COMMON QUESTIONS
Semi-permanent structures: FAQs
What is a semi-permanent building?
A semi-permanent building is an engineered structure designed to stay in place for months or years. It offers far more than a temporary marquee, yet avoids the cost and approvals of permanent construction. Every Affix structure is fully certified, weather sealed and built for long-term hire or purchase.
Which industries do you build for?
Aviation, defence, mining, oil & gas, construction and remediation. We engineer hangars, workshops, warehousing, covered work areas, containment enclosures and site buildings to suit each sector’s compliance and access requirements.
Can structures be fully customised?
Yes. We build custom spans and footprints with high leg framing, hard walling, inflatable roofing, industrial roller doors, flooring, power and fit-out, all engineered to your exact dimensions, loads and operational needs.
Do you install across Australia?
Yes, including remote and difficult sites. We manage design, supply, installation and demobilisation as one accountable partner, so you have a single point of contact from start to finish.
