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)

Of course, I can only speak from my own experience and wouldn’t tell others in a forum to do this or that. Everyone has different ideas and needs, but you don’t necessarily have to repeat other people’s mistakes.
If it costs 4000,- I would think carefully several times about whether it’s worth it to me. At the current rate, I believe it’s 1.49 per 1000 liters (264 gallons), so you can water for a very long time to reach that amount. My brother has a property similar to yours and is an expert at irrigation. He waters 1000 liters (264 gallons) in the garden every day during summer. With that usage, assuming he does it about half the year and using a garden water meter, he could water for roughly 14 years.
I can see it with the 6m³ (6,000 liters or 1,585 gallons) we have now, which we haven’t even started using this year because it has been raining continuously. I hope the next few years will be better, but you also have to expect times like this. For me, spending that money on underground installations would be too much.

One more question about the caseworker in Teltow – was she the caseworker handling your building permit / planning permission application, or the one responsible for planning law? We’ve already had trouble with the latter in advance because we can’t submit an application if fundamental issues aren’t clarified. Do you know her name, the one who caused you so much trouble?

The managing director called and confirmed the drainage system. He will take a closer look at the property over the weekend and then give me an update on this.

The planned construction work for next week will most likely be delayed, as was already expected. We were pleased with the current construction schedule but didn’t really believe the house handover would happen by the end of May, especially not under the current circumstances. We’ll see. The good thing is that we are not under any time or financial pressure, and the availability fees only start in September 2022.

The one who caused us trouble was Ms. D. We didn’t have much involvement with planning law since there is no development plan for the area. Only a few requirements had to be followed. Everything was delayed for a very long time because she was first sick, then on vacation. During that time, the application obviously stalled. What I hate most is when someone promises me an appointment but doesn’t keep it. At least a callback to say it will take another 2-3 weeks should be standard. But that’s just how the building department is. I get the feeling it really works like in the Baumann and Clausen scenario. A friend had just as much “fun” with her. He even showed up in person and broke down crying out of nerves because the delays were costing them a lot of money...

Thank you for the quick responses. Is the 4800€ kind of a deposit that you ideally get back?
Since Borkwalde is not our first house, I can share our experiences with our cistern from our two houses.
We once had a house in Stahnsdorf on about 700 sqm (7,535 sq ft) with around 240 sqm (2,583 sq ft) of roof area. During extreme weather events, our downspouts turned into little fountains, even under the ground. We then retrofitted soakaway baskets and had no more issues. The tank would fill up quickly. But once it’s full, where does the water go? Soakaway baskets again, which aren’t cheap either. Not to mention the pine needles — the downspouts must have screens, or else all the needles end up in the tank. The needles get so compressed that I sometimes had to use pliers to clear the pipes, always in the rain or bad weather. Now we rent a place with a 6 m³ (210 ft³) underground tank. When we connect a submersible pump from the landlord, only a tiny stream comes out. I wouldn’t try to water a large property with that. There are definitely better solutions, like having a pump in the tank that can provide proper pressure. Personally, I wouldn’t know what to do with 10 m³ (350 ft³) of water. I’m a fan of automatic irrigation, and you already need about 2,000 liters per hour (530 gallons) pump capacity to water larger areas effectively. I’d also have to combine that with mains water because the tank will likely run dry in summer. For me, it would be too much effort. Installing the chambers can be done by hand since they settle over time, but by the fourth ring, the earth has to be refilled on top, and the feeling of soil pressing down isn’t for everyone. So you need technical equipment, which of course costs money. If something happens to the cistern over time or you simply stop using it and want it removed, then in a few years an excavator will come through your finished garden. I know how my wife would feel about that. The top ring would have to be removed, then at least 10 m³ (350 ft³) of soil backfilled, and the rest left underground. Knowing my luck, I’ll want to install something exactly where the remaining rings are in the soil. If I still decide to have water in the garden, I would choose the front yard. We are planning about 15 m (50 ft) from the street, which is enough space. When the cistern is full, you can water for longer than three days. You wouldn’t pour 3,000 liters (790 gallons) into the garden in one evening.

Then do the math. If your pump delivers 2,000 liters per hour (530 gallons per hour), it can run for 1.5 hours to distribute 3,000 liters (790 gallons). That’s not enough for 750 sqm (8,073 sq ft) of greenery on hot summer days if you want to keep it lush.

Could someone please briefly and clearly explain to me what a drainage system is and what it does?
