We build free-standing secondary dwellings (granny flats), one or two bedrooms, small homes. Using customised or standard designs we cater to seniors, families or individuals. Modern, energy efficient, and user friendly. https://www.greatgrannyflats.com.au/floor-plans

In NSW Granny Flats can be built up to 60 squared metres floor space. That is the maximum size allowed, comfortable enough to include two bedrooms. Note, attached decks or pergolas, for example, are not included in the floor calculations.

You can have a granny flat built on your block if your land is 450m2 or greater and has a minimum street frontage of 12m. Siting requires a rear setback of 3m and 900mm to the sides and 3m clear of trees taller than 6m (subject to your LEP). On larger lots setbacks are increased.

Once construction begins, and with unhindered progress on a straightforward block, best case scenario is around four months minimum to completion. Custom designs will take a little longer.

If your project can fit within the state planning requirements for complying development then you do not have to use council. A private certifier can do a fast track assessment of your project.

Being a habitable permanent building structure and one that increases the value of your property, , building approval is required. This is to ensure your building is built at or above minimum standards of safety, amenity and longevity, and appropriate for the area it is built.

DA stands for development application, and refers to the council led concept assessment. DA’s are required when there are significant area/property affects or proposals outside the planning guidelines. Allow months for a DA assessment.

CDC means complying development certificate. Unlike a DA, a CDC is a one step building assessment that typically only takes weeks (not months like a DA). CDC’s have fixed parameters you need to achieve, e.g. sizes, heights, setbacks, locations etc. If you can meet these obligations, then a CDC is the preferred pathway.

Each property is unique and each property needs to be individually assessed. Things like what zoning its in, if the property is affected by any hazards like bushfire or flooding, if there are any easements and any other specific regulations that may affect your block. No two properties are the same

As part of our process, we clarify these impacts, design and construct accordingly. This ensures your build is constructed to the planning codes.

We offer competitive pricing and fixed price contracts based on project type and complexity. To avoid price shock on custom projects, and ensure an achievable build, we collaborate with you and the designer from the start.

Age in place refers to staying on at home as you age instead of moving into a retirement village. This has become a more popular choice especially when other family members share the same address. The choice familys’ make is to build a separate dwelling (granny flat) in the backyard to allow ongoing independence and privacy for the elderly (or vise versa) while still being close by

Features include reinforcing for stability supports, building wider passageways, forming functional work areas and eliminating steps. Occupants can move in to a clean dust-free ready-made home. The beauty of constructing a granny flat specifically for age in place is that support features can be installed during the build, saving on disrupting and inconvenient retro-fits, some of which require significant modifications and cost.
