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 would place the cistern somewhere it won’t be in the way. Possibly near the construction access road; if this would block future access, I’d install it last. And if it’s 20m (65 feet) away from the drainage, just lay a 1 kg pipe.

It’s also about the slope. We have considered placing the cistern on the left side in front of the house. But the path to the collectors would be too long, and a slope would need to be created. I’m still looking into it. We might think about this once the house is built but the landscaping is not finished yet. However, the quoted price is beyond our planned budget.

A brief update. Yesterday, there was an on-site meeting with the earthworks contractor. Unfortunately, the rainwater cistern was canceled due to delivery times. It would only arrive after he finishes his work, which means the excavator would have to come back again, significantly increasing the costs. Also, the construction access road would need to be extended to the desired location, so we’re talking about a total of around €10,000 (approx. $11,000) for the cistern. Canceled.

Because the house is being built quite far back, the access road will cost about €5,000 (approx. $5,500), including removal. Furthermore, we agreed that the soil will be filled up to road level using screened topsoil. Naturally, there will be a slope leading away from the house. The cost for this is €5,400 (approx. $6,000). Additionally, the soil excavated for the foundation slab will be disposed of. We have initial estimates (which depend on soil quality), but we are still negotiating 😎

Yesterday I also received a quote for the house connections for drinking water, wastewater, and construction water. I budgeted €20,000 (approx. $22,000) for this, including electricity (the house is being built 16m (52 feet) away from the street). The quote for water and wastewater came in at €9,800 (approx. $10,900). That leaves just over €10,000 (approx. $11,100) for electricity.

Can you ask your neighbor about the groundwater level? Depending on that, I would consider drilling a garden well with a 1.5-inch suction pump (about €500 / $550), or a deep well pump with a 5-inch pipe (about €2,000 / $2,200).

I don’t understand why the failure of the civil engineer is now being blamed on you. He knows the current situation and should have clarified the delivery times beforehand. If he missed that, then he should cover the additional costs.


Yes, he should have. But since he still has quite a bit to do on our property, I’d rather bite the bullet. We actually have a good relationship that I don’t want to ruin over something like this. He has already done a few extra services for free and promised some more. So it’s not a big deal...

Can you ask your neighbor how high the groundwater level is? Depending on that, I would drill a garden well with a 1.5" (about 3.8 cm) suction pump (around 500€), or a deep well pump with a 5" (about 12.7 cm) pipe, around 2,000€

For us, it’s about 100 m (330 ft). I had the same idea. But it’s not cost-effective.

Yes, that’s the big problem right now—that you’re dependent and he can dictate everything because of that.

Exactly. By now, I’m used to being dependent on the building authority 😎 And since it’s “just” a rainwater cistern, it’s not ideal but acceptable.
