Sample 30x40 Barn Layout
This small barn design has been adapted from our base 30x40 metal building kit package. The barn measures 30x40x12 and has been configured with two 10x12 sliding doors in the left end wall to allow easy access for large machinery and a further 10x12 sliding door in the front sidewall.
This setup allows you to create two independently accessible spaces within the steel barn. Other features include a gabled roof with a 4:12 pitch and a 3x7 walk door, and the barn is finished in fern green and almond with a fern green wainscot.
Please Note: Designs are for inspiration only. All barn kits are customized to YOUR specs.
