We are planning to open a doorway in a wall and now the carpenter is uncertain if the wall is load-bearing and if we need to insert a beam. We have received planning permission for the facade change and no construction drawings were requested, and I have assumed that the wall is not load-bearing...
It is a 1.5m wide doorway in a gable wall of a plastered house in Gothenburg built in 1950. All walls are wood. I am attaching all the drawings I have.
Do we need to insert a beam in the wall? Is there anyone who dares to comment based on this information?
You mention a door opening.
But what should be outside the door?
Personally, without being an expert on this, I see no problem with creating the opening.
It will be the same as with the window to the left on the same wall.
How is it done there?
A gable wall only supports its own weight, so there are no static problems with making an opening for a door. The house has a plank frame even in the gable, which must be reinforced at the top of the opening. For that, you can use a plank piece from the hole cutting. With the number of different layers included in the wall, making the hole can be a bit laborious.
Doorway you write.
But what should be outside the door?
Personally, without being an expert on this, I don't see any problems with opening up the hole.
It will be the same as the window to the left on the same wall.
How is it done there?
Outside the door, there will be a staircase down to a patio.
Unfortunately, I don't know at all how it is done at the window, the wall is made of underlying Tretex and plaster...
An end wall only carries its own weight, so there are no static problems with making an opening for a door. The house has a plank frame even in the gable, which must be supported at the top of the opening. For that, you can use a plank piece from the opening. With the number of different layers that are included in the wall, the hole-making can be a bit labor-intensive.
Thanks! So is a plank a few centimeters enough as a "beam"? How wide?
A gable wall only supports its own weight, so there are no static issues with creating an opening for a door. The house has a plank structure even in the gable, which must be offset at the top of the opening. For that, you can use a piece of plank from the opening. With the number of different layers included in the wall, making the opening can be a bit labor-intensive.
Now, what you say in this case applies to the fact that the gable wall does not support anything other than its own weight. However, there are buildings that have a ridge beam resting on the gable walls, in case someone else stumbles upon this thread with a similar concern in the future, but with a construction different from TS.
The normal practice is that the plank is as wide as the plank frame. Its both ends are recessed into the surrounding standing planks. All older carpenters know how to do this.
