Floor Levelling

[lstevensuk]

Hi, Having removed a non structural wall to make my hallway wider I'm left with the last few rows of bricks. (Pipes etc I can sort). My question is how to best deal with the hole when I remove the row of bricks. 

 

Left side is solid all the way down, as you can see right is a suspended floor.

 

Should I just shutter it off and fill with concrete then level. Could also remove few bricks and add insulation - only the brick width!
Install a new joist and run my chipboard over the top?

Remove the left and put new joists and insulation in.

 

Think that's about all my options.

Left side is about 850mm wide right the same.
