The Process

At XL Built, we customise every build because no two families are the same. We work closely with your family to understand your needs and design a home that’s as practical as it is comfortable for your lifestyle.
Our design process is divided into three stages to ensure that nothing is overlooked and that all your single-storey extension ideas are fully considered.
This system is unique to XL Built and consists of:
Stage 1 – Concept Design
Stage 2 – Design Development
Stage 3 – Final Design and Documentation
Your approval is required at each stage, ensuring nothing is missed and that your ground-floor extension costs remain controlled. XL Built also offers a money-back guarantee on your home extension design, giving you creative freedom without hesitation.
Our experienced team handles all necessary permits and documentation, taking the stress off your shoulders. Throughout the process, communication is key, with multiple ways to stay connected, whether online, directly, or through our exclusive internal portal.
Your vision is our vision.
Registered with the Building Practitioner’s Board, all our builds are executed to exceed industry standards. Every project is covered by multiple insurances and does not commence without Home Owner’s Warranty insurance, Public Liability insurance, Contract Works insurance, and Work Cover.
Once your single-storey extension design is complete, our team creates a custom schedule for your build. Adhering to strict timelines, this schedule ensures the fastest possible completion for your home.
After scheduling and securing the deposit, we begin the project with any necessary demolition. Throughout each stage of the build — from the base, frame, roof cover, lock-up, internal wall lining, fixing, to completion — more than 2,000 items are assessed on our quality management checklist. Our team ensures nothing is overlooked.
Should changes be needed during the build, we offer flexibility in design while maintaining close communication with you. Our highly skilled, friendly, and respectful tradespeople are handpicked to ensure only the best work on your dream home.
Even after our work has finished, our service continues. Once you move into your dream home, we offer a three-month maintenance period to address any unforeseen defects that may arise.
As our work is executed by highly skilled tradespeople, we are confident in the quality of our craftsmanship. That’s why we provide a 10-year structural guarantee, ensuring peace of mind for the future of your home.
We offer ongoing support and are always available to help make you as comfortable as possible in your newly built home. Our service begins the moment you visit our website and extends for many years as you enjoy the perfection of your custom-built home.

What is Multigen?

Multigenerational homes are households designed to accommodate two or more generations living under one roof. Currently, more than four million Australians live in multigenerational homes, representing one in five of the population.

The benefits of multigenerational living are both financial — with shared mortgage, bills, and maintenance costs — and practical, providing peace of mind as grandparents can be cared for or assist with looking after young children.

XL Built can help transform your home into a MultiGen space, whether by adding a separate living area or building a custom new home. Professionally designed MultiGen homes consider the needs of your entire family.
