This video takes a deep dive into the Allen Barndominium, a fascinating shell-only project that recreates our fan-favorite Hilltop plan with major functional upgrades and a distinct off-grid twist.

Perfect for those interested in the construction process or planning a DIY finish-out, we show exactly what a shell-only package includes — from the burnished slate exterior and 6/12 pitch roof to the massive wraparound porch that encircles the living quarters for both aesthetic appeal and functional shade.

Unlike the original Hilltop build that used glue-lam beams, this project features 16-inch open web trusses for easier mechanical runs and an increased eave height, significantly improving the usability of the upstairs space. This turns it from simple attic storage into a viable efficiency apartment or conditioned storage area with much better head clearance.

The 900-square-foot downstairs layout includes a comfortable one-bedroom, one-bath setup, a walk-in pantry converted to a coffee bar, and a dedicated mechanical room designed to house large battery banks, as the entire structure is 100% off-grid with no external power connection.

We show how standard 2x6 stud framing integrates with the steel structure, using the Zip System to create a complete thermal envelope, ensuring maximum efficiency just like our turnkey homes.

The attached 1,800-square-foot shop provides ample space for woodworking, featuring two large overhead doors and high clearance for versatility.

We also touch on the cost-effectiveness of shell builds, which can run around $100 per square foot depending on specifications, giving you the freedom to finish the interior at your own pace.
