This image shows a doorway to be cut into a non-loadbearing wall. The wood elements outlined in red form the edges of the doorway. This is a job for a structural engineer.

If the wall is brick- or block-clad, masonry is removed slowly, and angled steel posts placed, until it is possible to insert the header. A header is needed for any opening in masonry, no matter how small the span.
