A dollhouse is really a piece of furniture with dozens of tiny fragile passengers riding inside it. Empty every room into labeled bags before you wrap the house itself, and both survive the trip intact.
Pro tip: Photograph each room's furniture layout before bagging pieces, so recreating the exact setup at the new home takes minutes instead of guesswork.
Watch out: Do not lift a dollhouse by its roof, turret, or chimney; these decorative points are typically glued, not structural, and snap off under carrying weight.
