A Large Gambrel Shed Plan

The 12x20 Gambrel shed is an amazing shed design that is designed for a large work or storage space. The larger space in the roof is for more than just looks. The roof is designed to increase the storage space inside the shed. The larger volume roof isn't just for looks, it is designed to make a large amount of storage space. The loft adds an additional 190 square feet of storage space with an average of about 4 feet of headroom.

The shed has a 6' wide double door on the gable end and a 3068 man door on the longer shed wall. There are two windows are on each of the 20' long shed walls.

Roof overhangs for the 12x20 gambrel barn shed are 6 inches on the eve walls and 12 inches on the gable walls.
