Granny Flats & Affordable Housing

Plan Vision has been designing projects just like yours since 1994. We have provided plans and organised approvals for over 3000 projects and cover the Newcastle, Lake Macquarie, Maitland, Cessnock, Port Stephens, Central Coast and Northern Sydney Suburbs areas.

We can help you with your granny flat or affordable housing project by providing advice, drafting the design, providing detailed, professional plans, and organising other relevant consultants as well as Council or certifier approval. You are then free to organise quotes with builders and chose the right one for you.

Please fill out the form below or give us a call to organise a time for a free, no-obligation quote and advice. Our friendly team will be happy to hear from you.

Note: our quote covers the design process, plans and through to Council or Certifier approval. We do not provide quotes for the construction cost, this can be provided by your builder. Our final plans contain all the details your builder requires for an accurate quote. 


  • What is the general process for my project?

    Every granny flat or affordable housing project is different depending on the design, location, property issues, materials, Council requirements etc. However generally the process for plan design and preparation plus approval is as follows:

    1. Free initial consultation and quoting
    2. Survey organised if required
    3. Design meeting
    4. First issue plans released
    5. Plan amendments and/or consultation input as required (eg arborist report, BASIX assessment etc)
    6. Development Application (DA) submission to Council
    7. DA Approval 
    8. Drafting of engineering plans and organise any Council DA requirements if applicable
    9. Construction Certificate (CC) application through Council or Private Certifier
    10. CC Approval

    Your builder will generally take over from here however we’re always happy to help or answer questions if required.

  • What do I need to do?

    Plan Vision will prepare your plans and other documentation to Council and/or the certifiers’ requirements. So all you really need to do is make sure you are happy with the design, and we will do everything else. We will prompt you when relevant to sign forms and make payments during the process.

  • How much will it cost?

    Prices vary depending on the type and size of your dwelling, and is different for every project. Some guides on Plan Vision pricing are outlined below though, for reference:

    • Detached granny flat/secondary dwelling – start at $2,000 plus GST
    • Attached granny flat/secondary dwelling – start at $2,500 plus GST

    All the above costs do not include payments or documents for outside consultants such as Council Fees, Water Authority Fees, Engineer's Certification, Bushfire Reports, Arborist Reports etc, which are quoted on each individual job depending on whether they are required.

  • What happens if I don't know whether particular issues affect my property?

    You don’t need to know these up front. We will work them out for you and let you know what is required.

  • What do I need to know before starting?

    If you know exactly how you’d like the design to look it’s helpful if you can provide a sketch or list of requirements. If you’re not sure of the details just yet we can sketch up some ideas for you to look at and comment on. Either way is fine! We will work with you throughout the process to provide a design you love but still complies with the relevant Council and Building codes.

  • What other projects have you completed? Do you have examples of your work?

    We have completed over 3000 projects in the Newcastle, Lake Macquarie, Maitland, Port Stephens, Central Coast and Northern Suburb areas since 1994.
