Hold E on a wall you built and a wheel opens with a large, clear picture of each choice in that wall’s own material: a stone wall offers a stone doorway, window and half wall, the other walls in your pack, and a pry bar to take it down. The one you point at fills in copper, the middle names it and says what it does, and letting go of E applies it.
Every doorway now has a flat stone step outside and a split-log threshold at floor height above it, so the way in reads as stone, step, door. The ground under and around a cabin is bare, so grass no longer grows up through the floor or against the bottom beam. The log doorway is taller and the log window a slim frame with a sill, to match the wall beside them.
