Modular Panel System — FAQ

Please reach us at info@underthedome.com.au if you cannot find an answer to your question.

Our Modular Panel System is a premium, semi-permanent decking solution built from heavy-duty structural components with a durable decking surface. Each 2m × 2m panel connects seamlessly with others to form a clean, stable platform.

It’s designed for outdoor living, glamping, events, modular builds and commercial spaces where speed, presentation and flexibility matter.


Installation time depends on site access and ground conditions, however most platforms can be installed in hours rather than days. Making the system ideal for projects with tight timelines, limited access, or remote locations where traditional builds are impractical.


Yes. Each panel is supported by adjustable levelling legs, allowing the platform to be precisely levelled on uneven or sloping ground (within reason).

This is one of the system’s key advantages over traditional decking, which often requires excavation or fixed footings.


The system is best described as semi-permanent.

It is:

  • Strong enough for long-term use
  • Designed to remain installed for months or years
  • Also able to be removed, relocated or reconfigured if required
     

This makes it ideal for glamping operators, venues and modular projects that may evolve over time.


 Approval requirements vary depending on:

  • Location
  • Site conditions
  • Intended use
  • How the platform is installed 

We recommend checking with your local council or building consultant if approval is required.

The Modular Panel System is designed to minimise site disruption and is often preferred where a relocatable or modular platform is needed.


 Each panel measures 2m × 2m (4m²).

Common size examples
