Consult local building codes before assembly. This garage shed kit must be built on a flat level foundation of wood or concrete (not included). Flooring must be anchored to the foundation. Anchoring hardware depends on the type of foundation you have and is therefore not included in the shed kit. Not including the installation of the foundation, you can expect assembly of the shed itself to take 2 adults up to 8 hours.
