Assessment of Additional Construction Costs - Have I considered everything?

Then it is equity, not own contribution

Yeah, I described that wrong.

For comparison, with us:
- Building permit 50€
- Surveying: 3000€ planned (not done yet)
- Soil report: 1000€
- Structural engineer check: 0€
- Inspection shaft: 0€
- Construction insurances: 0€
(Builder’s liability, shell and construction work all free...)

But better generous with buffer.
We have already had extra, for example:
- Additional mobile crane due to cramped conditions
- Pumping out the construction pit
- House connections: forgot fiber optic
- Underestimated construction toilet
And a few more small things.
Not a catastrophe yet, but it’s getting more expensive on its own…

The construction toilet is included during the construction period. Since I’m planning without a basement, fortunately I don’t have to expect pumping out the construction pit.
I have now calculated the mobile crane spot at about 2,000€.

Regarding your administrative costs quantified as 4,000€ as explained above:

Let me back up the things I mentioned with numbers:

- Building permit --> 2,000€
- Surveying --> 2,500€
- Soil report --> 2,000€
- Structural engineer check --> 3,000€
- We have to set the inspection shaft ourselves, for example - it is specified in the development plan - you might also want to check that if you haven’t thought of it yet - costs 2,500€
- Construction insurances --> 1,000€

That would be all in all 13,000€ ---> So be very careful here!

I also initially included the soil report at 2,000€.
I’m not sure about the structural engineer check, since the developer sells most of it as a package, in my opinion the structural check is included. I couldn’t find anything else in the construction and service description.
In my view, an inspection shaft is already present on the property.

Plan at least 50k extra for unplanned costs.

I’m slowly getting there.

Solar collectors are not photovoltaic (photovoltaics) but produce hot water (high-temperature technology) It does not work optimally with a heat pump (low-temperature technology) but it is possible ... Photovoltaics are not subsidized by the BAFA (but rather supported by the feed-in tariff, the benefit lies in high self-consumption). However, there is 200€ per kWh battery capacity (KfW40+). Photovoltaics should also be calculated at net price because changing to the KUR (small business regulation) usually only pays off after 5 years. So VAT again ... Charging infrastructure is subsidized. Currently in NRW better than the subsidy coming from the federal government in November with a flat 900 euro for wall boxes (which, however, must also cost at least 900€ but usually do)

hmm.. then I was a bit mistaken there. I think I got a little confused, for KFW40+ the system is required after all. Unfortunately, I can only calculate and request this later when the floor plan is in front of me. Currently, I have about 20,000€ planned for the great system. In addition, the system should support the air/heat pump with electricity and heat the hot water with surplus energy (maybe heating rod). The system should also supply the devices during the day (washing machine, TV, lights, etc.). Of course, I gladly take the 200€ per kWh battery capacity.

So langsam komme ich daran

So, as I read it, you do have some gaps, but elsewhere quite a bit of buffer. It will all work out. Let us be part of it! Is there still anything to be done on the floor plan?

Is there still room to work on the floor plan?

Yes, I can still do quite a bit on the floor plan, as long as it doesn't become an octagon or something similar, I have free rein. Choosing the city villa doesn't leave much room for maneuver with 110m².
I am curious how the planning meeting will go once I have signed,

- Surveying --> 2,500€

In NRW that would be far too little. If you need an official site plan, you’re looking at around 5,300 euros. If you’re lucky and the unofficial one is enough, you’re just under 4,000.

I don’t know where you’re from. But it makes sense to at least specify the federal state. Otherwise, you often gropingly feel around when it comes to funding.

You already wrote something about the 30,000 equity/contribution in kind. But it’s not just about the terminology. You are not allowed to deduct that amount in the cost breakdown. If you want to make a statement for the necessary financing, deduct the equity from the soft incidental costs that have no added value for the bank. (Broker, fees, taxes, notary)

I'm not entirely sure if our numbers are correct, but we have been given a binding cost from the surveyor of almost exactly 2400 euros in total for the string scaffold as well as the survey after the construction is completed. We are building in NRW. Therefore, I think the 2500 should be correct. Or have I overlooked something?
