This is a fairly standard shed size used to store just about anything, from boxes of unused possessions to the yard or garage tools. The double doors simplify loading and unloading, particularly if you want to keep lawn mowers, snow blowers, or snow machines inside it. This shed has natural fresh air ventilation in the gable ends on both sides, which provides plenty of fresh air so that fumes from any yard equipment you store inside it won't build regardless of outdoor temperatures. Everything about the shed is built onsite except the vents, which are readily available at home improvement centers. Paint the louvered vents the same color as the shed, or use a contrasting trim color to accent this feature.
