The photo attached shows both vinyl/ laminate flooring and carpet. My plan is to rip out carpet and install new vinyl flooring right on top of existing hardwood floors. Once I rip out carpet the carpet room won't be same height. Is the best option T- molding or 3/4 osb subfloor or just ripping out the old hardwood? Using the same vinyl through out the house and think it would look better with no T-mold.
