Start by crafting the Building Hammer (resource recipe available in the crafting menu) and use it to place new foundations — the core pieces that grow your raft. Foundations (regular, solid and triangular) are placed with the hammer and repaired with planks when sharks bite; expand outward in rows so you can hang collection nets at the edges to passively gather debris. Protect outer foundations with foundation armor or a buffer row and keep spare planks to repair damage. Building Hammer crafting and placement details. (raft-archive.fandom.com)
As you expand, add production and quality-of-life structures (grills, purifiers, crop plots, chests), then progression items — sail/steering, anchor and engines — to control movement and scale. Early-game tips: grow sideways to cover more drifting trash, place collection nets on the outer ring, and use triangular foundations to save materials on corners. Multi-floor builds let you stack functions without increasing base-layer foundation counts (engines and their rules affect bottom-layer foundations), so plan layout: storage in the center, farms and engines clustered for efficiency.
