Financial requirements for building a prefabricated house

Hello dear forum

Since I, as I realized thanks to you, quite naively approached the house building project, I did some research, read some things here and on the internet, and made myself an example cost calculation. I am aware that in reality it can become more expensive due to unforeseen cases.

The following fictitious plot is given:

350 sqm, fully developed, no soil contamination (determined by soil survey) purchase price €70,000

Capital requirement calculation for the plot see attachment

On top of that, I would build a prefabricated house (120 sqm, purchase price turnkey from the upper edge of the basement ceiling)

€135,000 purchase price prefabricated house + €27,000 (20%) buffer for surcharges, unexpected things, etc. (only related to the house, the plot has its own buffer)

I would finance the furnishing of the house with equity.

Is that correct so far or did I forget something?

Thanks in advance for the answer and have a nice Friday to everyone who, like me, also has to work today (NRW had yesterday off)

Good morning,

just the costs for the land and the house are not enough.
Think of the ancillary construction costs, the basement, carport/garage, earthworks, insurances, etc.

There are already some great cost overviews in the forum from which you can see all of this.

135,000 EUR for a turnkey prefabricated house does not seem quite realistic to me at first glance (too low).
With many providers, the wall and floor coverings are not yet included in turnkey houses; this must also be taken into account!

Best regards

Hi

In the PDF (which I attached) the ancillary costs for the property are itemized. No basement, only slab. I (initially) don’t place any value on a garage or carport. The 20% buffer is intended, among other things, for wallpaper and floor coverings.

I have added earthworks (2,500) to the list as well

Hello

even the 135 purely for the prefabricated house seems too low to me.... you keep working on your dream :) respect!

Hello

even the 135 alone for the prefab house seems too low to me.... you are still working on your dream :) Respect!

Thanks :D

The 135,000 + 20% (I even just increased it internally to 25%) would be almost close to 170,000 – depending on the prefab house provider, more or less is included in the house. So you have to roughly estimate until then – I’ve read some construction logs and think that not more than 20% would have been added there either. I have to look at it case by case.

Thanks, I am persistent when I have a dream. Nothing is given to you :D But I don’t want to be unreasonable either, so preparation is key. At the moment it’s purely hypothetical anyway, since I still have to save some equity until next year. Also, I have the option to borrow money cheaply through my employer,

100,000 for just under 2%
20,000 interest-free
additionally 50,000 each via KFW 153 and KFW 124
the rest then at market interest rates
