Oak Tree Dwellings
Granny flats have evolved
12 designs, a clear process, and a project manager working for you from first sketch to handover.
Why Oak Tree Dwellings
A project manager working for you, not the builder
We tailor every build to your needs, budget, and land — coordinating design, permits, and construction as your client-side project manager, working alongside the architects, builders, and council on your behalf.
NDIS specialists
We design and build to NDIS specifications, with staff trained in accessible and specialised inclusions.
12 designs to choose from
Every block is different — where land size or access doesn’t suit a standard layout, we adapt the design to fit.
Coordinated from day one
We coordinate materials, trades, and scheduling with your builder, so the process runs smoothly from start to finish.
Flexible use
Ideal for multigenerational living, rental income, or a dedicated space of your own — no restrictions on how it’s used.
Good news for Victorian families
Victorian homeowners can now build a secondary dwelling without a planning permit, on lots over 300m² without environmental overlays. The new dwelling must be at least 60m² and can be used for family accommodation, guest housing, or rental income.
Building permits and ResCode rules still apply, and a secondary dwelling can’t be subdivided and sold separately from the main house — it stays part of the one title. We’ll walk you through exactly what applies to your property as part of our project management service.
12 designs, one standard
Our process
How it works, step by step
Every project starts the same way, then splits into two paths depending on how involved you want us to stay.
01 — ENQUIRY AND FEASIBILITY
We check your land is feasible to build on and take the time to understand what you need. This stage ends with a fixed quote for the concept we’ve developed together.
02 — DESIGN
Choose from our standard plans suited to your site and your goals, drawing from our 12 existing designs or starting fresh if your block needs something custom.
03 — PERMITS
We manage all drawings, engineering, and all documentation required to obtain your building permits so you don’t have to chase any of it yourself.
From here, it's your choice
Two ways to build
Once your plans and permit are sorted, you decide how involved you want us to stay.
Builder Networks
We have builders ready to take on your project across the country and aren’t limited to region. With our builder network we tailor your project to the right builder and oversee the entire project from start to finish. You stay updated throughout, but the day-to-day coordination is on us.
Owner Builder or find your own builder
You purchase the plans, we coordinate the permit, and you bring your own builder. A lower-touch option if you already have a builder in mind or want to manage construction yourself.
Let's see what your block can take
Check your land against our 12 designs, then let us know whether you’d like full project management or just the plans and permit — we’ll take it from there.
