About Us
Granny Flat Builders Sydney One Team From Start to Finish
Smarter homes start with smarter use of land.
Across Sydney, thousands of properties have backyards sitting idle while housing pressure continues to build. GrannyFlow exists to close that gap. We are a licensed NSW granny flat builder that handles the full scope of each project site assessment, architectural design, council approval and construction through a single coordinated team rather than a patchwork of separate contractors.
GrannyFlow is the building platform of Aloha Homes Pty Ltd, a licensed NSW construction company with direct experience in residential builds including granny flats, knockdown rebuilds, and duplexes. We work with homeowners and investors across all Sydney, providing a streamlined building platform that combines site assessment, design coordination, approvals, and licensed construction into one integrated system. GrannyFlow is not a lead generation website or third-party referral service — clients deal directly with a licensed NSW builder.

Granny Flat Range
Granny Flat Designs for
Every Block and Budget
Every GrannyFlow design prioritises practical layouts, natural airflow and materials that perform well across Sydney’s climate. Whether you need a compact one-bedroom rental property or a spacious three-bedroom family home, each design is engineered around real site conditions — not just rendered to look good in a brochure.
Custom Design
Unusual Block? Specific Requirements? That Is Where We Start.
Many Sydney properties come with narrow access, steep slopes or tight setbacks that standard floor plans cannot accommodate. GrannyFlow designs purpose-built granny flats around these challenges — including wheelchair-accessible layouts, energy-efficient builds and smart home integrations.
If your property falls outside a standard template, our team is set up to handle it.
