A structural wall actually carries the weight of your house, from the roof and upper floors, all the way to the foundation. Exterior walls are always load-bearing, and if there is a previous addition involved, some exterior walls may now look like interior walls, but they are almost certainly still load-bearing.
Thereof, can you take down a load bearing wall?
Removing a load bearing wall in your home is not considered a DIY project, since it can result in injury and structural damage if not done correctly. When removing a load bearing wall, the load must be supported temporarily while the wall is removed and a beam strong enough to carry the load is put in place.
