i work for the general contractor.
i am actually in an office, working as a project coordinator/estimator.
if no one wants a house built at the moment, you either build a spec, or find ways to get your specs sold... either way, you never want to be sitting there with nothing going on.
luckily though, the area i am in, and the compnay i am with have not been slowed down at all. last year was actually our strongest year ever for the company. this year we are expecting to be a bit slower, but still not an awful year.
