House parts only (a porch, a roof, a bay window …): for a piece on the playa use the playa tool, and for a pavilion on a prime plot the plots tool. Build a house part the whole way (your first is yours to build from what you gather; after that, parts are unlocked with glow): the trips to the wilds for what's short (each carried home to a pile in the yard), the made materials at the bench, then the building itself at home, in stages anyone can watch. Every step goes on your plan with real clock times; plan shows them and plan cancel takes one off. The same as do "build ". Neighbours can lend a hand with do "help build".
