Based on 24 reviews Volumetric surveys define land in three dimensions (not just by area, but by volume) allowing titles to be registered above, below or within existing lots.
They’re commonly used in complex developments like podiums, basements, airspace lots, or mixed-use buildings where multiple titles must coexist.
Sonto delivers precise volumetric plans for registration with the Titles Office, supporting clear vertical boundaries and enabling efficient, compliant project structuring.
We begin by reviewing your development layout and title strategy to determine how vertical lots will be defined, such as above ground, below podium, or intersecting other lots, ensuring alignment with planning and legal frameworks.
Our team conducts a 3D site survey to map all relevant structures, levels and reference points. This data forms the foundation for defining each volumetric parcel accurately within its three-dimensional position.
We prepare a certified volumetric plan showing each parcel in relation to fixed reference points, defined 3D parcels, and adjoining lots. The plan is drafted for compliance with Titles Office standards.
We issue the certified plan digitally and provide supporting information required for legal or Titles Office lodgement. If needed, we coordinate with your consultant or solicitor to help streamline the registration process.

Contact us for a quoteVolumetric surveys require more than just measurement. They demand spatial accuracy, legal compliance and smart coordination.
Our team works with you from the outset to define your 3D parcels efficiently and deliver certified plans that support fast, clean registration.
We clarify how your vertical spaces are structured (including basements, podiums, or airspace) and how these need to be defined for titling.
Using advanced survey equipment, we capture the spatial coordinates and height data needed to define each volumetric lot accurately.
We prepare a certified plan showing each parcel’s 3D boundaries, anchored to survey reference points and fixed structures.
We certify your plan and deliver digital files ready for Titles Office submission or legal attachment to titling documents.
A volumetric survey defines land in three dimensions, rather than just length and width. It’s used to create titles for spaces above or below ground — like podiums, basements or airspace — where traditional boundary surveys don’t apply.
Volumetric surveys are required when separate titles need to be created for parts of a development that exist above, below, or within other structures, like retail under residential lots, airspace lots, or services running under roads or podiums.
Yes. That’s the main purpose of a volumetric lot: to allow separate titles that occupy overlapping or stacked spaces within a development. Each lot is clearly defined in 3D, avoiding boundary conflicts and supporting complex project layouts.
A volumetric plan includes detailed spatial definitions of each parcel, showing its height, volume, and relationship to fixed reference points. It’s prepared for compliance with Titles Office requirements and is certified by a registered cadastral surveyor.
Not always. Strata and community title schemes often use standard boundary or building format plans. But if your development involves layered or overlapping parcels, a volumetric survey may be required to legally separate and title those spaces.
