Hey Martin, thanks for that.
If you see from the plans, the roof is supported on 5 'trusses' which are really just walls except that one with the pillar. The
only changes we are thinking about from what you see there are:
- removing the upright beam right in the middle of the main room
- wondering about the partition from eave height upwards on wall 3 - can't see what it does unless it's for longitudinal bracing?
So we're not wanting to turn the whole thing into open plan, and it is only one 'truss' we want to modify. We are taking out no walls at all, these are all specified by us.
Even so, as you say that will distribute some load to the outer walls but the roof is very lightweight - shingles. If you look at the middle of wall 5 you can see they actually already beef up the outer wall (between the windows they have basically built an intersecting pillar), we could do more if required:
We aren't planning to just go bodging this in, just to clarify. If the company isn't able to do it in a timely way we'd get someone to sort it properly but I'd like to ascertain what should be possible in layman's terms, get a few ideas.
In hindsight, I might have made more alterations but realistically, what I'm essentially proposing is to make this change:
- Remove the red upright
- replace the bottom two rows (orange) with a single-span member of some sort.
Actually those part numbers #085 are the little strengthening 'pillars' they build to support the 'truss' on the main walls.
