All sounds reasonable to me. Why does it seem a 'crazy' lot of work? (Maybe I'm missing something).
Got a bit of a problem with our newly acquired very run down 1880’s Queenslander.
Either originally, or as part of some very old reno work, the veranda bearers (which run perpendicular to the house) have been notched into the wooden stumps underneath the house bearer and ant cap.. but sit atop the perimeter stumps, which are set at a lower level. You will see in the pic’s the direct termite route..
For several reasons, we need to raise the height of the original veranda a touch, due to some very low clearances at street level.
The once full wrap around 1.8m veranda has been built in over the years, and the subfloor has been built up, so we effectively have original 120mm beam, original 120mm joist, original 22mm deck board, new 100mm joist, new floor board all layered up...
To raise the 120mm or so I need, I’m just assessing whether I can remove the original bearer and joist, replace the decaying facia/bearer with a new 5x3 bearer and just lay the new joists on that, sistering up with some of the old 5x2 joists for the extra length?
I know this is a crazy lot of retrofit work, just for 120mm, but the alternate is a full restump and raise (inc. double chimney)
Viable, or am I crazy?
Thx

Just the work involved in trying the thread through the joists for sistering up, inserting a 5x4 bearer basically around the whole house, where there's currently a 10 x 1.5 inch facia/bearer - not just the veranda but also the built in parts of the house.
my intent was to do this without removing any existing floorboards etc.
Yeah, ok, that does sound more complex, and the fact it's around the whole house (should have realised, being a Queenslander design).
It will take time, you'll make some mistakes (hopefully not disasters), learn lots, probably increase your tool collection, and get better as you go. Get some quotes (may as well), and you might get some ideas on how to go about it when they do site visits
The design of the original veranda appears to be the same as a traditional veranda using tongue and groove boards, these were built with slope on the boards to shed any water that got on them.
Check if the current inbuilt areas have slope away from the house, if not it may have been compensated for in the structure built over the original.
No reason that should stop you from building an even higher level floor but may impact the work to get your end result.
