I haven't seen a construction guide, but I think it all depends on the circumstances anyway.
A base build order would be:
*Search tower and workshop on day one (crucial)
*great wall, and great pit after (if possible the Wall also on day 1)
Depending on the water supply go for pump earlier or later, and also the veggie plot. After that it's just upgrading whatever defenses you can in order to stay ahead of the zombie growth
I haven't made it past day 10 yet
We needed emergency defenses and everything, but I think it's best to avoid those if possible, building foundations and other upgrades instead/
Though I'm having great fun where I am now, I wouldn't mind switching over. But I'd like to see some stats on who's playing first
