Construction costs are currently skyrocketing

Aerated concrete or brick? :) Gradually, some trades are dropping in price

Brick, since it is "only" a single-family house.

And how big is the shell including the garage for €135,000?

2 full floors, single garage with 8m length plus a technical room attached at the back with 10sqm, living area: 180sqm, width: 10.11m and length: 14.36m. Slightly unusual shape because our plot is quite narrow but long. Hence also "only" the single garage.

Including foundation slab?

Does anyone know what these small "cordless screwdriver"-like devices for tying rebar are called?

If that includes the floor slab and foundation, then the shell builder must be in quite some trouble and urgently need revenue. Because he doesn't earn much from it. Even if another 150,000 EUR is added for the turnkey construction, it is still under 2,000 EUR/m² including the garage. Not even discounters like Town & Country or Heinz von Heiden can manage that anymore.

All the more difficult for me to believe that.

Including base plate?

Does anyone know what these small devices similar to "cordless screwdrivers" used for tying rebar are called?

You mean a drilling device for twisting?

The extreme price range here always shocks me again, both in one direction and the other.

The harder it is for me to believe that ;)

A decline in building applications by how many %? Would that break the back of the shell builders?

There aren't many alternatives for paving and garden work either if no one is building and is rather investing their money in heat pumps due to rising prices.
