The 12-stall barn is designed with a similar drainage system as the main barn, featuring rock and sand layers topped with stall sheets that allow urine to drain effectively. It includes eight 12×15 stalls and four smaller stalls, each with solid walls, and windows for all but three stalls. The barn has an exhaust and automated lighting timer system to prevent horses from growing a winter coat. At the back is a garage door with a full-length matching stall door. Adjacent is a grain room with a stainless steel counter and tool storage. The 10-foot-wide alley offers ample storage space. Heating is provided via a boiler, with a utility room and bathroom located beneath the staircase, which leads to a hay loft storing approximately 1,500 small square bales, with doors over most stalls for easy bale dropping. There is also a small heated room suitable as an office or tack room. Outside pens equipped with HiQuil panels and automatic waterers are accessible, with a hydrant nearby and a concrete manure dump for stall and pen cleaning.
