About this design
Not every secondary dwelling needs to be complicated. The Hana is 60m² — 2 bedrooms, living space, bathroom and separate laundry — and it fits on most standard lots without drama. Good bones, solid layout.
Hana is simple and warm—universal acceptance. This 60m² design with two beds and one bath is built to work for anyone. Honest space, honestly built. No pretence. No compromise. Buildana builds this way—with the conviction that secondary dwelling space deserves the same care as anything else on your property.
You're not settling. You're building with integrity.

Exterior finish system
Choose the wall system for the external envelope. Pricing below is calculated against this design's external wall area — approximately 79m² (perimeter 34.3m × 2.7m wall height, less 15% for openings). Standard polystyrene-render is included; Hebel, face brick and brick-render are priced as upgrades over standard.
Foamboard polystyrene cladding system finished with cement render and texture coat. Included in the base price — light, fast to install, and the standard exterior on every Buildana granny flat.
Ceiling height
Standard ceiling height is 2.4m. Higher ceilings make small footprints feel larger and lift natural light through windows. Pricing below is calculated against this design's external perimeter 34.3m, covering the extra wall framing, plasterboard, render/cladding and cornice/painting needed to raise the envelope.
Standard ceiling height across all Buildana granny flats — already 100mm taller than the BCA minimum for habitable rooms. Included in the base price.
Doors & highlight windows
Door height and highlight-window upgrades. Tall doors are typically chosen alongside the 2.7m or 3.0m ceiling upgrade so the proportions stay right.
Slim 300 x 600mm highlight windows for natural light to bathrooms, ensuites, hallways, walk-in robes or above kitchen benches. Frosted or clear glazing. $1,100 each, supplied and installed. Pick how many you'd like below.
Premium fitout
Lift the standard spec to higher-end finishes.
Air conditioning
Choose how the granny flat is cooled. The standard living split is included in your base price.
Included as standard. Wall-mount inverter split unit to the living area, sized to the room load.
Outdoor & site
Pricing varies with site conditions, falls, and existing services. Final figures confirmed in writing after a site visit.
Compliance, services & metering
Almost always required for tenanted secondary dwellings. Pre-ticked by default.
Add-on rooms & layout changes
Layout extensions are quoted from your block survey — they may need a fresh CDC/DA pathway.
Common questions
How does Hana avoid feeling like a bedroom block?
Two things. First, the kitchen sits inside the living envelope rather than tucked behind a wall — so when you walk in, you read 'small home,' not 'corridor with rooms off it.' Second, the meals area gets a window of its own, not a borrowed one. That's why Hana feels lived-in even on the day the keys are handed over.
Is the Hana BASIX and SEPP-compliant?
Yes. Every Buildana design is built to current BASIX targets (5-star minimum as standard, 7-star available as an upgrade) and within SEPP (Housing) 2021 thresholds (60m² internal, single storey, single secondary dwelling per lot). We run BASIX modelling specific to your block's orientation and shading before lodging — not a generic certificate.
What construction system does Buildana use for the Hana?
Concrete slab on ground, timber wall framing to AS 1684, metal-deck roof on engineered trusses. Exterior cladding is your choice from poly-clad weatherboard, Hebel power-panel, face brick or rendered finish. The build system is identical to the larger homes Buildana puts up — same trades, same standards, same warranty. Granny flats aren't a separate, lower-grade product line for us.
Can I customise the Hana floor plan before contract?
Yes. Every dimension and room layout is fully customisable up to the point we lock structural drawings for engineering. Most clients adjust at least one room — bedroom 2 sizing, bathroom door direction, kitchen length. Bigger changes (adding a bedroom, removing the porch, splitting the laundry off) need a fresh layout pass and may shift the indicative price. Small changes don't.
