This smaller wall was likely a pantry or something when the property was built in the 50s.
Now it needs to be removed to make room for a new kitchen.
The wall is made of the stone/gravel material that interior walls were built with before, is it called lightweight concrete? Feels mostly like gravel...
How do I dismantle it in the easiest way not to damage the "real" wall behind?
I want a clean cut. A sledgehammer might take parts of the big wall with it, so I’d prefer to cut it somehow.
Angle grinder with a diamond blade?
