Finally removed all the lintel and tidied a bit in the laundry. The laundry will be gutted and rebuilt when the major renovation at the rear commences in the coming months so not worried too much what it looks like as the new wall will be covered with villaboard or something. Has blow in insulation above the cement sheet so thought I would close it up again temporarily.
