Hello. I have a former exterior wall that is now an interior wall in the house, and I would like to recess an aquarium where this wall is. The idea is that the aquarium should be visible from 3 sides. I'm wondering if this is okay or if I need to incorporate a load-bearing structure like an I or U beam.

One side will be next to a staircase down

and the other side to the kitchen room

The wall is 120cm, so the entire area was intended to be removed to recess an aquarium with dimensions 120x70x70

Is it any help if you have trusses up there

Couldn't find any better pictures at the moment.
 
would probably have needed a pole on the corner in that case
 
What do you base this on? Enough what? Can you or just an idea?
 
an idea something should support the wall above and reinforce that beam shown in the picture over the opening not an engineer but have done something similar in my house
 
What does the wall look like today (pictures)?
What material is the wall made of?
How do the overhead beams relate to the wall?
 
Don't know exactly, but the house is from 1958 built by Swedish trähus so standing 2" I have seen in the rest of the house.

Original drawing and where the stairs are

The wall you want to change, was it previously one of the house's long sides? There should be a drawing where the extension is included, if you don't have it, you should be able to request a copy from the municipality's building permit department.

Right where the right railing is screwed into the wall, there is likely a load-bearing stud. Directly across the old entrance, there is likely a beam in the wall, one end of which rests on the stud you want to remove.

Yes, it was previously the house's long side. The extension looks like this and was done in 1972

but there is no problem with making a new post to the right of the railing by the stairs. But since we are going to put drywall on the wall, there is no problem to "check" what is behind the tretex panel.

Glued laminated timber post is not that expensive and easy to achieve good durability.
 
This type of beam is in the opening that needs support
Close-up of a wooden beam in a wall opening with visible nails and peeling plaster, discussing reinforcing with a post or beam for better stability.
So a post is necessary, but which is stronger?
Glued laminated timber post or a steel beam. Preferably as thin as possible without compromising durability and stability.
Tips on dimensions.
