A word of warning - a 5m beam will be really heavy - like very very heavy. Weight could be an issue indoors - like the whole thing disappearing through the floor boards! Good builder and engineer may have an easier solution. Unfortunately, I am neither.
My experience of one 3m ish beam gives me and my builder nightmares - trying to get it to ceiling height was a ‘challenge’. My builder still mentions the danger now.
