Modern design. quality manufacturing.

WI Building Services is a Melbourne-based company that designs, manufactures, and installs modular buildings. We work with clients in local councils, industry, construction, and commercial businesses. Operating out of our two Craigieburn factories in Melbourne’s north, we provide prefab solutions for clients across Victoria and Australia.

Why build modular

Modular buildings are quicker and cheaper to build than regular masonry, while still offering the same quality and flexibility in design. The efficient construction process means there’s less waste and less environmental impact, and the factory where the construction takes place can be better controlled for safety hazards, so everyone wins.


We provide end-to-end support throughout the lifespan of the project and offer a holistic view to construction. Our goal is to make the project as easy as possible for you, so you can get back to doing business as usual. This means we cover:

  • Design and drafting
  • Offsite manufacture
  • Site preparation
  • Additions to existing buildings
  • Transport to site/client
  • Installation of the building on site
  • Handover to client
