Build Tips
Open bags one numbered sequence at a time — LEGO orders them to match the build stages and keeps loose piece counts manageable.
Budget 4-8 hours across multiple sessions rather than one sitting. Fatigue leads to missed connections that are hard to trace later.
Keep the instruction booklet after building — it's the most reliable reference for disassembly, cleaning, or reassembly after storage.
