About this design
60m². 2 bed, 1 bath. The Raya is one of those designs that just works — 2 bedrooms, living space, porch, bathroom and separate laundry, laid out without overthinking it. Straightforward to build, easy to live in.
Raya is bright and welcoming—a banner of good design. This 60m² layout with two beds and one bath is built to be noticed for the right reasons. Flow, warmth, solid execution. That's what happens when Buildana approaches a design with intention. Not rushed. Not cut down to cost targets.
Purposeful design backed by proper execution.

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 75m² (perimeter 32.6m × 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 32.6m, 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 gives Raya its 'welcoming' feel?
Three details. The entry opens onto the living, not a corridor — first thing you see is a window, not a door. The kitchen island faces back into the room rather than against a wall. And the bedroom doors are recessed off the main wall plane, so the living reads as a single uninterrupted volume. Those three moves do more for how a 60m² dwelling feels than any finish upgrade.
Does the Raya go through CDC or DA?
Almost always CDC (Complying Development Certificate) — that's what SEPP (Housing) 2021 was set up to enable. CDC is faster (10 working days statutory) and cheaper than DA. The Raya only needs DA if your block has heritage overlay, bushfire BAL-29 or above, flood zone, or a council that's opted out of CDC for secondary dwellings. We confirm which pathway applies during the free block check.
Will the Raya fit on my block?
Under SEPP (Housing) 2021 you can build a secondary dwelling up to 60m² on residential lots of 450m² or more in NSW, with required setbacks (typically 3m rear, 0.9m sides). The Raya's built footprint sits inside that envelope. We do a free block check off your title plan before you commit — it tells us in writing whether the Raya fits and which approval pathway (CDC or DA) applies.
How long does it take to build the Raya?
Allow about 14–18 weeks on site once the slab is poured, plus 6–10 weeks for design, engineering, BASIX, CDC or DA, and pre-construction. Total wall-clock from signed proposal to handover is typically 5–7 months for the Raya, weather and council pace dependent. We update the program weekly during construction so you can see exactly where the build is up to.
