Design the ultimate horse stable with shed designer.

What is a horse stable?

A horse stable is a steel-framed building organised around the horse's day, not the buyer's eye. The shell is just the easy part. What matters is the box size, the floor fall, the aisle width, the wash-bay drain, the tack-room layout and the ventilation rate inside each box. ShedDesigner's stable templates start with the welfare and workflow specs, and let the steel follow.

Stall count, aisle width and tack and wash-bay layout are all adjustable template parameters. Every dealer is third-party assessed under the Australian Steel Institute's ShedSafe programme.

Sizing the boxes

Three numbers anchor a stable that meets the welfare code and works for the horse.

Floor area. The NSW Animal Welfare Code of Practice No. 3 sets a hard minimum of 12 m² per horse and 9 m² per pony under 12 hands (NSW Department of Primary Industries, Animal Welfare Code of Practice No. 3, Horses in Riding Centres and Boarding Stables). The Code requires the stable to let a horse stand with its head fully raised, walk forward, turn, lie down, roll, and stretch.

Practical build target. 3.6 × 3.6 m (12.96 m²) is the most common Australian stable build. It clears the Code with a small margin and works for thoroughbreds, stock horses and most riding stock. Warmblood and draft owners should plan for 4.25 × 4.25 m boxes. The standard 3.6 × 3.6 m is too tight for the breed.

Ceiling height. Code minimum is 2.5 metres. For comfort and ventilation, 3.0 to 3.6 m is the working benchmark. Lower ceilings trap heat and ammonia, and warmbloods can hit a 2.5 m ceiling with their head up.

If you want the broader barn-shape angle (raised centre, hay loft, multi-use), see also our horse barns product page or the barns category.

Aisle, breezeway and ventilation

Three numbers most stable buyers underspec the first time around.

Aisle width. A private stable runs 3.0 to 3.6 m of clear aisle. A commercial stable for cross-tying and machinery runs 4.2 to 4.9 m (Hansen Pole Buildings; FBI Buildings). If two horses pass each other in the aisle, the wider number is not optional.

Air changes per hour. Industry consensus for stable ventilation is 4 to 8 air changes per hour, with 6 ACH treated as the working target (Penn State Extension, Horse Stable Ventilation). Australian summer is the design constraint. Plan ridge vents, gable louvres and per-box wall vents from the start.

Roof colour. BlueScope's published Solar Reflectance Index data shows Surfmist at SRI 81 (solar absorptance 0.33), Jasper at SRI 35, and Monument at SRI 27 (BlueScope, COLORBOND® steel solar reflectance properties, ASTM E 903-96, 2022). On a hot afternoon, Surfmist roofs run materially cooler internally than Monument. For stables, that is colic and heat-stress risk reduced.

Wash bay, drainage and tack room

The fit-out is where stable buyers usually overspend.

Wash bay slope. The working rule is a fall of 1:80 (about 1.25%) toward a back-wall trench drain, or a centre drain in the floor. General slab guidance allows 1:50 (2%) where steeper drainage is needed (System Equine, Wash bay drainage). Get the slope right at concrete pour, because retrofitting a fall into a finished slab is expensive and rarely satisfying.

Stall floor. Concrete with rubber matting on top is the most common build, easy to clean and durable. Compacted blue metal or limestone with rubber matting is a softer alternative some owners prefer for hoof health. Either way, slope the floor 1:80 toward the door so urine clears.

Kickboards. Industry minimum is 1.2 m, ideally hardwood at 38 to 50 mm thick, lined with rubber matting (Horizon Structures; Vale Stables). Some owners run boards full height in stallion or known-kicker bays.

Tack and feed room. The practical Australian floor is 3 × 3 m (9 m²) for a single-horse setup. 3 × 3.6 m is the barn-design industry "right-first-time" recommendation (Quarry View Building Group). Build the bigger one.

Before you get quotes

A 4-stable block kit lands roughly $18,000 to $22,000 before slab, drainage and fit-out (Guerilla Steel Stables, 2026; Sheds.com.au, 2026). Once you add concrete, fall, wash-bay drain, kickboards, matting and tack-room fit-out, the real spend is the inside, not the shell.

ShedSafe accredited dealers, no exceptions. Every dealer on ShedDesigner is third-party assessed under the Australian Steel Institute programme.

One design, multiple quotes. Your stable design goes out to dealers in your region. Every quote prices the same shell, with the same internal-fit-out specs, to the same engineering, so the quotes you get back are directly comparable.
