Components: 2 · Property Types & Sectors (31000)

Overview

Mixed-use developments combine two or more distinct land use types, typically drawn from residential, retail, commercial office, and hospitality categories, within a single building or integrated development site. The classification distinguishes mixed-use property from single-use property categories on the basis of the deliberate integration of multiple uses, whether arranged vertically within a single building or horizontally across an integrated site, and the shared infrastructure, access and, in many cases, ownership or strata structure that integration entails.

Node 31700 serves as the parent index for two subordinate classifications addressing specific mixed-use typologies: Node 31710 addresses integrated residential and retail developments, the most common mixed-use configuration in the Australian market, typically comprising a retail podium beneath one or more residential towers; and Node 31720 addresses transit-oriented development, a mixed-use typology organised around, and integrated with, public transport infrastructure.

Mixed-use developments are typically assessed for both their constituent use values and the integration premium or discount arising from the interaction between uses, an analysis addressed in detail at the relevant investment and feasibility nodes referenced below.

Scope & Boundaries

This node covers:

  • Classification of mixed-use development as a distinct property category
  • The structure of the mixed-use sub-series and its two subordinate classifications
  • Vertical and horizontal integration models applicable to mixed-use development
  • Strata and ownership structuring considerations specific to mixed-tenure, mixed-use buildings

This node does not cover:

  • Integrated residential and retail developments → refer to Node 31710
  • Transit-oriented development → refer to Node 31720
  • Detailed strata governance and owners corporation administration → refer to Node 34310
  • Commercial lease structuring for a specific retail or office component → refer to Node 34210
Scope Note

A development comprising a single dominant use with incidental ancillary floorspace of a different use, such as a small ground-floor convenience tenancy within an otherwise wholly residential building, is not classified as mixed-use for the purposes of this node unless the ancillary use represents a material proportion of total floorspace or income.

Key Concepts

Mixed-Use Development
A development combining two or more distinct land use types within a single building or integrated site, with each use typically generating its own income stream and subject to its own regulatory and building code requirements. Classification requires that each use represent a material proportion of the development’s total floorspace or income.
Vertical Integration
A mixed-use configuration in which different uses are stacked within a single building, most commonly retail or commercial floorspace at lower levels with residential floorspace above. Vertical integration requires careful management of structural transfer, fire separation and servicing between use classes.
Horizontal Integration
A mixed-use configuration in which different uses are arranged across separate buildings or precincts within a single integrated site or master plan, sharing common infrastructure, access and public realm rather than a single building envelope.
Cross-Subsidisation Between Uses
A feasibility dynamic in which the financial performance of one use within a mixed-use development supports the viability of another, such as where a higher-value residential component supports the inclusion of below-market or specialised retail or community floorspace within the same development.

Regulatory & Legal Framework

  • State planning legislation and local planning schemes
    State Planning Departments and Local Councils
    Establishes mixed-use zoning categories and the permissible combinations, density and built form controls applicable to mixed-use development.
  • National Construction Code
    Australian Building Codes Board
    Sets fire separation, structural and servicing requirements applicable to buildings combining different building classifications, such as Class 2 residential and Class 6 retail floorspace.
  • State strata and community title legislation
    State land registries and strata regulatory authorities
    Governs the subdivision, lot entitlement and owners corporation structure applicable to mixed-tenure, mixed-use buildings.
  • State retail and commercial leasing legislation
    State fair trading or small business regulatory authorities
    Applies to the leasing of retail and commercial components within a mixed-use development, including minimum lease term and disclosure requirements.
