Extending floor joists

[goodbyegti]

The family have gone away for half term, so I decided to move the stairs.

 

I need to extend the joists attached to the trimmer, so that they can be hung off the wall. The trimmer won't be supported at both ends, so I think it has to go. Or I need to seriously beef up the joist it's hung off. So I was wondering if anyone has used splice plates to extend joists? I would be adding them right in the middle, near where the sparky has routed all the cables.

 

The original plan was to replace each entire joist with a full length one, but you guessed it, I need to cut literally every service including almost every wire to the consumer unit if I do that.  Perhaps I should get on with it?

Bolt a joist to the wall Fix hangers on the joist and on the trimmer Back to back with what is already there 

Such a short span will be fine
