Ready-to-build Granny Flat Designs

The right granny flat should feel easy to choose. It should also feel right for your property and your plans.


The Castle Collection is designed for families, investors, and property owners in Port Macquarie who want a smarter way to build. It suits people who want a streamlined package, a clear process, and a design that feels more refined than a basic backyard box.


Many clients do not want to start from scratch with a custom design. They also want help understanding approvals, layout options, and what will work best on their block. Just as importantly, they want confidence that the finished granny flat will support their long-term goals.



The Castle Collection solves that problem with a curated range of standard granny flat floor plans and finishes. Each design includes practical layouts, elevated finishes, and a guided selection process. These homes are best suited to level sites and can be adapted to suit orientation, privacy, and site conditions where needed.

All-in-One Package Simplicity

The Castle Collection is built for clients who want a clear package and a clear path. You can move forward with more certainty of your budget.

Standard Designs with a High End Feel

These are not generic granny flats. These designs reflect the CastleCrew brand and are planned to feel like a compact home, with open-plan living, a full kitchen, a bathroom, and laundry.

Designed for Real Sites

The plans can be mirrored or adjusted to better suit sun, privacy, fencing, and neighbouring properties. That gives each layout flexibility while keeping the process efficient.

Quality Inclusions with Room to Choose

Each package includes a curated range of tiles, tapware, finishes, and colours. The result feels thoughtful, polished and offers great value.

A Showroom Experience That Helps

You can visit the office and showroom to see the finishes in person. That makes your choices easier and helps you feel more confident about the final result.

A Strong Fit for Families and Investors

The Castle Collection works well for extended family, guest accommodation, downsizers, home offices, teenage retreats, and rental income.

A Streamlined Package with Real Appeal

The Castle Collection is CastleCrew’s standardised granny flat range for Port Macquarie clients. It is ideal for people who value simplicity but still want a home that looks and feels well considered.


This collection is suited to clients who prefer a clear package with pre-selected layouts, inclusions, and upgrade options.

Our Port Macquarie granny flat designs balance quality and practicality. The layouts are made for comfortable living, strong rental appeal and a better everyday experience.



Every granny flat in the collection is designed to feel more like a compact home than a basic secondary dwelling. With smart use of space, elevated finishes and layout flexibility where needed, the result feels polished and easy to live in.

What Is Included in the Castle Collection

The Castle Collection is more than a set of plans. It is a considered package that helps you move forward with more clarity and confidence.

Standard Granny Flat Plans

The Castle Collection offers a range of pre-designed floor plans for clients who want a beautiful result without starting from scratch. Each plan is practical, refined, and created to maximise comfort and usability.

Included Finishes and Selections

All Castle Collection granny flats share the same core inclusions, which gives you consistency across the range. You can choose from a curated selection of tiles, tapware, colours, and finishes that create a cohesive look.

Upgrade Options and Add-Ons

There is room to personalise your package with a selection of upgrades and add-ons. Options may include alternate finishes, lighting choices, split-system air conditioning, decks, driveways, and privacy screens.

Flexible Layout Adjustments

The layouts can be mirrored or adjusted to better suit your block. This helps with privacy, sun orientation, fencing, and neighbouring properties while keeping the efficiency of a standardised design.

How the Process Works

Building a granny flat should feel straightforward. Our process is designed to guide you clearly from first enquiry through to project preparation.

1

Get in Touch

Start by contacting our team by phone, email, or enquiry form. We will talk through your block, your goals, and the style of granny flat you are considering.

2

Site Inspection with Matt

The next step is a site inspection to assess suitability. We review dimensions, orientation, and any site-specific factors that may shape the project.

3

Meet Mel at the Office

In the office, you can explore The Castle Collection and compare floor plans. This is where we help you identify the design that best suits your land and your needs.

4

Pick and Mix Your Features

Once you have chosen a direction, you can personalise the package. Select your roof design, façade style, and any additions such as decks, driveways, or privacy screens.

5

Concept Plans and Documentation

We then prepare concept plans and begin the required approval documentation. This helps move your project toward the next stage with clarity.

6

Finalise Your Selections

While approvals are underway, you can complete your selections. Choose from the included range of paint colours, tiles, tapware, and any upgrade items you would like to add.

7

project Preparation

Once approvals and selections are in place, the project moves into preparation for construction. From here, everything is lined up for the build to begin.
