9' is better, especially for walk-out basement. you will spend more time there than regular basement. (otherwise, no need for walk-out). ; x$ `, Y% j, T# [6 b, @laosan 发表于 2009-12-12 18:45

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.
