I generally consider Excel tables for this purpose as they tend to create illusions of comparability. I interpret the price equality of the base slabs as an indication that you want to assign these not to house providers A or B, but "on the construction side." The interface OKKD or OKBP is a point of contention with high potential for trouble. In my opinion, the base slab or at least its construction management must definitely be included in the lot "construction contract concerning the house." The supplier’s slender foot is the builder’s wet foot. Don’t weaken your role in this game!

Yes, but they will eventually need to be replaced, possibly in 10 years, so a savings rate of €300/month only covers one car. If you rely on two, that’s about €600 per month.


That’s no problem. But as I said: fixed costs like the demolition should be definitely placed first, then the necessary permits second, so you can see what is fixed (and definitely reduces the budget), in the middle the house costs and the related ones, and lastly the optional items or those you can include if budget remains (garage and outdoor areas).
Anyway (I don’t have to deal with it later), I’ll explicitly ask now:

Are both houses from the same house builder? How come one house costs about one third less? What is missing in terms of equipment in that house? What else comes on top? Those are, by themselves, unrealistic prices.


Yes, exactly because of the construction service description. Every offer should include the BLB as well as the design. Because one house has more, the other less.
You won’t get a turnkey house if you choose a shell house or if the standard is completely stripped down. That definitely means additional costs. You are comparing apples to oranges.
Honestly, I don’t understand why you make such a mystery out of it.

Then:
- what are those architect fees if you take a prefab house and on top have the item change lump sum? What is planned and additionally changed there?
- Why is the snow load statics calculated separately? That should be included in the house package.
- Exterior plaster: I tell you, don’t take the cheap mineral plaster, but the more expensive silicone resin plaster. However, this also depends on the house and location.
- End-side insulation of the foundation slab? Then the base waterproofing is still missing.
- What’s the use of a chimney shaft without a chimney?
- Mechanical ventilation with heat recovery (KWL) would be a must-have for me, because airing out three times a day reduces the lifespan.
- What is a “life cycle analysis”?
- What does the sampling lump sum include? Enough power outlets?
- Construction power/water meter and consumption: duplicated; where on earth does the rent for the construction power box cost nearly €6000 for the build period? You are having a house delivered, right?!
- Chimney sweep acceptance cost us €200, I can’t make sense of the other listed items.
- I know from somewhere that PV (photovoltaics) has nothing to do with the main power box…
- For the permits, I personally miss the overview; there are in my opinion too many lines planned, it just confuses.
- Smoke detectors are mandatory by companies (may be different now).
- Fire protection switches? Whoever needs them puts them in the electrical section.
- What does the notary do here?
- What is a general construction manager?

Overall, I think some house building options got mixed here. Possibly a listing from a builder who built with an architect was altered and filled with additional costs so that many things are duplicated. Some things I simply don’t understand (maybe it’s me), others are missing in my opinion. That’s why I don’t like Excel tables in house construction. The builder loses sight of reality when he takes a wrong turn.
What is missing?
For example, floor coverings, painting work, possible attic conversion (for storage), additional electrical, stairs upgrade, what standard do the walls have? Is wallpaper and paint included? (Danwood includes that, but you have to pay extra for the electrical cabinet at DW), sanitary: what standard is the one shower? Is a walk-in shower planned, which costs a lot extra, what kinds of toilets are planned? Etc. Is the underfloor heating in the bathroom enough? Does a towel dryer still need to be installed? Or do the heating loops need to be closer together? Are the wall coverings in wet rooms sufficient? What security standard is installed on windows/doors? Must transitions to terraces be planned? Are you dreaming of sliding doors to the terrace which might not be included in the BLB? What about outdoor lighting? Outdoor faucet? Outdoor socket? Does a domestic hot water tank still play a role with a heat pump, possibly requiring enlargement?
And if all that is to be found in the €15K and some change, then it belongs in the table too!

It’s no fun giving answers if the original poster doesn’t cooperate. I could still ask 30 more questions if something is included or not.
You will get lost in your Excel table as well as in the deep world of the construction service description, which according to your statement includes everything standard in both offers.

Thank you very much - I will gladly address your points tomorrow. Here is still the BLB. The second provider we have calculated here is Danwood. The difference between building type 1 and 2 is that one of the buildings is the S-line (higher ceilings, larger windows, etc.).

I read the post about your project with interest, as I am currently realizing my own dream. You have put a lot of thought into positions related to construction, but you have forgotten one of the most important ones.

- Insurance
- Construction supervision (TÜV)

Regarding the cost of insurance, I can only tell you that I invested about €2,500 (elemental, legal protection, construction performance, construction liability), but these depend individually on your project and location. For construction supervision, also budget about €15,000 (€1,000 per site visit). You are not professionals and therefore cannot in any way evaluate whether the execution was performed properly.

Furthermore, you should reconsider some or other "wishes" or think about whether these can be realized at a later time. The garden is not that important initially, and a garage or carport (if it is not firmly anchored to the building) can also be built later.
Unfortunately, the breakdown of the building costs does not show what accounts for the price difference. Unlike you, I decided against a prefabricated house and awarded the individual trades separately. This was/is quite an effort, but so far it has saved me easily €100,000 in costs.

A note on your financing: With €2,500 it is possible to finance €650,000 with a high equity ratio. It is best to speak with a nationwide financial advisor. They can best assess your situation and whether you can get a loan.

how about the 700.--€ from the side job? Do you have time for it during the construction phase?, later in your own house? if there are children? Can you pause or will the customer base, built up over many years with great effort, be lost?

Are we talking about a Danwood Park 156W S in one of the offers (and which one in the other)?
