About Us

WI Building Systems is a leading manufacturer of high-quality prefabricated and modular structures. Our modular buildings work to each client’s budget, without sacrificing on beauty, performance, or functionality. We’ve built a wide range of modular buildings including change rooms and sports facilities, office administration buildings, sales offices, food and beverage bars, cool rooms, freezers, switch rooms, schools and early learning centres, clinics, and equipment shelters.


We understand that in order to adopt the best solutions for modular builds, we need to have the right people. Our end-to-end service is handled by our professional and qualified team of engineers and production workers with a wide range of experience in manufacturing and construction. All our work is led by director Wally Ibrahim, who formed WIBS in 2016, after working for 25 years in the modular building industry. Wally had the vision of designing prefabricated modular buildings that are innovative, sustainable and cost effective.

WIBS has gained an extensive and loyal customer base, and by specialising in inclusive, accessible, and modern community centres, it has been able to take advantage of the increased demand for a healthy, outdoors lifestyle. This demand has awarded WIBS tremendous growth and shows no signs of stopping.

Through this, we adhere to our principles that new builds shouldn’t cost the world. WIBS ensures that our prices match our clients’ budgets, without sacrificing on quality or safety.

WIBS prides itself on supporting Australian jobs and using local materials.


WI Building Systems manufactures a large number of modules each month. We use the latest design tools and production methods and equipment to deliver our modules, and our facilities meet the ongoing demand of projects to meet clients’ expectations.

  • Modern factories and offices
  • Large production areas
  • Strategic location to serve metro and regional Melbourne
  • Ability to complete multiple small to large projects at one time

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
What makes WIBS unique is our focus on accessibility, cost and schedule, and quality.
