Where the money goes
Estimated breakdown for your configuration
A two bedroom flat usually costs only about 10 per cent more than a one bedroom of the same footprint, because the expensive rooms (kitchen, bathroom, laundry, switchboard) are the same either way. The second bedroom is close to the best value square metres in the whole build.
Most states cap a secondary dwelling at 60m2 of internal floor area, which fits a modest two bedroom layout with little margin. Above that you usually lose the fast complying development pathway and need a full development application, so confirm your council's exact limit before designing bigger.
Ask any builder whether their price is fixed or subject to a soil classification. An M or H class reactive clay site can add $8,000 to $20,000 in footing upgrades that a P class quote simply did not include.
Ways to save
- Build within the state exempt development pathway rather than lodging a full DA. In NSW the SEPP allows a complying development certificate for a compliant 60m2 secondary dwelling, assessed by a private certifier in roughly 10 to 20 days rather than the two to four months a DA takes. That time saving is real money in holding costs.
- Position the build to reuse the existing services. Every metre you move away from the main house adds trenching for water, sewer, power and data at roughly $80 to $150 per metre, so siting the flat within 10 to 15 metres of the existing connections routinely saves $5,000 to $12,000.
- Standardise the design. Builders who repeat a small number of two bedroom floor plans buy trusses, windows and cabinetry in volume and can price 10 to 20 per cent below a custom set of drawings.
- Get the soil test and a survey done before you sign anything. Together they cost around $1,200 to $2,500 and convert the two largest variables, footing design and site levels, from unknowns into fixed line items.

What a 2 bedroom granny flat costs in Hobart
A two-bedroom granny flat in Hobart is costed by the floor area of the secondary dwelling, the fit-out, and connecting water, waste and power, because a granny flat is a small self-contained home with a kitchen, bathroom and two bedrooms on an existing block. The area and fit-out lead the figure, with services, footings and access adding to it. The small Tasmanian market with limited competition keeps the build firm, and specialist materials can carry island freight.
Hobart's cold, damp climate makes insulation, double glazing and heating a serious part of a granny flat's cost, as a small dwelling must stay warm through the long winter. The sloping sites common around the city can mean a stepped or pole footing to sit the granny flat level on the fall, which adds to the build. Tasmania allows an ancillary dwelling on a qualifying lot, with rules worth checking, and a heritage property can constrain siting. The colonial and weatherboard character may shape the design. The small market can stretch the timeline. A licensed builder constructs the dwelling, with a licensed plumber and electrician for the services.
A granny flat is a dwelling that needs a licensed builder, with council planning and building approval, and licensed plumbers and electricians for the services, in Tasmania under the state regulator. For a Hobart block, the clearest way to price a two-bedroom granny flat is by its floor area, the fit-out and the services, with cold insulation, sloping sites and the small market the factors.
