Sup,
We are having a single storey extension out the back (mid terraced house). I had heard of these new steel box frames rather than a supporting steel frame rsj (which would be required to sit on brick). Instead, these steel frames are literally like a picture frame, they sit along the bottom of the wall, up the sides and then support the roof too.
Make sense?
If we have a traditional RSJ style beam, it will mean the internal walls will have a small pillar style kink in them, which we'd like to avoid if possible.
ie, what we don't want:
where it has to sit on the existing return of the rear wall.
and what we do kind of want:
Anyone done something kind of similar and where the costs drastically different?
