Clause 58 Apartment Design Standards: Melbourne Guide

Overview: How Clause 58 Shapes Apartment Development in Melbourne

If you’re planning a five-storey or taller apartment development anywhere in Melbourne’s Eastern Suburbs, Clause 58 of the Victorian Planning Provisions is the single most important document governing your project’s design. Unlike the more familiar ResCode framework that applies to smaller residential developments, Clause 58 — formally known as the Apartment Developments provisions — sets out a comprehensive suite of design standards specifically calibrated for multi-storey apartment buildings. Getting across these requirements early could be the difference between a smooth planning permit pathway and a costly, time-consuming objection or VCAT hearing.

For developers working across the City of Whitehorse, City of Boroondara, Manningham City Council, City of Monash, City of Knox, and Maroondah City Council, Clause 58 applies consistently as a state-level provision — but how each Responsible Authority interprets and applies it can vary considerably. Understanding both the baseline standards and the local nuances is essential for any developer seeking to maximise yield, manage risk, and move efficiently through the planning permit process.

This guide walks through the core Clause 58 design standards, outlines what each standard means in practical terms for your development, highlights common areas where applications encounter difficulty, and gives you a clear picture of what a well-prepared submission looks like.

What Is Clause 58 and When Does It Apply?

Clause 58 was introduced into the Victorian Planning Provisions as part of the Better Apartments Design Standards reforms, as a broader effort to lift the standard of apartment design across Melbourne. It replaced earlier, less prescriptive guidance and introduced mandatory and discretionary standards covering everything from apartment size and natural light through to building setbacks, communal open space, and waste management.

The clause applies to any residential building of five or more storeys — measured from natural ground level — that contains dwellings. This means it captures the vast majority of medium-to-high-density apartment projects that developers are pursuing across Melbourne’s middle-ring suburbs. If your project sits at four storeys or below, ResCode (Clause 55) is the relevant framework. At five storeys and above, Clause 58 takes over entirely.

It’s worth noting that Clause 58 contains both mandatory standards (which cannot be varied regardless of circumstances) and discretionary standards (which a Responsible Authority may vary if a design response demonstrates an equivalent or superior outcome). Understanding which standards fall into which category is critical for project feasibility assessment and design development. For a broader overview of how Victorian planning and building regulation is structured, see our guide to Victorian building regulations.

Core Design Standards: The Key Clause 58 Requirements

Apartment Size and Layout

One of the most developer-relevant aspects of Clause 58 is the mandatory minimum apartment sizes. These are not discretionary — they cannot be varied by the Responsible Authority or VCAT. The minimum internal floor areas are:

• Studio apartments: 37 square metres minimum
• One-bedroom apartments: 50 square metres minimum
• Two-bedroom apartments: 65 square metres minimum
• Three-bedroom apartments: 90 square metres minimum

These figures represent net internal area, measured from the internal face of external walls and excluding balconies, car parking, storage, and common areas. For developers accustomed to working with gross floor area figures, this distinction matters significantly when modelling yield. A two-bedroom apartment that measures 65 square metres internally may have a gross footprint of 75–80 square metres once wall thicknesses, balcony connections, and circulation are factored in.

Storage requirements are also mandatory under Clause 58. Each apartment must include a minimum storage volume: 6 cubic metres for one-bedroom apartments, 8 cubic metres for two-bedroom apartments, and 10 cubic metres for three or more bedrooms. At least 50% of this storage must be located within the apartment itself. These figures directly affect your floor plate design and should be incorporated from the earliest indicative assessment stage.

Natural Light and Ventilation

Clause 58 sets mandatory requirements for natural light access to habitable rooms. Every habitable room — including bedrooms, living areas, and studies — must receive direct natural light through a window or glazed door with a minimum area equal to 10% of the floor area of that room. This is a mandatory standard and cannot be varied.

The ventilation requirements are equally prescriptive. Each habitable room must have openable windows or doors with a minimum area equal to 5% of the room’s floor area. Additionally, Clause 58 places restrictions on single-aspect apartments — those with windows on only one side of the building. Single-aspect apartments are permitted, but they must not face south (in the southern hemisphere context) unless the design can demonstrate adequate solar access through other means. In practice, this means south-facing single-aspect apartments are extremely difficult to approve and should generally be avoided in your floor plate design.

For developers working in areas like Box Hill (City of Whitehorse) or Ringwood (Maroondah City Council), where high-density precincts are actively encouraged, these light and ventilation standards have a direct bearing on how efficiently you can stack apartments on a constrained site. Engaging an architect with detailed knowledge of Clause 58 early in the design process — before you’ve committed to a floor plate — can save significant redesign costs later.

