I see the high wall, my kaki shaking already.
The more higher of this rubble wall the more risk it will fall if stress. Somemore straight 90deg up without angle slope.
did @ts say how high the "back-wall" is ?
the problem with this kind of stone/stacked wall, is there is this little little gaps that allow water to flow out..
sometimes this flowing out water causes under soil erosion.... those that have GI pipes running underneath the hall/porch/garden will know when leak hahahahha
not sure for this case.. but better for ts to check with the Majlis what is the proper method, or consultant.. common sense logic will say for double story extension yes.. need go go until the main "footing" of the land/soil...
for single story there isn't much stress, except for the pillar and roof... compared with a full double story extension where u need support the RC flooring slab the upper walls and pillars and etc.. the weight itself is.. "alot"
unless your consultant say OK.. better make sure he provide planning documents and sign off on it...
if anything happen make sure SUE HIM KAU KAU including the contractor.. make sure they bankrupt so that won't cause harm in the future
