We design the unit to suit the yard and your budget, give you a clear cost estimate and handle the permits, which in Victoria are simpler than most owners expect.
Build and handover
We build the granny flat or studio with minimal disruption to the main house, connected, finished and ready to use.

Frequently asked questions
How much does a granny flat cost to build in Melbourne?
Our custom built granny flats and home offices start from $98,888, excluding site costs and permits. Larger fully specified granny flats typically land between $180,000 and $300,000 depending on size, specification and how far services need to run. We give you a fixed price once the design and site checks are done.
Do I need a planning permit for a granny flat in Victoria?
In most cases, no. Victoria's small second dwelling rules mean a self-contained unit up to 60 square metres generally needs only a building permit, provided the block meets a few conditions. We confirm your eligibility at the free consultation.
Can I rent out a granny flat?
Yes. Small second dwellings in Victoria can be rented out, which is why many owners build one as a long-term income stream as well as space for family.
How long does a granny flat take to build?
Allow around 2 to 3 months for design and permits, then 3 to 5 months for construction depending on site access and services. Detached studios are usually quicker.
What is the difference between a granny flat and a home office build?
A granny flat is a self-contained dwelling with its own kitchen and bathroom, so it must meet dwelling standards. A detached home office is a habitable outbuilding without full facilities, which keeps the cost and approvals simpler. We help you pick the right one for how you will use it.
