Engineered for strength, security and long-term use
Ranbuild’s triple garage designs focus on practicality, long-term reliability and everyday function. Each structure is engineered for strength, using high-tensile steel frames, strong walls, precision-built connections and rigid roof systems to ensure stability across all weather conditions.
Our garages deliver excellent security, helping to safeguard your vehicles, tools, and belongings from the elements and unauthorised access. Durable cladding, premium fixings and optional upgrades such as insulation and internal linings help maintain comfort and usability inside the structure.
The flexibility of the three-bay design gives you the freedom to organise your garage however it suits your lifestyle. One bay might be dedicated to parking, another to workshop activities, and a third for storage space or your recreational gear.
Ventilation and windows can be added to improve airflow, minimise heat, and create a brighter working environment. Gutters, downpipes and drainage considerations can also be built into your design to enhance performance across different region types.
Purpose-built triple garages for every property
A Ranbuild triple garage shed is a smart choice for homeowners wanting serious storage. With ample space for three vehicles plus additional room for shelving, benches or equipment, it offers more versatility than a standard double garage. Many customers use the third bay as a dedicated workshop, a place to store household items, or a secure area for seasonal gear.
These garages come in standard sizes, but can also be customised with different dimensions, length, and bay configurations to suit your location and layout. Choose from gable roof or skillion roof designs depending on your preferred style, drainage needs and the surrounding structures on your property.
Inside the garage, clear spans provide plenty of open space for parking, storing tools or organising equipment. Optional extra windows can be added for more airflow or natural light, while insulation upgrades help regulate temperature year round. If you want to add optional extras such as internal walls, gutter upgrades or security enhancements, we can incorporate those into your shed build as well.
Because a triple garage offers a significant amount of internal volume, it’s also ideal for people who want a dual-purpose area—parking and workshop, vehicle storage and hobby room, or simply more flexible room to grow in the future.