Balconies and Private Open Space

Every apartment in a Clause 58 development must include private open space in the form of a balcony or terrace. The minimum balcony dimensions are:

• Studio and one-bedroom apartments: 8 square metres, minimum depth of 1.6 metres
• Two-bedroom apartments: 10 square metres, minimum depth of 1.6 metres
• Three or more bedroom apartments: 12 square metres, minimum depth of 2.4 metres

These are mandatory standards. The balcony must be directly accessible from a habitable room — typically the living area — and must be usable, meaning it cannot be so narrow or awkwardly shaped as to be functionally unusable. Responsible Authorities across Melbourne’s Eastern Suburbs have become increasingly attentive to balcony design quality, and applications that include technically compliant but poorly designed balconies may still attract objections or requests for redesign.

Ground-floor apartments may substitute a private courtyard or garden area for a balcony, provided the area meets the minimum size requirements. This can be a useful design tool for activating ground-floor frontages while still meeting the private open space standard.

Communal Open Space

Clause 58 requires that apartment developments include communal open space — shared outdoor areas available to all residents. The minimum requirement is 10% of the site area, with a minimum area of 20 square metres and a minimum dimension of 3 metres. This space must be located at ground level or on a podium, and must receive a minimum of two hours of direct sunlight between 9am and 3pm on 22 June (the winter solstice).

For developers working on smaller infill sites — a common scenario in suburbs like Camberwell (City of Boroondara) or Doncaster (Manningham City Council) — the communal open space requirement can place real pressure on site coverage and yield. On a 1,000 square metre site, for example, you may need to set aside at least 100 square metres of communal open space, which needs to be carefully integrated into the building design rather than treated as an afterthought.

Rooftop communal spaces can count toward this requirement in some circumstances, but they must still meet the sunlight access standard, which can be difficult to achieve on a north-facing rooftop that is overshadowed by the building itself. Early shadow analysis is strongly recommended before committing to a rooftop communal space strategy.

Building Setbacks and Separation

Clause 58 includes both mandatory and discretionary standards relating to building setbacks and separation between buildings. The mandatory standard requires a minimum 6-metre separation between habitable room windows on facing walls within the same development. This is a non-negotiable requirement and has significant implications for dual-tower or split-building configurations on larger sites.

Setbacks from property boundaries are largely discretionary under Clause 58, meaning the Responsible Authority has flexibility to accept variations where the design response is well-justified. However, each council across Melbourne’s Eastern Suburbs applies its own overlay controls and local policy context that effectively constrain this flexibility. The City of Boroondara, for instance, applies Design and Development Overlays across significant portions of its activity centres that prescribe specific setback requirements above and beyond the Clause 58 baseline. Similarly, the City of Whitehorse has specific built form guidelines for the Box Hill Metropolitan Activity Centre that developers must navigate alongside Clause 58.

Council-Specific Variations Across Melbourne’s Eastern Suburbs

While Clause 58 is a state-level provision applied consistently across Victoria, the planning scheme context in which it operates varies significantly between councils. Developers need to understand both the Clause 58 standards and the local overlay and policy framework that shapes how those standards are applied.

In the City of Whitehorse, the Box Hill Activity Centre is subject to a specific Structure Plan and Design and Development Overlay that prescribes height limits, setbacks, and active frontage requirements. Clause 58 applications in Box Hill must satisfy both the state-level design standards and these local controls simultaneously.

The City of Boroondara is known for a particularly thorough assessment process, with a strong emphasis on neighbourhood character, heritage context, and interface with lower-density residential areas. Applications for five-storey-plus developments in suburbs like Camberwell, Hawthorn, or Kew will typically attract significant scrutiny around upper-level setbacks and the transition to adjoining residential zones.

In Manningham City Council, the Doncaster Hill Activity Centre has its own Structure Plan that guides apartment development, with specific provisions around height, setbacks, and public realm activation. Clause 58 applications in this precinct need to be read alongside the Doncaster Hill guidelines.

City of Monash has been actively encouraging higher-density development around Oakleigh and Glen Waverley, and the council’s planning scheme includes provisions that may facilitate more flexible interpretation of discretionary Clause 58 standards in these activity centres — provided the design response is well-articulated.

Mandatory vs Discretionary Standards: A Practical Framework

One of the most important distinctions for developers to understand is which Clause 58 standards are mandatory and which are discretionary. This distinction directly affects your design flexibility and your ability to respond to site-specific constraints.

Mandatory standards (cannot be varied) include:

• Minimum apartment sizes
• Minimum storage volumes
• Natural light to habitable rooms — 10% window-to-floor-area ratio
• Ventilation — 5% openable window-to-floor-area ratio
• Minimum balcony sizes and dimensions
• Minimum 6-metre separation between habitable room windows

Discretionary standards (may be varied with justification) include:

• Building setbacks from property boundaries
• Communal open space location and configuration (in part)
• Landscaping and deep soil provisions
• Waste and recycling facilities
• Car parking layout and access

When seeking a variation to a discretionary standard, the planning permit application must include a written justification demonstrating that the proposed design achieves an equivalent or superior outcome to the standard. This justification should be prepared by a registered architect and supported by technical analysis — shadow diagrams, wind studies, acoustic reports — as appropriate. For guidance on what documentation is required, see our overview of architectural planning drawings for planning permit applications.

