WHO IS THIS FOR?
Designed for Value.
Built for Life.
Whether you are downsizing to age in place or subdividing to create a new income stream, our designs deliver the perfect balance of flexibility, quality, and long-term equity.
A Strategic Win-Win
For Homeowners wanting to add a granny flat or secondary dwelling: Release equity and future-proof your lifestyle while staying on the property you love - in total comfort and style.
For Families needing a second home: Provide a high-quality, architect-designed home for the next generation within well-established communities.
For Developers & Savvy Investors: Maximize your ROI by selling subdivided land as "Ready-to-Build" packages, significantly reducing sales cycles and project risk. Or subdivide to provide new housing with the ability to negative gear.
Unlock your land’s potential with Architect-led design, streamlined for the 2026 Planning Reforms.
Expandabode creates high-performance, bespoke secondary dwellings tailored to your site and vision. Using our "Pre-Architected" framework, we navigate Victoria's new "Deemed-to-Comply" pathways to get you from concept to construction faster than ever before.
Whether it’s a modern garden studio, granny flat or a complex dual-occupancy project, we deliver the sophistication of custom architecture without the premium price tag. Build smarter, move in sooner, and create a space that’s built to last.
WHAT IS EXPANDABODE?
Architect-designed secondary dwellings, fast-tracked for today’s property landscape.
Expandabode is an architect-led initiative by Willow Architecture + Design. Led by Lyndal Williams (Reg. Architect ARBV), we bring over 30 years of residential expertise to Victoria’s Small Secondary Dwelling (SSD) and Dual Occupancy market.
Expandabode is your strategic response to Victoria’s evolving planning reforms. We provide high-performance, pre-architected dwellings designed to maximise land value without the traditional custom-build delays.
Our process moves you from concept to approval faster by using models that are already optimised for 2026 compliance and cost-effective construction. Explore our range of builder-ready solutions below -each designed to be aesthetically striking, highly functional, unique and ready to stand the test of time.
