12×30 Custom Lofted Barn Shed with Spray Foam Insulation & Custom Windows
Premium Finished Building – $25,000
This 12×30 custom-built Lofted Barn shed is a one-of-a-kind, high-quality structure originally purchased through Serious Sheds and significantly upgraded beyond standard shed construction. Designed for durability, comfort, and long-term use, this building is ideal for a workspace, studio, business use, storage, or conversion-ready structure.
The shed features a classic lofted barn design with 7-foot walls, providing excellent interior volume and overhead storage potential. It was custom ordered with extensive window frame-outs to maximize natural light, creating a bright and usable interior environment throughout the building.
After purchase, the shed was further upgraded with spray foam insulation, dramatically improving temperature control, energy efficiency, and sound dampening—making it suitable for year-round use in the Pacific Northwest climate. This upgrade alone represents a substantial added value over standard sheds.
Built with engineered tongue-and-groove flooring, upgraded floor framing, house wrap, vapor barrier, and additional wall sheathing, this structure was constructed with longevity and performance in mind—not as a basic backyard shed.
