Empty ceiling cavity (Standard roof trusses) is a residential building-planning choice in the Price Your Build estimator. Roof-void use affects truss loading, access, insulation, ceiling detailing and service maintenance.
What this option means
Roof-void use affects truss loading, access, insulation, ceiling detailing and service maintenance.
Why it affects the estimate
The estimator uses this selection to establish an early allowance. Final cost depends on the approved drawings, site conditions, supplier system, installation method and contractor scope.
Before proceeding
- Clarify whether the void is maintenance-only or for storage, then coordinate access and structural design accordingly.
- Compare the final specification, exclusions and installation detail against supplier and contractor quotations.
- Confirm the relevant professional, municipal and product requirements for the actual project.
