My understanding is that solid hardwood flooring [nail-down application] should be installed perpendicular to the floor joists.

Does this also apply to a floating, engineered hardwood floor ?

The reason I ask is that a parallel layout [with respect to the floor support] will be more visually appealing and avoid some transition challenges.

Thank you for your thoughts.

Thank you for your response.
The subfloor is plywood.
I am not certain of the thickness as we have not taken possession of the home yet [May 14th!].
I have scoped out a cross-section by removing a heat register in the floor.
Of course I was hoping to find hardwood but was relieved to not find particle board.

My understanding is that solid hardwood is layed perpendicular to the joists to prevent cupping that could result from the boards causing the subfloor to sag.
I imagine the same issue would exist with engineered hardwood.

I don't know exactly what your situation is like, but if you put down another layer of plywood, staggered to the first layer, I am sure it will be fine to put the floor whichever way you want. I have a room in my house 200sq ft that has nail down flooring parallel to the joists. Double layer of plywood though. New constructions, so I didn't have to worry about taking off the base moulding or trimming doors and trim.
