Additional costs for a turnkey house of 48% - realistic?

You didn’t mention anything about a semi-detached house in the first post. The construction method and the federal state are also nowhere to be seen. In addition, there are the incidental construction costs (typically between 30,000 and 40,000 euros), details such as the kitchen, garages, and outdoor facilities are naturally also excluded. Do the math, if a provider deviates significantly from the average, extreme caution is advised.

Hello,

Let's stick to the concrete example: the plot is already owned and developed!

House: €109,900
extra insulation: €3,300
solar package: €4,300
ventilation package: €7,500
--------> house costs: €125,000 for a 140sqm house

SH is - to a small extent and similar to Lower Saxony - cheaper than the rest of the country; unless you want to build in Kiel. But not that cheap. A house of this size should cost around €168,000 in SH.

plus:
chimney approx. €4,000
external roller shutters: €5,000
possibly further special equipment €10,000
kitchen: €8,000
house connections: €7,000
fees (building application / construction and soil survey): €5,000
miscellaneous / backup: €10,000
paint / wallpaper: €2,000 (DIY)
floor coverings: €3,000 (DIY)
financing costs: €3,000
additional earthworks: €3,000
construction electricity: €1,000
insurance and co: €200?
additional costs-------> €61,200

The costs for the building application are set too high, material costs for floor coverings and wallpaper too low, and a kitchen does not belong in this list. Regarding the additional foundation costs, I would estimate a good €8,000; otherwise, take a look here:

total effort turnkey without exterior facilities: €186,000

No - a good €177,000 plus €30,000 construction incidental costs, plus €8,000 reserve for additional foundation costs, plus €10,000 for painting and floor coverings as DIY, plus €10,000 for exterior facilities as DIY, plus €8,000 for a prefabricated garage 3 x 6, plus reserves for extras.

2. Did I understand correctly? Would the house be KfW 70?

From experience: no.

Best regards

Hello,

I found a construction diary with the developer on the internet. In 2011, a city villa with 138 sqm was built. The base price was 114,900 euros. In the end, the construction with extras cost about 162,000 euros. Link is available by PM

As a simple house, built according to the energy saving ordinance valid at the time and with EL painting and flooring, this is also a realistic price in SH ... not a KfW 70 efficiency house and without additional construction costs etc. ...

Kind regards

The example with the city villa is a detached house. The price is about 1180 euros per sqm. The city villa now costs 2012 ->124,900 euros, so with additional services at 1246 per sqm. The developer builds about 500 houses per year and is regional. In the meantime, an architect also called me. Her price is 1300 - 1500 euros per sqm - ready to move in including painting and floor coverings. Is building in Schleswig Holstein cheaper?

I would like to post the provider here
