Why a Granny Flat Is a Smart Choice for Baldivis Families? 

For many property owners, a granny flat is not simply about adding another structure. It is about creating a property that better supports changing lifestyle needs. 

LEARN MORE ABOUT US →
  • Room for Loved Ones Without Sacrificing Independence

    A granny flat provides parents, adult children, or extended family members with their own space while allowing everyone to remain nearby. That added level of independence can make everyday life more enjoyable for the entire household. 

  • Making Better Use of Your Land

    Rather than allowing valuable backyard space to sit unused, you can transform it into practical accommodation with a defined purpose. A well-planned design helps the property feel more useful without feeling overcrowded. 

  • Greater Adaptability for the Future

    A space initially used for guests may later serve as a home office, downsizer accommodation, or a place for a young adult preparing for the next stage of life. The greatest benefit is having flexibility as circumstances evolve. 

  • Lifestyle and Rental Opportunities

    Current WA ancillary dwelling reforms encourage greater housing variety and permit compliant dwellings of up to 70 square metres to be occupied by relatives, friends, or tenants. This provides Baldivis homeowners with more flexibility and potential income opportunities than previous regulations. 

  • A Sensible Option Instead of Relocating

    If you enjoy your neighborhood, community, and daily routine, relocating may not be the ideal solution. A granny flat can offer a practical answer to space limitations while allowing you to remain close to the people and places that matter most. 

Granny Flat Designs Created for Everyday Baldivis Living 


Life in Baldivis varies from one household to another. Some families need additional accommodation, others want a dedicated work-from-home area, while some require versatile guest space. With Baldivis offering established residential areas, convenient amenities, and access to parks and coastal attractions, the most effective designs are those that work well in daily life rather than simply looking appealing on paper. 



From local parks and family-friendly communities to nearby coastal destinations and surrounding growth areas, Baldivis provides an ideal setting where additional accommodation can serve multiple purposes, whether that involves housing family members, welcoming guests, or creating a flexible space for work and everyday activities.

  • Standalone Granny Flats

    Separate granny flat designs are often preferred when privacy is important. They provide clear separation from the primary residence and can be ideal for long-term family accommodation, guests, or rental arrangements. 

  • Studio-Style Designs

    A studio granny flat is well suited to homeowners seeking a smaller footprint with open-plan functionality. These layouts work well for a single occupant, visiting guests, or as a peaceful retreat and workspace. 

  • 1-Bedroom Layouts

    A 1-bedroom design provides a practical balance between comfort and efficiency. It offers enough room for everyday living and is often suitable for individuals, couples, senior relatives, or renters. 

  • 2-Bedroom Granny Flat Designs

    For homeowners seeking additional versatility, a 2 bedroom granny flat can accommodate small families, shared living arrangements, or a combination of guest room and study. These layouts are frequently selected for long-term functionality. 

  • 3-Bedroom and Multi-Purpose Layouts

    When site conditions, design requirements, and approvals allow, larger floor plans with multiple rooms may be considered. The priority is ensuring the layout remains comfortable, compliant, and functional rather than overcrowding the available space. 

  • Dedicated Guest Accommodation

    In a growing community such as Baldivis, having separate guest accommodation can be extremely useful. Whether relatives visit often or you simply want a private space for visitors, a granny flat offers added comfort and privacy without affecting the main residence. 

  • Home Offices and Flexible Spaces

Understanding Granny Flat Requirements in Baldivis 

Questions about approvals are often one of the main reasons homeowners postpone their project, which is why it is important to understand the requirements clearly. 

LEARN MORE ABOUT US →
  • A Granny Flat Is Commonly Classified as an Ancillary Dwelling

    • In WA, a granny flat is generally referred to as an ancillary dwelling, meaning a self-contained residence located on the same lot as the primary home. It can be connected to the existing house, incorporated into it, or built as a separate structure. 
  • The 70m² Requirement Is Important

    • Under current WA planning reforms, compliant ancillary dwellings up to 70 square metres may be constructed on residential lots of any size without planning approval, provided the design satisfies applicable deemed-to-comply standards, including setbacks and other site requirements. However, it is advisable to confirm any site-specific overlays with the City of Baldivis. 
  • Planning Approval and Building Permits Serve Different Purposes

