Removing a load bearing wall. 1) a bearing wall supports structural load such as roof & 2nd flr & transmits this load to the ground thru foundation system. Removing this wall requires knowing how much load is being supported over how much distance. 2) cheapest way is to install an engineered wood or steel beam below existing floor joists 3) Another way is hiding beam within floor joists which are cut away to provide space for new beam.
