Feasibility Single-family house - Cost statement / Financing realistic?

Did not want to start a general discussion on the topic of cellar vs. slab. Current planning on my part does not include a cellar, but a garage with a 2x6m storage room, that should be sufficient

If you choose the right general contractor, plan carefully, then this nonsense about "additional costs afterwards" is not true. Now everyone can tell me: "just start building first" --> Fact is: it won't be like that :D

Do you really believe that?

Then ultimately every basement would have to be more expensive than planned? The OP can't calculate that way anyway :D

It is like that too. Let yourself be surprised. If it's not the basement itself, it's the ancillary costs. Just for excavation including disposal, we had three times the planned costs.

But I love our basement. :)

one little note about the wedding that just 'comes up' in the next two years: If our incompetent politics allow proper celebrations again by then: That costs a lot of cash. 20k will be blown quickly.

Do you really believe that?

It’s true. Let yourself be surprised. If it’s not the basement itself, it’s the additional costs. Just for excavation including disposal, we had three times the planned costs.

But I love our basement. :)

Yes, I really believe that.

Then it must certainly be because you didn’t plan and compare properly?

If I budget 34,000€ for my excavation, since I obtained several offers and know what to expect based on the soil report, I highly doubt the amount will be higher. The offers we have range from 26,000€ to 30,000€. I know exactly how many m³ need to be transported and the maximum amount that can be transported. I take the disposal costs/landfill fees from the offer as well as from the landfill. If I plan a proper buffer for every trade or in the additional costs that "could" be more expensive, then my house will only become slightly more expensive in the end, right?

I am quite sure that most builders calculate very cautiously and also approach things naively, not considering many aspects that later arise. Certainly, that will also be the case for us in some areas – however, I will definitely not leave huge sums of money unpaid for the basement or excavation – quite the opposite :)

Sure, if builders budget 10,000€ for their excavation because Google says so, then they shouldn’t be surprised later if significant additional costs arise.

But yes, I will let myself be surprised – I will report back, in 3 weeks it will be time :)

Yes, I really believe that.

Then it is certainly because you did not plan and compare properly?

If I budget €34,000 for my earthworks, since I obtained several quotes and know what to expect based on the soil report, I strongly doubt the amount will be higher. The quotes for us range between €26,000-30,000. If I properly budget a buffer for each trade or for ancillary costs that "could" be more expensive, then my house will ultimately only be marginally more expensive?

Of course, if builders budget €10,000 for their earthworks just because Google says so, then they shouldn’t be surprised afterwards if significant additional costs arise.

But yes, I’ll let myself be surprised – I will report back, in 3 weeks it will be time :)

1. things turn out differently and 2. than you think. I am looking forward to your report.

But how can a basement cost 65k when the excavation alone is 30k? So for us, the basement cost 60k more than the same house with a slab. Then we had earthwork costs amounting to 23k, which otherwise might have been only 5k. So the basement has already cost 80k more than the house with a slab.
