Loft Conversion

Lowering ceiling joist

Anonymous user 15/03/2024 - 2.38 PM

I'm having a loft conversion done and I'm changing the roof into a dormer. Because of lack of head room I had to lower the ceiling joist. The work it's going OK but I'm having a concern regarding how is the floor joist supported. I was expecting the floor joist to go from the new metal bar ( I don't recall the proper name) to the acknowledgement of the flat and sit on the main wall bricks, instead the builder drilled long wood joist parallel to the metal joist and I believe they want to make all the new floor joist sit on it. Is it this normal? Doesn't this pull the main wall inward?

Depend on the span they should sit on low bearing wall if the span is to much you expect to se a steel beam in place , you should of had engineering calculations with your drawings , if you’ve had an architect design your loft conversion they should be following exacally what’s on the plan and should having building control to check work before anything is covered up , if you have any concerns call your Archectec or local building control ,
