Built Around Your Property, Not Forced Into It
Local Granny Flat Builders Who Design Around Your Property
Before anything is designed, we assess your specific property carefully. From tighter Bayside blocks to larger Peninsula sites, every granny flat is designed to feel natural on the land, not forced into it.
Available Space & Layout
We assess your block size, shape, and available footprint to determine the best position and configuration for your granny flat, maximising space without compromising your main home.
Access Points & Positioning
We plan separate entry access, driveway requirements, and positioning that works practically for both occupants, ensuring your property functions well for everyone using it.
Privacy Between Dwellings
Thoughtful orientation, screening, and window placement ensure genuine privacy for both the main home and the granny flat, so both spaces feel comfortable and independent.

Every Melbourne suburb, Bayside area, and Peninsula council comes with its own planning rules. With 20+ years of local experience, we know exactly what’s required and manage the entire approval process for you.

Common Questions
Granny Flat FAQs
With 20+ years as granny flat builders in Melbourne, we’ve answered every question homeowners have.
Do I need council approval before building a granny flat?
Yes, most granny flat projects require council approval before construction begins. With 20+ years of Melbourne building experience, we manage the entire approval process for you, from initial planning permits through to final building approval, so you don’t have to navigate complex council requirements alone.
How long does it take from start to finish?
Most granny flat builds take between 10 and 16 weeks, depending on council approval timelines and design complexity. With 20+ years of Melbourne experience, we plan every project to avoid unnecessary delays, and you’ll always receive a clear timeline before work begins.
Can my granny flat be used as a rental property?
Yes, many Melbourne homeowners build granny flats specifically for rental income. A properly designed and approved self-contained granny flat can legally be rented out, generating a consistent income stream from your existing property. We ensure all compliance requirements are met for rental use.
Will the granny flat affect my existing home?
No, we design everything to work alongside your current structure without disruption. Your main home remains fully functional throughout the build process, and the finished granny flat is designed to complement your property rather than impose on it.
What block size do I need for a granny flat?
Block size requirements vary depending on your local council and the specific regulations for your suburb. With 20+ years of Melbourne experience, we assess your exact property during the consultation and tell you precisely what’s achievable, before you commit to anything.
Do you provide a detailed quote before starting?
Always. We never begin work without providing a clear, detailed quote first. The key is knowing your numbers upfront, with 20+ years of granny flat builds across Melbourne, we can accurately price every aspect of your project and keep you informed if anything changes along the way.
Ready to Add Space, Income & Flexibility?
The first step is simply understanding what’s possible on your property. Clear advice, no pressure, just expert guidance from a team with 20+ years of Melbourne experience.
