Does anyone know a cheap (prefabricated) basement provider?

Now we have realized that our future property - if we build with a basement - which will probably be necessary due to the 4m slope - will likely have to be ordered with a white tank because of water running down from the slope and the street.

Additional cost €20k on top of the basement price of €50k = €70k total madness. (220 sqm house), basement with ceiling height increased to 2.55m as well as seals, heating, electricity, etc.

Does anyone have a tip for someone who builds affordable basements?

Hello fire00,

especially with the basement, as the foundation of the whole building, I would be very cautious when it comes to "cheap" providers.

We have had very good experiences with Glatthaar-Fertigkeller. They are certainly not the cheapest, but quality, punctuality, and service (we had a small complaint) definitely speak for themselves.

Regards,

Dirk
