What materials are the large 11ft sheds made of?
They are made from high-density polyethylene (HDPE), same as any other lifetime shed. They are resistant to cracking, fading, rot, and rust.
Do I need to maintain it regularly?

Is it easy to assemble a large 11x21 or 11x18.5 shed?
Yes, the shed comes with user friendly installation manuals that are extremely detailed. You can assemble one using basic tools in approximately 8-12 hours, depending on your skill level.
