Two ways to build.One company on the hook.
One4Build is a commercial builder working across New South Wales from the Illawarra — fitouts, new builds, remedial works and maintenance. We also design and deliver factory-built modular buildings anywhere in Australia.
Commercial building
Fitouts, new builds, remedial works and maintenance. Owner-led from the first meeting to handover. All sites, including sensitive live environments and tricky industrial settings.
Modular
Nearly any approved building, manufactured factory-direct and installed in days. Homes, units, hotels, offices, accommodation and workforce camps.
The next ten jobs
We would rather be your builder for the next ten jobs than the cheapest quote on this one. Most of our work is repeat work.
Owners on site
The company is deliberately lean. The people who quote your job are the people responsible for delivering it.
