Steam condition
Fully upgrade your house.

Plan the unlock
Keep the exact condition — Fully upgrade your house. — as the completion target. Open town repair questline for the relevant system, then check Steam’s own achievement state after completing the action. Your local tracker checkbox does not trigger the Steam unlock.
If it has not unlocked
Confirm the installed game version and compare your completed action with “Fully upgrade your house.”. The condition does not establish hidden prerequisites or retroactive behavior, so neither is added here.
Save your checklist
Mark the achievement in the browser tracker after checking Steam. Export companion progress if you want to move that checklist to another browser. No account or game-save upload is required.
Sources and version context
Steam 1.0 conditions; v1.0.5 fixes reviewed. Dataset checks are separate from the current game version; a patch review does not claim that every granular value was retested in-game.
