Building up a 4 season porch floor to match house floor level.
We are converting a 3 season porch to a 4 season. Is it ok to use 2x2s on top of 2x8 floor joists to add height to the porch floor without having to build up to the plywood to match the current house floor level? We are about 3.25 inches lower than the top of our hardwood floors in the dining room that the porch would transition into. Any other suggestions if this is not an option? Thanks!
