Summary

A practical 3-bay indoor stable retrofit built inside an existing farm shed using Guerilla Steel modular panels. Each stall measures 4 m × 4 m × 2.4 m high, creating full-size horse boxes fixed directly to the shed wall and floor. The stable uses ply-and-mesh combination panels, delivering strong kick protection while maintaining airflow and visibility between boxes. By using the shed structure as the roof and rear wall, the owner created three durable indoor stables quickly and cost-effectively while keeping room to expand the stable line in the future.

3-Bay Indoor Stable Retrofit

  • 12 m × 4 m × 2.4 m (48 m²)

3-Bay Modular Shed-to-Stable

Our Northern Rivers customer needed an existing farm shed turned into a practical stable line without building a completely new structure. They already had a large machinery shed with unused space along one wall. Rather than constructing a separate stable block, the decision was made to retrofit three full-size indoor boxes using Guerilla Steel modular stable panels.

Each stall measures 4 m by 4 m with a 2.4 m height, giving horses enough space to stand comfortably, turn, and lie down. The stables are fixed directly to the shed structure and floor, using the existing building as the roof and rear wall. This approach significantly reduces build cost while still creating proper horse boxes suitable for daily use.

The panels use a proven ply-and-mesh combination design. Solid form ply kickboards protect the lower half of the stall from kicks and wear, while heavy galvanised mesh above allows air and light to move freely between boxes and through the shed. Horses can see each other and the wider shed space, which typically reduces stress compared with fully enclosed stalls.

By converting part of the shed into a stable line, the owner now has three dry, undercover stalls positioned close to feed storage, tack and yard access. The layout also leaves room to extend the stable run later if more boxes or a tack room are required.

Efficient Shed Retrofit Installation

The stable panels are mounted directly onto the existing shed wall and slab, using the shed structure for roof cover and rear enclosure. This avoids the cost of roofing, all rear panels and one end panel – while still delivering permanent-grade horse boxes.

Full-Size 4×4 m Stalls Ply and Mesh Panel Construction

Each stall measures 4 m by 4 m with a 2.4 m height, providing generous space for most saddle horses to stand, turn, and lie down comfortably while maintaining good ventilation. The stables use Guerilla Steel’s combination wall panels featuring 17 mm form ply kickboards and heavy-duty galvanised mesh uppers. This design balances strength, horse safety, airflow and visibility between stalls.

Undercover Stable Workflow with ride in access

Because the stables sit inside the shed, horses can be handled, fed and mucked out under cover. This improves daily workflow during heavy rain or extreme sun while keeping footing drier and easier to maintain.

Spelling or Rehabilitation Horses

Three consistent indoor boxes provide safe overnight stabling for spelling horses or animals recovering from injury.

Start up or Small Agistment Setups

A simple three-box layout works well for small or start up agistment operations where horses need occasional stabling without large facility overheads.

Bad Weather Horse Handling

Indoor stables allow horses to be groomed, fed, or managed under cover when weather conditions make paddock handling difficult.

Sliding Door Stable Fronts

Sliding doors can be installed on the stall fronts if the shed aisle space is narrow or if multiple horses are handled regularly.

Add a Tack or Feed Bay

One end of the stable run can be enclosed with the same panel system to create a small tack or feed storage area within the shed.

External Day Yards

Individual outside yards can be added in front of each stall to give horses access to fresh air and movement while remaining connected to the stable boxes.

Extend the Stable Line

Because the panels are modular, additional stalls can be added along the shed wall later to expand the stable row into a larger multi-bay facility.

Every Guerrilla Steel project follows a simple principle: build once, build right. The process focuses on practical planning, precision manufacturing, and long-term durability so the stable becomes a lasting asset—whether you plan to use it as a permanent structure or relocate and reconfigure the modular panels later.

  1. Design & Planning

    The process begins with choosing the right configuration for your property, horses, and daily workflow. Stable size, layout, ventilation, and site access are considered so the structure works with your land and long-term plans.

  2. Precision Manufacturing

    Each stable is fabricated in the Guerrilla Steel workshop using Australian RHS steel framing, welded panels, and durable roofing materials. Manufacturing in a controlled environment ensures consistency, strength, and long service life.

  3. Delivery & Installation

    Modular panels are delivered ready for assembly. Many customers install the system themselves using the DIY friendly flat-pack design, while others choose professional installation. Either way, the modular system keeps the build straightforward and predictable.

  4. Ownership & Maintenance

    Once installed, the stable becomes part of the property’s working infrastructure. Routine checks, cleaning, and occasional maintenance keep the structure performing for decades while protecting the horses inside.
