The Steps Behind a Smooth Build

From the first conversation to final handover, CastleCrew guides you through each stage with clear support and practical advice. Our process is designed to keep your custom granny flat or tiny home moving smoothly from design to build.

1

Get in Touch

Reach out by phone, email, or through our website to discuss your ideas and goals. This is the first step in working out what type of custom granny flat or tiny home may suit your property.

2

onSite Inspection

Matt will arrange an on-site visit to discuss your plans and assess the property. This helps us understand the site before the design process begins.

3

Drafting and Site Measure

A second onsite meeting is held with the drafter. Measurements are taken, and your vision is explored in more detail, so concept plans can begin.

4

Concept Drawings and Revisions

CastleCrew presents the initial concept drawings for your review. Feedback is welcome, and refinements are made until you are happy with the layout and direction.

5

Facade and Finish Selections

Façade details and internal finishes are discussed as the design is finalised. This stage helps personalise the space and align it with your preferences or the look of the main home.

6

Approvals and Documentation

Once the concept is approved, CastleCrew prepares and issues the CDC or DA documentation for the project. This is an important step on the path to construction.

7

Selections During the Approval Stage

While approvals are being processed, you can choose colours, tiles, tapware, vanities and other finishes. This helps keep the project moving smoothly.

8

Construction and Handover

Once approvals and the Construction Certificate are in place, a start date is scheduled. A typical granny flat build takes around 12 weeks, with communication maintained throughout the construction phase.

Frequently Asked Questions

  • What’s the difference between a standard granny flat plan and a custom granny flat?

    A custom granny flat is designed specifically for your block, your needs and how you want to use the space. It allows you to adjust the layout, orientation, finishes and overall feel so it works better for your lifestyle and your property. This is especially valuable if your site has unique conditions or you want something more tailored.


    A standard plan is a pre-designed layout that has already been mapped out and approved as a proven design. It is a great option if you want something efficient and straightforward.

  • Can you design a granny flat for a small, narrow or unusual block?

    Yes. In fact, custom granny flats are often the best solution for sites that are not standard.


    Whether your block is narrow, sloping or has access limitations, a tailored design can work around these constraints. With the right planning, most sites can be optimised to make the most of the available space while still meeting council requirements.

  • Can I build a tiny home with custom upgrades?

    Yes. A smaller footprint does not mean you have to compromise on comfort or style.


    You can create a compact granny flat or tiny home with upgraded finishes, smart storage, and thoughtful design touches that make the space feel open and practical. This is a popular option for modern living, guest accommodation or downsizing.

  • What parts of the granny flat can be customised?

    Almost every aspect can be tailored to suit your needs.


    This includes the layout, façade, ceiling height, window and door openings, internal finishes, and how the indoor and outdoor areas connect. Features like decks, alfresco spaces and overall flow can also be designed to suit how you plan to use the space.


    CastleCrew works closely with you throughout this process to make sure the final design feels right both visually and practically.

  • Do you help with drafting and council approval?

    Yes. CastleCrew manages the process from the early concept stage through to approvals.


    This includes preparing drawings, coordinating documentation and guiding your project through either CDC or DA approval pathways. Having this handled as part of the service helps streamline the process and avoids unnecessary delays.

  • How long does it take to build a custom granny flat?

    Once approvals and certificates are in place, construction typically takes around 12 weeks.


    The full timeline can vary depending on the approval process and site conditions, but you will have a clear understanding of timing before construction begins.

  • Can the granny flat be designed to match my main home?

    Yes. The design can be tailored to compliment your existing home and overall streetscape.


    From façade style to colours and finishes, the goal is to create a cohesive look so the granny flat feels like a natural extension of the property rather than an afterthought.

  • Is a custom granny flat a good option for rental income or resale value?

    A well-designed granny flat can be a strong long-term investment.


    Custom designs often perform better for rental appeal because they make smarter use of space and feel more liveable. They can also add value to the overall property by improving functionality and presentation.

  • When do I choose colours, tiles, tapware and finishes?

    Selections are made while approvals are being finalised.


    This allows everything to be organised ahead of construction so there are no delays once the build begins. You will be guided through the selection process to ensure everything works together and suits your design.
