Hello everyone,

My wife and I have an urgent appointment next week and would like to have a wall removed between the kitchen and living room before moving in. The wall is marked in red in the picture. The wall is 3m (10 feet) wide and 24cm (9.5 inches) thick. Above it is a wooden beam ceiling, and there is no wall directly above it on the upper floor. The house is built solidly from sand-lime bricks. Attached is a view of the wall from the living room side.

How much does such a structural opening usually cost? The house is located in the Stade district (Lower Saxony).

It costs about one Saturday of work and half a case of beer if you do it yourself...

I wouldn’t have any problem tearing down the wall myself with a demolition hammer. Does that not affect the structural integrity, meaning a steel beam would need to be installed? How can I tell if it’s a load-bearing wall?

Well, that is something you should know in advance...

Yes, that’s why the statement about just quickly tearing it out on a Saturday is somewhat questionable. With a 24cm (9.5 inches) thick wall, it’s reasonable to assume it has a structural function. Especially if there is a real beam ceiling, the beams rest on it.

In that case, a lintel or support system must be installed to carry the load. This needs to be engineered and calculated by a structural engineer and will likely require professional installation. The question is always whether you actually save much in the end if you don’t have enough knowledge to properly assess and execute the work. I would advise being cautious in such situations.

That’s what the real estate agent and the expert during the inspection also said. They estimated costs around 3000 to 6000 EUR. Has anyone here done something similar and knows a more accurate estimate? After the notary appointment, I plan to get quotes from several companies.
