The NWSM Story

Founded in 1998 as Northwest Shedmasters, our family business has grown from a local shed builder into NWSM. Today, we design, fabricate, and deliver complex projects across mining, agriculture, transportation, aerospace, and government sectors.

As a family business, NWSM began with a commitment to never compromise on quality. From the start, we fabricated our structures locally and stood behind every one we delivered. That approach has taken us from regional workshops to aviation hangars, warehouses, industrial facilities and public infrastructure across

Proudly Western Australian

A statewide grounded presence that keeps us close to every project and every client

We remain a family business based in Perth, supported by a network of trusted regional partners. This approach allows us to deliver projects efficiently across Western Australia, from metropolitan areas to the most remote towns.

Safety comes first on every site, for our team, our clients and the communities we work in.

We apply safe practices at every stage, from preparing plans to delivering structures on site. We hold the certifications and qualifications required to meet the highest Australian standards, while prioritising the protection of our people, clients, and the communities in which we work.
