I am needing to raise my sunken living room 7" to be flush with existing floor. All the outlets and windows are fine as is and the cieling is vaulted so that isnt an issue. Right now there is a crawlspace below and the existing floor is just on joists. Becuase of this I dont think concrete is the answer. I was thinking of running new joists on top of the existing and just then adding insulation between and 3/4 TG subfloor. My questions are:
- Since the new joists need to be 6.25" with 3/4" sub to get my 7" to level should I just use hangers and 2X6's or use a 2X6 fured out with 1X2's?
- If fured, put them on the top or bottom?
- If fured, Should I glue and nail the joists?
- If fured, Should the go parallel or perpendicular to existing joists (image shows current joist direction)?
