Pool rebuild?

Hello all, my wife has her eye on a new home for us. The pool that it already has is much too small for our family and friends. Is it possible to extend one end of an already existing pool? The pool is an inground gunite pool. It was probably installed when the house was built in 2000. There appears to be ample area to open up one end of the pool. I think adding an additional 10 ft outward would be sufficient. Im sure this type of renovation is pricey, but seems logical it would save money in the long run versus a brand new pool. All comments are welcome.
