About this design
60m², 2 bed, 1 bath. Most granny flat buyers overthink this. The Cove has 2 bedrooms, living space, bathroom and separate laundry — everything you need, nothing that'll blow the budget. Fully customisable if you want to make it yours.
Cove is shelter—a protected place. And that's exactly what a granny flat should feel like. This 60m² design with two beds and one bath is built with that purpose in mind. Secure. Private. Cared for. Whether it's family or tenants, the people in this space need to feel safe and looked after. Cove delivers that.
Not through luxury. Through thoughtful, solid design and build quality that respects the responsibility of the space. This is a design built with genuine purpose.

Upgrade options
Tick what you want — your indicative total updates live. Final fixed price comes back in your formal proposal after a site assessment.
Exterior finish system
Choose the wall system for the external envelope. Pricing below is calculated against this design's external wall area — approximately 76m² (perimeter 33.2m × 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 33.2m, 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
What makes Cove feel more self-contained than other Buildana designs?
Cove's entry is set back behind a covered porch instead of opening straight off the path, and the living window faces away from the side fence rather than the street. The result is a footprint that reads as its own dwelling from outside the block, which matters for tenants who want their own door, and for elderly parents who want their own threshold.
Can I rent the Cove out as a separate dwelling?
Yes — this is exactly what SEPP (Housing) 2021 allows for. The Cove is built to be tenanted independently of the main house. To do it cleanly you'll want separate water and electricity metering (configurator option above) so the bills sit with the tenant, plus the BASIX 7-star upgrade to keep their power bills competitive. We'll flag any council-specific tenancy conditions during the block check.
Is the Cove 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 Cove?
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.
