this is a hardware upgrade which you can't do it afterwards, you may regret not spending the $2,500 after you take possession. 10 ft basement may not be possible for a 2 storey because the public sewage might be well above your house drain- out pipe if excavation of soil goes a bit deeper. Ask your builder and they would tell you yes or no.
