Turn your backyard into a smart income-producing home, not a headache.
GrannyFlow helps Sydney owners design and build simple, durable granny flats that feel good to live in and make sense on the spreadsheet – with builder-level detail and investor logic.
Our platform vision is simple: start with honest, small backyard homes, then grow into a network of modular, affordable spaces that help families and investors unlock fair housing, calmer cashflow and less speculation – one site at a time.
Builder clarity meets investor discipline.
GrannyFlow sits at the intersection of three worlds: real building experience, long-term value investing, and a deep respect for how people actually live day-to-day in small homes.
Numbers before emotions
We help you understand build cost drivers, realistic rent ranges and different payback scenarios – in plain language, not overwhelming spreadsheets.
Simple, durable design
No over-complicated architecture that looks great online but is painful to maintain. We prioritise light, airflow, storage and robust materials.
One honest conversation
We talk through your borrowing power, family situation and exit options – not just the build. If a granny flat doesn’t make sense for you now, we’ll say so.
Builder brain + investor brain in one place.
Many builders just quote a number and start digging. GrannyFlow begins earlier: what role does this granny flat play in your whole life and asset plan?
We look at your land conditions, planning limits, lending structure, likely rent, future add-on potential and – most importantly – the real rhythm of life for you and your family. A good project should feel calm and sustainable in daily life, not just look good in Excel.
Over time, GrannyFlow aims to grow into a living platform of repeatable, modular backyard homes – a quiet, patient alternative to pure speculation, where better housing and better numbers can actually co-exist.
