We have a standard semi detached Victorian home. We are converting our existing loft with small dormer to a full size mansard.
To do this we are being asked to put in 4 steels. 2 above the existing floor, 2 in the ceiling. Because the existing floor joists runs the wrong way, we are being told to put the beams on top of the existing floor. Which loses us about 220mm in height. Worse it means the existing bathroom,
Which is on the eaves side is pushed up and becomes smaller than it is now.
Is there a way to avoid raising the floor. Such as flitch plating the existing joists? I asked the architect, he said the only way was steel beams on top. I just want to make sure I’m getting accurate advice for peace of mind.
