Hello dear forum, I need advice regarding a wall opening.

We want to enlarge the passage between the kitchen and living room by removing a wall. A company has already visited and provided an offer. The wall will be removed, and the ceiling will be supported with a beam (HEA 160, marked in red). This beam will rest on the interior wall. The width of the opening will then be approximately 2.90m (9.5 feet). So far, we have understood this.

Now my question: Where can the beam rest on the exterior side and why (location marked with a red arrow)?

The company proposed installing a second beam in front of the wall, which the “ceiling beam” would rest on. The reason given for this option was that it would avoid having to open the masonry and reduce the risk of damaging the insulation.

For aesthetic reasons, however, we would prefer the beam to rest directly on the masonry, so that no additional beam is visible in the room in front of the wall.

Is there any reason against the option we prefer? Should we rather look for another company that feels confident executing our preferred solution without causing any damage?

Thank you for your input.

I would generally always get comparison quotes, that way you can also see what other companies say about the feasibility of your request. Without knowing the exact conditions, anyone would just be guessing here. Structural engineering is the key term. Happy New Year!

An additional vertical beam always increases load-bearing capacity, so it is structurally sound. For appearance, it can be covered with drywall to blend in.
Whether it can be done without depends on the structural engineer you or the company hires.

Thank you for your feedback. Yes, the final decision will be made by the structural engineer we hire. My question was more about whether there are general reasons (beyond structural concerns) not to rest the beam directly on the masonry but instead on an extra vertical support. I want to be better prepared for the discussion with the next contractor regarding the pros and cons of each option.

A drywall covering would already be included in the version with the vertical support beam.

Well, the thickness of the exterior wall probably plays a major role, as well as what exactly is inside it. In your case, the transition to the bay window is also happening right there, which could be a crucial factor.

For a serious assessment, more information would be needed than just the floor plan (and even then, only the one of the directly affected floor). Nevertheless, I will speculate that the beam penetrates into the roller shutter box and the ring beam.

What insulation? – I rather suspect this is a brick veneer; in the sloped-wall buildings of the 1980s, external thermal insulation composite systems (ETICS) were not yet used.
