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)

Hello,

So, in our case, the overflow from the cistern is connected to a soakaway. It is buried about 3 meters (10 feet) away from the cistern underground. It works perfectly. So far, nothing has flowed back or come out of the waste pipe filters. Later on, the overflow can be connected to the city’s stormwater drainage system. Unfortunately, it is not yet available in our street. 🙄

Here is the current construction plan. Work will start on November 22. The guaranteed construction period is 10 months. Corona is excluded as an extraordinary event that would extend the construction time.

Thank you for the explanation. There are no pine trees nearby. What do you do in case of larger amounts of water? Is there an extension or connection of two systems to protect against heavy water volumes?

And one more question. What does something like this approximately cost?
I solved something similar above the drainage, as I mentioned. As a test, I let 75m³ (about 2,650 cubic feet) of water flow in over 10 hours. It worked without any problems. However, it depends on the soil; at depths of 50cm (20 inches) and below, we have sand and gravel. The cost is maybe around 300–400€ including a concrete shaft if you install it yourself.

I would have it done professionally. Since they are already digging for the ring trench collectors, the costs are eliminated. So it shouldn’t be very expensive. Thanks again to everyone for the suggestion. I think if it’s feasible, it will be implemented.
