Space around the opening
A beam bearing on masonry needs suitable wall sections at either end. With a frame, columns provide support. Both options affect clear width and cladding. Discuss the finished space rather than only the rough opening.
Look below the steel
Loads under a column can be more concentrated, so the supporting floor and foundations also need assessment. A narrow column does not mean a minor floor intervention. Compare complete designs including feasibility, underlying work, access, installation and finishes. The steel price alone does not describe the whole project.
Your checklist
- Agree on finished clear dimensions
- Ask about visible beams and columns
- Compare complete structural solutions
