About our Company

NWSM (Northwest Shedmasters) was established in 1998 and today has grown to become one of Western Australia’s leading design and construction specialists. In the past five years, Northwest Shedmasters has expanded its services to include a Garage Door division based in Perth (NWSM Garage Doors) and a Sheetmetal division in Broome (NWSM Sheetmetal), and during this time the growth of our industrial/commercial projects has increased in the Northwest region of the State. As a result of this growth, we decided to brand all of our divisions under the one name, NWSM Building Group. We are still the same company that has been successfully in business for more than 16 years, we’ve just expanded!

NWSM Building Group provides quality engineered projects specialising in Civil and Mining Building Construction, Steel Building Systems, Warehouses, Showrooms, Workshops and Aircraft Hangars. Our portfolio also includes Industrial and Commercial Buildings, Residential Sheds, Garages and Workshop sheds, Garage Doors and Sheet Metal, roofing and building supplies.  We are approved Government suppliers and leading cyclonic design specialists. All NWSM products are locally designed and manufactured in Western Australia.

Being Registered Builders, NWSM can provide a full turn-key customised design solution as well as in-house engineering. All projects are engineered to provide excellent quality and value, and our installation teams work closely with our design and engineering team to ensure that the best possible construction and safe work practices are constantly evolving and improving.

Servicing the whole Western Australian region, from Perth metropolitan areas, to regional and remote towns, our expert team will travel near and far to complete your project.

Building in remote locations within the cyclonic regions of the state has enabled us to provide experienced knowledge and expertise for cyclonic-resistant construction to withstand the harsh Western Australian climate.

Our Head Office is based in the northern Perth suburb of Wangara, and our Regional Offices are based in Broome and Bunbury. We also have staff based in Newman and Port Hedland. Please visit our contact page for more contact details.

* Sheet Metal, Roofing and Building Supplies are available from our NWSM Sheet Metal division located in Broome.
