coverage over the heating pipes, usually 45mm (1.8 inches), is no longer met.
I have it in my own house; the screed had to be done on site because of this. Whether the minimum coverage was maintained, I don’t know and I don’t really care.

In our case, this is handled by the tiler who works with the general contractor. A master of his craft and a one-man show :-)

yep, my request for underfloor heating in the shower was unfortunately rejected with the same argument back then.
Which of course is nonsense.
You simply leave out one layer, or about 3-4cm (1¼-1½ inches) of expanded polystyrene insulation in this area.
And then you won’t have cold feet when you step into the shower.

There may be solutions for that. I think they used some kind of “pre-formed slope” or something similar. It was a huge plumbing company, and you either follow their system or you don’t. They were about as flexible as a crowbar...

I also experienced problems with the division of trades and the subsequent warranty.

Underfloor heating: heating engineer
Screed: screed installer
Shower including slope and screed underneath: tiler

The general contractor completely resisted this, as the boundaries were no longer clearly traceable.

The general contractor completely refused because the boundaries were no longer clearly identifiable.

Didn’t they all come from the general contractor? And yes, it’s the same for us. The connection (screed) to the front door is also done by the tiler, since the front door was delivered late.

Positive news from the Bosch representative. The mechanical ventilation system will be installed in 1.5 weeks. The ground source heat pump is scheduled for the end of August. At least we have a date. Hopefully, we can move in by the end of September. We’ll see.
