Why Planning Approval Is Important Before Building a New Home

Planning a new home, townhouse development, extension or second dwelling is an exciting step. You may already be thinking about the floor plan, façade, interiors, materials and lifestyle you want to create. But before those ideas can move confidently towards construction, one important question needs to be answered.

Can your project be approved?

Planning approval is one of the most important stages in any building journey because it determines whether your design responds properly to the land, the local planning scheme, neighbourhood character and council requirements.

In Victoria, planning reform has become a major topic. The Victorian Government’s Townhouse and Low-Rise Code introduced a “deemed to comply” assessment pathway to support faster decisions and greater certainty for townhouses and apartment buildings up to three storeys under Clause 55. The deemed to comply standards commenced operation on 31 March 2025.  

For homeowners, investors and developers, this is a clear reminder that good planning is not just paperwork. It is the foundation of a smoother, smarter and more successful project.

What is planning approval?

Planning approval is the process of assessing whether a proposed development is suitable for a particular site and location. It looks beyond the building itself and considers how the project fits within its surroundings.

This may include:

• Zoning
• Overlays
• Setbacks
• Building height
• Neighbourhood character
• Site coverage
• Access and parking
• Landscaping and tree canopy
• Private open space
• Overlooking and overshadowing
• Council policies and local planning controls

In Victoria, Clause 55 applies to the development of two or more dwellings on a lot and residential buildings up to and including three storeys, and a planning permit is always required for these developments in residential zones.  

This is why planning approval should be considered early, not after the design is already complete.

Why planning approval matters before you buy or design

Many people purchase land or begin designing a home without fully understanding the planning conditions attached to the site. A block may look ideal, but there can be hidden constraints that affect what can actually be built.

For example, your site may have a heritage overlay, bushfire considerations, flood risk, slope issues, access challenges or strict neighbourhood character requirements. A design that works beautifully on one site may not be suitable for another.

This is where early planning advice can save time, money and stress. When planning risks are identified early, the design can respond intelligently from the beginning instead of needing major revisions later.

Planning approval can shape the entire design

A strong design is not only about appearance. It must also work within the planning framework.

The Victorian Government has stated that the updated residential planning rules are intended to make it faster and easier to build more liveable and sustainable medium density homes, while setting standards for matters such as setbacks, tree coverage, sunlight, neighbourhood fit and amenity.  

For clients, this means a successful project needs to balance three important areas:

Your vision
The home, development or space you want to create.

The site conditions
The land, slope, orientation, access, surrounding properties and physical constraints.

The planning rules
The local requirements that determine what council may support.

When these three areas are considered together, the result is a more confident and practical design pathway.

What happens when planning is not considered early?

When planning approval is treated as an afterthought, projects can face avoidable issues.

A concept may need to be redesigned because it does not meet setback requirements. A townhouse proposal may create overlooking or overshadowing concerns. A second dwelling may not provide enough private open space. A development may not respond well to neighbourhood character. Parking, access or site coverage may become a problem.

These issues can lead to delays, extra consultant costs, redesign work, council requests for further information or uncertainty around approval.

Early planning assessment helps reduce these risks.

Why this is especially important for townhouses and low-rise developments

Townhouses, dual occupancies, small multi-unit projects and second dwelling opportunities are becoming more important across Victoria and Tasmania as homeowners and developers look for better ways to use land.

The Victorian Townhouse and Low-Rise Code is designed to provide greater certainty for townhouses and low-rise residential buildings when applications meet the required standards. These standards include matters such as street setback, building height, side and rear setbacks, site coverage, access, tree canopy and front fences.  

For property owners and developers, this creates opportunity, but it also makes quality documentation and planning-led design even more important.

A well-prepared application is not just about drawing a building. It is about demonstrating how the proposal responds to the rules, the site and the surrounding area.

How Urban Space Designers can help

At Urban Space Designers, we understand that every successful project starts with clarity.

Our Planning Assessment and Advocacy service is designed to help clients navigate planning regulations and approval processes with strategic guidance, detailed analysis and comprehensive support. Our process includes reviewing site conditions, preparing feasibility advice, aligning projects with local planning policies, preparing planning reports and liaising with councils and consultants.  

We assess your site early, identify planning risks, prepare the right documentation and help you approach council requirements with confidence.

Our team also provides architectural design and drafting, structural and civil engineering, and design coordination services, allowing clients to move through the project journey with a more integrated approach.  

The value of starting with professional advice

Before you commit to land, finalise a design or lodge an application, professional planning and design advice can help you understand:

• What may be possible on your site
• Whether your proposal is likely to need a planning permit
• Which overlays or local controls may affect the design
• How setbacks, height, access and private open space may influence the layout
• What documentation may be required
• How to improve the approval pathway before submitting to council

This gives you more confidence before making major financial and design decisions.

Planning approval is not just a hurdle. It is a strategy.

Many clients see planning approval as a barrier. In reality, it can be a valuable part of the design process.

When handled well, planning helps create better homes, smarter developments and more considered outcomes for the people who will live in and around the project.

It encourages better use of land, stronger design decisions, improved amenity and greater certainty before construction begins.
