Hi,
I am converting my loft and i have a question regarding how best to fix the new floor joists.
We are lucky with the construction of the house; the new floor joists can run from the current inner wall plate under the eaves to the central spine wall.
My question is how best to fix them.
option 1 - lie the joists as close to the current rafter as possible and fix to the side of them.
option 2 - lie the new joists in between the rafters and fix the overlapped ends in the middle.
Both options have the downside of only one end being fixed; but i am unsure what is best.
BC are happy with the general design and the engineer has specced the joists as 47*225.
Thanks for your help.

- They will rest on 18mm packers so that they do not touch the ceiling below.
- A dwarf wall will be built off them around 1m from the eaves in place of a purlin.
- Current rafters and ceiling joists have plenty of twists and bends
BC are happy with the general design and the engineer has specced the joists as 47*225.
Thanks for your help.
