Hi thinking of underpinning basement and Demolition is required prior

our basement is about 1000 square feet

has one small powder room and utility room as well as laundry room

i got a quote from general contractor for $10k for demolition and $80-90 k for 2.4 feet underpinning

he said also to finish basement with kitchen, 3 pcs bathroom, 2bedroom with closet will cost another $100k

that is total $200k for underpinnng and finishes does this price make sense? i feel especially finish is too expensive? how about 10k demolition cost?? should i do my self for demolition?

i live in toronto

one more question, if I am planning to add secondary addition on exsisting basement and main floor addition, is it recommended to underpin prior to addition??

photo is our basement thanks for reading
