Huh that is really expensive. According to Fixr, average cost per square foot is $117 [0], so Cover is ~3x as expensive. The benefits of going prefab would have to be pretty extreme to be willing to do that
Also to confirm what Alexis is saying about LA... We’re in the middle of our project and though we’re doing it on the cheap it’s mid 200’s per foot. Can easily see how it could be double that.
