klmt 3ft is quite narrow - envision trying to move furniture down a hall that narrow. If possible, tear down hallway walls where they border living areas - if the hallway begins or ends behind a living room, bkfst rm, etc... then tear out that partof the wall to make the actual hall passage shorter - but you'll still have to move bedroom furniture to the end of the hall - also, halls are total wastes of square footage, so tearing down any portion of a wall, even if you have to leave a column and/or header, means not only is the hallway effectively wider, but the adjacent room just gained 3 ft of space! Now you can have a console or hutch or artwork, whatever, on the hall wall, that's part of the adjacent room! win/win
