helping a friend remodel a story and 1/2. we took out the opening between the kitchen and small dining room it had a had a 5' door opening with 2' foot walls on each side, the header that's in there is a doubled 2x10 running the whole length, he wants a smooth transition or at worst a small header and smooth walls. I don't think its a supporting wall, runs parallel with the second floor joists. the work is odd, the header sits under two 2x4s running flat with plywood sandwiched between. I'll try for a picture if that helps. Can this come out?