    • Even when planning approval is not needed, a building permit must still be obtained before construction can commence. The WA Government also advises that local councils assess building applications and can provide guidance regarding any local requirements that remain applicable. 
  • Property-Specific Factors Must Still Be Considered

    • Setbacks, site coverage, building height, privacy, access, utilities, and local planning controls continue to play an important role. The City of Baldivis notes that development approval differs from a building application and is necessary for development that is not exempt under the Local Planning Scheme and regulations. 
  • Baldivis Building Services Oversees Local Permit Processes

    • The City of Baldivis Building Services department provides building application forms online and serves as the local authority for building approvals and compliance matters. This gives homeowners a reliable local point of contact while the builder coordinates the preparation of required documentation. 
  • Professional Assistance Simplifies the Documentation Process

    Working with a builder who assists with design concepts, documentation, compliance reviews, and application submissions can save valuable time and help avoid errors. The aim is not to complicate the process with regulations but to ensure the proposed design is properly assessed before construction begins. 

All granny flats include full plans, contour survey, repeg, standard engineer's site inspection and detail for vacant A-Class sand sites, with water, sewer, electrical, and standard gas run-ins. Water and power run-in allowance is up to 15m.



Full specifications available on request. Conditions apply as per contract.

Six Simple Stages From Planning to Project Completion 

Having a structured process helps you manage expectations, organize your budget, understand timelines, and stay informed throughout the journey. 

Step 1: Property Assessment and Discovery Meeting 

The process begins with gaining a clear understanding of your objectives, land characteristics, and intended use of the space. During this discussion, we explore who will occupy the granny flat, your preferred level of finish, and any initial considerations regarding budget, site access, or approval requirements. 

Step 2: Concept Planning and Layout Assessment 

After the project brief is established, the design concept is developed into a floor plan suited to your property. The focus at this stage is creating the right balance of functionality, comfort, privacy, and compliance before progressing further. 

Step 3: Preliminary Pricing 

Our team will provide an initial estimate covering the anticipated scope of work, inclusions, and projected expenses. A detailed estimate allows you to assess your options clearly without being overwhelmed by excessive information. 

Step 4: Documentation and Approval Phase 

This stage focuses on planning and preparation. Drawings, paperwork, approvals, and construction readiness are coordinated here to help the project progress smoothly into the building phase. 

Step 5: Ongoing Build Progress Reports 

Once construction is underway, consistent updates keep you informed about progress, on-site activity, and upcoming milestones. This ensures transparency and provides a better understanding of how the project is advancing. 

Step 6: Final Inspection and Project Handover 

The last phase involves final reviews, a complete walkthrough, and formal handover. At this point, your new granny flat is finished, fully functional, and ready for occupancy.

Important Information About Granny Flat Regulations in Baldivis 

Approval-related concerns often cause homeowners to delay moving forward, so understanding the process can make planning much easier. 


  • A Granny Flat Is Generally Considered an Ancillary Dwelling

    Across WA, a granny flat is typically classified as an ancillary dwelling, which is a self-contained living space situated on the same property as the main residence. It may be attached, integrated, or completely separate from the existing dwelling. 

  • The 70m² Size Allowance Matters

    Current WA planning legislation permits compliant ancillary dwellings of up to 70 square metres on residential properties of any size without planning approval, provided all relevant deemed-to-comply provisions are met, including setbacks and site-specific requirements. It remains advisable to check with the City of Baldivis regarding any overlays affecting your property. 

  • Planning Consent and Building Approval Are Different Requirements

    Even if planning consent is not necessary, construction cannot begin without a valid building permit. The WA Government also explains that local governments assess building applications and can advise property owners on any additional local obligations. 

  • Site Requirements Still Need Assessment

    Factors such as setbacks, site coverage, height restrictions, privacy considerations, access, utilities, and local planning controls remain relevant. The City of Baldivis advises that development approval is separate from a building permit application and may be required where exemptions do not apply under planning regulations. 

  • Baldivis Building Services Manages Local Approval Pathways

    The Building Services team at the City of Baldivis makes application forms available online and acts as the local contact for approval and compliance matters. This provides homeowners with a clear local resource while builders handle the practical aspects of document preparation. 

  • Guidance With Applications Can Save Time

    A builder that provides support with concept plans, documentation, compliance assessments, and application submissions can help streamline the process and minimize errors. The objective is to ensure the proposal is reviewed correctly before construction proceeds. 

  • Home Offices and Flexible Spaces
