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)

I find it interesting that the foundation and the slab are two separate parts. And that they are also constructed on different days.

It was the same for me. Apparently, the ground slab is not necessarily a load-bearing structure (don’t ask me how that works).

In any case, I was told at the “shopping center around the corner” that while this is structurally possible, it reveals a very low-cost construction method.

I can’t say much more about it, except that the experts there are quite elitist and tend to favor high-end construction methods (not necessarily in terms of price, but regarding technical standards).

My building inspector did not have any negative comments about it.

For us, it is one piece. Whether this is technically better one way or the other, I’m not sure. I would have thought it is always done this way because it is probably more cost-effective.

The gravel being used here was called fill sand in our area. According to the earthworks contractor, it can be compacted to the required standard and is load-bearing enough for an entire house. For example, trench walls do not collapse.

For our 16 x 10 m (52 x 33 feet) slab, the strip footing and slab were poured in one continuous process, without any steel mesh reinforcement, using fiber-reinforced concrete.

Strip foundation and slab poured in one go,

Was it the same general contractor as well?

For us, they were done separately!

Yes, the same general contractor, and it seems he always does it this way with bungalows.
There are also strip foundations partly under the interior walls.
