Hello dear forum

we want to build a single-family house on our plot in Bavaria (86***) and have contacted a local house building company that offers turnkey wooden houses (including floors and painting work). We want to delegate as much of the organization as possible and not contribute any own work because we neither have the time nor the craftsmanship skills. Additionally, we currently live 2.5 hours by car away from the construction site.

The key data are:

    [*]Plot: 740 sqm with development plan (already purchased, developed up to plot boundary, soil report will still be done)
    [*]Living area: approx. 170 sqm
    [*]Gable roof
    [*]With basement
    [*]Large single garage (approx. 30 - 35 sqm)
    [*]Dormer gable
    [*]KFW 40
    [*]Heating/ventilation LWZ with underfloor heating

We have received the following total cost estimate, which is given with a variance of ±15%.


































































Wooden house (from top edge of basement) €390,000
Basement shell €105,000
Basement finishing (partly living level) €22,000
Additional earth / drainage and masonry work €29,000
Dormer gable €30,000
2 x roof windows €6,000
Interior painting €8,000
Surcharge for floors/tiles (additional buffer in selection) €2,000
Garage + integrated house entrance canopy €30,000
Water supply / disposal €2,000
Electricity connection €1,500
Telephone / cable / TV €2,000
Surveyor costs / soil report €3,500
Outdoor facilities (paving, terrace, fence, parking space) €28,000
Other costs (construction electricity, water, insurance) €3,000
Total (±15%) €662,000


Do you think this is realistic? Should I rather add the 15% (approx. €100,000) to my expectation?

The next step would be a design contract with their architect for which they charge €6,000, which will be credited in case of commission. If we decide not to build the house with them, we will probably get all documents and plans to approach other house building companies with them (no idea how realistic that is...).

Since I bought my first house completely from a developer, this design contract surprised me a bit, is this common practice? Are the €6,000 okay? In the end, you are already committing quite strongly to the company before you have even seen the final fixed price.

Thank you very much for your assessments!

Sebastian

The painting work looks very cheaply planned to me, and the buffer of 2,000€ for [Bemusterung] is simply unrealistic. It is supposed to cover floors, tiles, sanitary, and electrical work. I would definitely plan for a five-figure amount there.

Hello SoL

Thank you very much for the estimation, the €8,000 painting work refers exclusively to the whitewashing. All preparatory work, such as filling, is already included in the "turnkey house". Do you still find it too low then?

Regarding sampling, it probably depends on how satisfied we are with the standard, right? But it certainly makes sense to plan a bit more buffer for extra requests!

Depends on what you have planned. Wallpaper? If yes, what kind? I believe the painting work is calculated per m², so if you have a lot of wall/ceiling area, it will be more expensive than if you have less.



Well, just for a "nicer" bathtub, you can easily spend 600-900 euros. If you don't want anything additional and use the standard equipment everywhere and don't want any extra sockets and...

You understand where I'm coming from...

Yes, that's right! Then I will definitely add something to that. My goal is anyway, as often recommended, to do a preliminary sampling so that the additional costs of sampling are already determined before signing the contract.
