A Local Architect’s Guide to Permits and Subdivisions

When it comes to building, renovating, or completing a subdivision project in Victoria, the process can feel overwhelming. Permits, drawings, council requirements—it can be hard to know where to start. That’s where working with a local architect makes all the difference. 

At SON Architects, we’ve helped countless homeowners, developers, and investors bring their visions to life by guiding them through the planning permit process. One of the most important parts of this journey is preparing accurate architectural planning drawings. These drawings aren’t just technical paperwork—they’re your project’s ticket to approval, and the foundation for a smooth construction phase. 

What Are Planning Drawings and Why Do You Need Them?

Planning drawings are detailed architectural documents submitted to council as part of a planning permit application. They show your design intent, how the building will sit on the site, and how it complies with zoning, overlays, and local planning rules.


For example, if you’re planning a subdivision, your planning drawings will need to illustrate:

  •  Existing and proposed lot boundaries
  •  Vehicle access and parking layouts
  •  Site setbacks and private open space
  •  Shadows, privacy treatments, and overlooking measures
  •  How the design integrates with surrounding properties


Without these drawings, council simply won’t be able to assess or approve your proposal.

SON Architects is more than capable to support you with drawings and documentation to support your p

Planning Permit vs Building Permit

Planning Permit: Land Use, Context, and Neighbourhood Impact

Building Permit: Safety, Structural Integrity, and Technical Standards

Building Permit: Safety, Structural Integrity, and Technical Standards

A Planning Permit is written approval from your local municipal council allowing a specific use or development on a particular piece of land.


Local councils assess planning applications against the Victoria Planning Provisions (VPP) and their specific municipal planning scheme. This stage is not concerned with how the building is physically bolted together; instead, it evaluates how the proposal interacts with its surroundings.


Key considerations include:

  • Zoning & Overlays: Determining what is permitted within your zone (e.g., Neighbourhood Residential, General Residential, Mixed Use) and complying with specific overlays (such as Heritage Overlays, Special Building Overlays for flood risk, or Vegetation Protection Overlays).
  • Neighbourhood Character & Amenity: Reviewing building heights, boundary setbacks, overlooking/privacy impacts, overshadowing of private open space, and streetscape integration.
  • Environmental & Strategic Impact: Assessing tree removal, site permeability, vehicle access, and stormwater retention.


Rule of thumb: A planning permit grants legal permission to alter the use, density, or form of a site within the community context.

A Building Permit is formal approval issued by a Registered Building Surveyor (RBS) confirming that the proposed construction documentation satisfies technical, safety, and health regulations.


A building permit ensures the structure will be safe for occupants and durable over time. You cannot obtain a building permit that contradicts an endorsed planning permit.


Key considerations include:

  • Structural Engineering: Verification of footings, framing, load-bearing walls, slab designs, and steelwork calculations.
  • Life Safety & Compliance: Fire separation walls, smoke alarms, emergency egress, bushfire attack level (BAL) compliance, and balustrade heights.
  • Health & Amenity: Room ceiling heights, ventilation, natural light, damp-proofing, and waterproofing standards.
  • Energy Efficiency: Compliance with minimum Nationwide House Energy Rating Scheme (NatHERS) thermal performance and 7-star energy standards under the NCC.


Rule of thumb: A building permit ensures the approved architectural concept can be safely and legally executed by your builder.

The Subdivision Angle: Why Accurate Drawings Are Key

Subdivision projects—whether you’re creating two townhouses on one block, splitting a backyard lot, or delivering a medium-density development—always require detailed planning documentation.


A local architect with subdivision experience can:

- Design layouts that maximise yield without compromising liveability

- Ensure compliance with ResCode and local council subdivision guidelines

- Incorporate efficient vehicle access, parking, and open space design

- Create sustainable, future-proof solutions that appeal to buyers or tenants


Subdivision is one of the most effective ways to unlock land value in Victoria, but it’s also one of the most scrutinised. Council will carefully review how your project fits into the existing neighbourhood character. Without high-quality architectural drawings, your application risks rejection or lengthy delays.

Why You Should Work With an Architect For Permit Application

The permit system in Victoria is complex, and requirements vary greatly between councils. A local architect not only understands the technical side of preparing drawings but also has the advantage of working regularly with specific councils, planners, and assessors.


With SON Architects, you will be benefit from:

- Local Knowledge: We’re familiar with council requirements across Melbourne and regional Victoria.

- Subdivision Expertise: We know how to balance yield with compliance and livability.

- Streamlined Process: From concept to approval, we handle the details so you don’t have to.

- Future-Proof Design: Sustainable and cost-effective solutions tailored to your site and budget.

 

Subdivision, Planning, and Beyond

Securing your planning permit is just the beginning. Once your drawings are endorsed, we guide you through the transition into the building permit stage, ensuring your project stays compliant and efficient. For subdivision projects, we also collaborate with surveyors and town planners to deliver a coordinated outcome that maximises land value.

We work hard to ensure the process is seamless for you at SON Architects!

Frequently Asked Questions

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

A planning permit assesses how your proposed subdivision or development impacts the surrounding neighbourhood, infrastructure, and environment. Your local council evaluates key factors—such as zoning rules, minimum garden area requirements, boundary setbacks, overlooking, and site coverage—to ensure the project complies with the local planning scheme before any physical division or construction is approved. 


Planning Permit: Grants permission to subdivide land or build multiple dwellings based on zoning, land use, and neighbourhood character. It is issued by the local council.


Building Permit: Focuses on execution, safety, and structural integrity. Issued by a Registered Building Surveyor, it certifies that architectural and engineering plans comply with the Building Act 1993, Building Regulations 2018, and the National Construction Code (NCC).


In almost all subdivision and multi-unit developments in Victoria, both permits are mandatory.


Suitability depends on several critical site and regulatory constraints, including:

  • Zoning & Overlays: Specific planning zones (e.g., NRZ, GRZ, RGZ) and overlays (such as Heritage, Flooding/SBO, Bushfire/BMO, or Significant Landscape Overlays) that impose development restrictions.
  • Site Dimensions: Frontage width, overall site depth, and total land area.
  • Access & Vehicle Crossovers: Adequate space for shared driveways, car parking, and turning circles.
  • Easements & Underground Services: The location of stormwater, sewer, electricity, and telecommunications infrastructure.


  1. Feasibility & Concept Design: Assessing zoning, overlays, and site potential.
  2. Town Planning Documentation: Preparing detailed site context analyses, floor plans, elevations, shadow diagrams, and planning reports.
  3. Council Application & Endorsement: Submitting for planning approval and addressing council/neighbour queries.
  4. Plan of Subdivision & Certification: Engaging a licensed land surveyor to prepare the formal plan for council certification and utility authority consents (SPEAR process).
  5. Statement of Compliance & Title Registration: Fulfilling all permit conditions and financial contributions to receive a Statement of Compliance, allowing Land Use Victoria to issue new individual titles.


Navigating council planning schemes and technical building codes can be complex. A local architect:

  • Conducts thorough feasibility assessments to identify opportunities and constraints early.
  • Designs yield-optimised layouts that balance aesthetic quality, liveability, and strict regulatory compliance.
  • Coordinates specialist consultants (e.g., land surveyors, structural engineers, arborists, and traffic engineers).
  • Manages council submissions and requests for further information (RFIs), reducing delays and avoiding costly redesigns.
