Let’s make a conservative rough estimate without much fuss:

House cost: €2,500 x 155 sqm (1670 sqft) = €387,500
Basement: €80,000
Additional construction costs: €50,000 (If the house is from a general contractor or self-built? If from a contractor, several €10,000 in property transfer tax may apply).
Initial outdoor facilities: €25,000
Garage (if not included in the 155 sqm): minimum €25,000
Total: €567,500

Hello Acof,

You are right that the total amount was stated somewhat carelessly.

Upon further consideration, I realized that I incorrectly specified the living area because the stairwell area was included. It measures 5.94 sqm (64 sqft) per floor. This means the actual living area is about 143 sqm (1,539 sqft). Unfortunately, the first post cannot be edited.

Furthermore, the value of self-performed work has not yet been taken into account, which I estimate as follows. I would appreciate any feedback.

[Bold]Explanation:[/Bold]
- We plan to do the painting and flooring (final finishing) ourselves.
- As an electronics technician specializing in energy and building systems, I will only need the materials; the other work will be done by myself at no charge besides my hourly rate.
- For the garage and landscaping, we also plan to contribute a lot ourselves and, if possible, avoid paying for craftsmen’s labor costs up to 90% (except for the garage roof truss).
The savings from self-performance were researched online from various sources.

So far, I’ve found figures on the internet with costs up to €2,200 per sqm (204 sqft). Is that unrealistic?
This results, when considering €2,200 per sqm total costs, in:

I would be really grateful for any feedback or corrections.

Best regards

Sascha

Hello Haydee,

thank you very much for your feedback.

Is the budget including additional construction costs?
I already tried to explain the budget in more detail earlier, see post https://www.hausbau-forum.de/threads/einfamilienhaus-in-l-form-mit-ca-155qm.39680/#post-507657. If you have any suggestions or spot errors, please make sure to point them out again.

Are the parking spaces allowed according to the development plan or regulations?
So far, I haven’t found anything to the contrary in the building plans. What does this usually look like?

Try drawing all the furniture to scale.
I need to provide a more detailed version within the next few days. However, with our current furniture dimensions plus some buffer, everything fits well in the house so far.

A walk-in closet and a bedroom with a long, narrow shape take up a lot of space.
Yes, that’s true – that was my partner’s wish. It’s hard to say no to. Reducing the space by the size of the walk-in closet wouldn’t really help much, because the room layout and overall house design wouldn’t work otherwise.

The cloakroom is missing.
The cloakroom is simply not separately marked but could be placed in several spots on the ground floor. It is highlighted in green.

Please upload the pictures directly… (it’s quite tedious this way…)
