Each GrannyFlow project begins with a detailed understanding of the homeowner’s property, goals and constraints — from investment-focused one-bedroom builds to larger family homes across Sydney’s Western suburbs, Inner West and beyond
Granny Flat Construction Sydney — Everything Under One Roof
GrannyFlow is a vertically integrated granny flat building company.
That means one team, one contract and one point of accountability from the moment you enquire through to the moment you receive your keys. We coordinate and manage all stages of the project on your behalf.

Renovations & Additions
We now undertake renovations, extensions and additions to existing houses and commercial premises. Whether you are reconfiguring a kitchen, adding a second storey or extending a living area, get in touch for a complimentary consultation and quote.
Studios & Outbuildings
After something smaller than a full granny flat — or want to add a studio alongside one? From pool cabanas to garden workshops, we design and build ancillary structures to suit any brief.
Custom Design Granny Flats
Every household has a different set of priorities, site conditions and budget constraints. Our custom design service starts with a blank page and works with you to create a layout that fits your life — including tricky blocks that other builders walk away from.
Pre-Designed Granny Flat Layouts
Select from our library of one, two, three and four-bedroom floor plans, each engineered to suit a range of block shapes and budgets. Pre-designed layouts offer a faster approval timeline along with bundled upgrades and savings not available on bespoke builds.
