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)

Thanks for the info – that sounds good. Then you don’t have to worry as much about airtightness, since the membrane will be glued to the plaster on the sides.
So, stud framing with a substructure.
This is beneficial for the ventilation system, wiring, and everything else you don’t want visible, like lighting, etc.

Here is the construction according to the scope of work. Drywall installation will begin in about 2 weeks.

I’m currently at the construction site to take some photos for the architect who will probably handle the overall planning.

Here are a few photos from all sides.

Anhydrite screed was poured today. Tomorrow I will receive the instructions for the construction dryer 😎

Renovation room: open area with wooden beam ceiling, damp floor, and window view to the outside.


Shell corridor with smooth concrete floor; right brick support and unfinished walls.

So much for everything going smoothly :-)

Today I received a call from the construction company. No chemicals were added to the anhydrite by Knauf that would enable fast drying. Therefore, the floor can only be walked on starting tomorrow, and the drying time will be extended by 2 weeks. On the one hand, that’s good because there are fewer chemicals; on the other hand, it’s unfortunate because the drying time is 2 weeks longer. He also apologized for the additional 6cm (2.4 inches) of drywall on the ceiling, as he had not informed the planner. As long as it stays with these two issues, it’s not that bad :-)

I have received one more piece of information. The anhydrite screed is dried using the underfloor heating system. This is done with the help of a heating cartridge.

Then go ahead and activate your photovoltaic system...there is currently no more sun coming down, and this way you could already "save" energy or increase self-consumption. 😎
