Especially in older existing buildings, the individual rooms are usually small. It is close to the idea of enlarging rooms by removing an inner wall. Here you can read what to look for and how to proceed if you want to remove an interior wall.
Room requirements change over time
The layout of rooms in a new building is largely planned according to the client's requirements. But these requirements can change significantly over time. Be it through family growth, children move out or a building has new owners.
How was an interior wall made?
Many houses are a compromise between building costs and requirements in terms of room size. Therefore, there are quite a few smaller rooms in buildings, especially in existing buildings. The idea is obvious, simply by removing an inner wall from two small to create a large room. But here already a first distinction is necessary:
- Interior wall masonry (in wet construction)
- Interior wall of drywall (in dry construction)
The removal of a drywall is relatively fast and easy to accomplish. More information can be found in the linked guidebook.
Statics: load-bearing or non-load-bearing inner wall
You can not easily lay hands on a bricked inner wall. For masonry interior walls can be load-bearing or non-load-bearing walls. A first clue to this can be provided by the existing roof truss.
The roof truss is manufactured either as a purlin roof or rafter roof (or a construction made of it like the pitched roof). The rafter roof derives the weight over the outer walls, the purlin roof on abutment pillars within the building footprint. Ultimately, however, a structural analyst should be interviewed so that it can be ruled out to remove a load-bearing wall. Vorbereit Prepare and switch off building services
Once these points have been clarified, the existing building services must be prepared. Preferably, current and / or water should be turned off in existing lines and / or pipes. In particular, in the presence of plumbing installations, they require corresponding components for sealing the pipes (blanking plugs, for example). Electrical cables are dismantled and then brought together in a junction box.
Direct preparation for removing the inner wall
Now the actual demolition of the inner wall can almost begin. You still need large plastic tarpaulins to protect any furniture or other spaces against the significant dust. If you do not want to move the rubble twice (out of the house and then into the container), you may also have to order a building rubbish container in advance. To ensure that the building rubbish container is correctly dimensioned, you can calculate the building rubble density in advance.
The removal or the demolition of the inner wall
Now the removal of the inner wall begins. You need a miter with appropriate stone chisels, a sledgehammer and possibly a percussion drill with chisel attachments. With the miter and chisel, an area is cut off so far that they recognize the wall structure (where are bricks in the mortar bed).
First of all, you can simply knock out some bricks with a chisel in a mortar bed. Now, the inner wall is already so far that you can start the big sledgehammer. Beat the inner wall until just past the connection walls. The "fine work" then perform again with a hammer and chisel.
Tips & TricksIf you just want to remove a part of the inner wall, for example, to install a door, you still need to get the required lintel, which should be used as soon as possible. How to install a concrete fall, you can read here.
