Is the price for a single-family house in Berlin / Brandenburg possible?

Is the buffer actually a buffer? Because you also have to think about the garage (is it still easier standard when building with a garage?), but at least about the outdoor facilities including the parking space.

Maybe it is also an option to buy the property now and build in a few years only when a larger part of the property is already paid off?

We currently live in a 108m2 bungalow without a basement (rented)

Hello,

We have unexpectedly discovered a plot of land in the Berlin suburbs that we like. As everywhere, it is of course not cheap. We then had 350,000 EUR left for the house, ancillary construction costs, and buffer. Can you build a 120-130m2 single-family house (simple standard, no basement, flat plot) for that?

I found the following:
House: 2000€/m2 -> 240,000
Ancillary construction costs: 15-20% of the house price: 50,000
Buffer approx. 10% of the total project: 60,000
Total 350,000

We received similar figures from a solid house provider: 230,000 for the house, 70,000 ancillary construction costs....

A follow-up financing would be easily possible in an emergency (private loan from a family member), but we don't actually want to borrow more money.

So can you still build a house with this budget? Or better leave it? Building plots go quickly here, so we should decide quickly.

Thank you.

... you can see if a bungalow is possible.
For a bungalow with 120 m2 of living space, floor areas of 150-160 m2 are required with actual wall thicknesses.
And these plots are rarely found

And it takes a while until the land is paid off, it costs almost as much as the house
