Removal of raise platform by the front door
I have a house built in late 80s in San Diego, when it was fashionable to have those drop floor. My house has a raised area by the entryway (foyer room) then it drops about 6″ on both side to the 2 adjacent rooms. I have a few questions:
1. what do you call this raised platform?
2. I want to remove this as it’s such a trip hazard, anyone has experience with removing platform like this in souther california area?
3. is it conventional that these raised platform be a monolithic block with the foundation or would it be a cold slab on top of the foundation?
4. How would I know how is slab platform concrete is poured? (cold joint or monolithic)