Practical Tips for Clause 58 Compliance

Based on SQM Architects’ experience working across Melbourne’s Eastern Suburbs, the following practical guidance may help developers navigate Clause 58 more effectively.

Conduct a Clause 58 Indicative Assessment Before Purchasing

The mandatory standards under Clause 58 — particularly minimum apartment sizes and balcony dimensions — have a direct and significant impact on achievable yield. Before committing to a site, it is worth commissioning a preliminary Clause 58 indicative assessment to understand how many apartments of each type may realistically be achievable on the site while meeting all mandatory standards. This assessment should also account for the communal open space requirement and any applicable overlay controls.

Engage Your Architect Before Lodging a Planning Permit Application

Clause 58 applications require a comprehensive set of documentation, including a design response, shadow diagrams, floor plans, elevations, and a written assessment against each applicable standard. Applications that are lodged without this documentation are likely to receive a request for further information from the Responsible Authority, adding weeks or months to your planning permit timeline. Engaging a registered architect with Clause 58 experience before lodgement may help ensure your application is more complete and better prepared from the outset. SQM Architects can assist with this process — contact us to discuss your project.

Address Overlooking and Overshadowing Proactively

Two of the most common grounds for objection in Clause 58 applications are overlooking of neighbouring properties and overshadowing of communal open space or neighbouring secluded private open space. Preparing detailed shadow diagrams and overlooking analysis as part of your application — rather than waiting for these issues to be raised — demonstrates to the Responsible Authority that your design has been carefully considered and can significantly reduce the likelihood of objections.

Consider Wind Impact for Upper-Level Communal Spaces

For developments of five storeys and above, wind impact on communal open spaces and balconies can be a significant issue, particularly in exposed locations. A wind impact assessment prepared by a qualified engineer can support your application and demonstrate that proposed communal spaces will be usable and comfortable for residents.

Frequently Asked Questions

Does Clause 58 apply to mixed-use developments with apartments above ground-floor retail?

Yes. Clause 58 applies to any residential building of five or more storeys that contains dwellings, regardless of whether the ground floor or lower floors are used for non-residential purposes. The residential component of a mixed-use development must comply with all applicable Clause 58 standards.

Can a Responsible Authority vary the mandatory minimum apartment sizes under Clause 58?

No. The minimum apartment sizes specified under Clause 58 are mandatory and cannot be varied by the Responsible Authority or by VCAT. Any apartment that does not meet the minimum internal floor area for its type cannot be approved under Clause 58.

How does Clause 58 interact with Design and Development Overlays applied by councils like the City of Whitehorse or City of Boroondara?

Clause 58 and Design and Development Overlays operate concurrently. A development must satisfy both the Clause 58 standards and any applicable overlay requirements. Where the overlay imposes more restrictive requirements — for example, a lower height limit or greater setback — the more restrictive requirement generally prevails.

What documentation is required to support a Clause 58 planning permit application?

A Clause 58 application typically requires architectural drawings (floor plans, elevations, sections, and a site plan), a written design response addressing each applicable standard, shadow diagrams for 22 September and 22 June, a landscape plan, a waste management plan, and a traffic and car parking assessment. Some councils may also require a wind impact assessment, acoustic report, or urban context report depending on the site and its surroundings.

How long does a Clause 58 planning permit application typically take to assess?

Processing times vary between councils and depend on the complexity of the application, the number of objections received, and the Responsible Authority’s current workload. As a general indication, straightforward applications in Melbourne’s Eastern Suburbs may be assessed within a matter of months, while more complex applications or those that attract objections may take considerably longer. For context on recent changes to permit pathways, see our overview of the Fast-Track Planning Bill. If a decision is not made within the statutory timeframe, an applicant may apply to VCAT for a review on the basis of deemed refusal.

Can south-facing single-aspect apartments be approved under Clause 58?

South-facing single-aspect apartments face significant challenges under Clause 58 because they are unlikely to meet the natural light requirements for habitable rooms. While the standard is technically discretionary in some respects, the Responsible Authority would need to be satisfied that the design achieves an equivalent outcome to the standard — which is very difficult to demonstrate for south-facing apartments with no access to direct sunlight. In practice, south-facing single-aspect apartments should be avoided in your floor plate design.

Does Clause 58 require car parking for apartment developments?

Clause 58 itself does not specify car parking rates — these are determined by Clause 52.06 of the planning scheme and any applicable local policy. However, Clause 58 does include standards relating to the design and layout of car parking areas within apartment developments, including requirements for bicycle parking and end-of-trip facilities. The applicable car parking rates vary between councils and between activity centre locations, so it is important to check the specific requirements for your site.

Getting the Most From Clause 58 Compliance

Clause 58 is sometimes perceived by developers as a constraint on yield and design flexibility — and in some respects, the mandatory standards do impose real limits. But developers who engage with the framework early and design to its requirements from the outset tend to achieve more favourable outcomes than those who treat compliance as an afterthought. A well-designed Clause 58 development could support a stronger planning permit outcome and may be better received by the Responsible Authority and future occupants.
