About this design
60m². 2 bed, 1 bath. The Niko 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.
Niko carries confidence—victory, the people's choice. This 60m² design is built with that kind of sureness. Two beds, one bath, designed and executed with conviction. No hesitation. No compromise. When you build something right, people notice. Niko is what that looks like at scale.

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 86m² (perimeter 37.4m × 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 37.4m, 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
Why is Niko the most-built design in the Buildana range?
Because it's the layout the largest spread of clients agree on — the bedrooms are both queen-size, the kitchen sits where you'd expect, the bathroom doesn't open onto the living, and the living window faces the rear yard. There's nothing about it that's wrong for a typical brief. That's why it gets picked. Familiar isn't a bad thing in a 20-year asset.
Does the Niko 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 Niko 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.
How long does it take to build the Niko?
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 Niko, weather and council pace dependent. We update the program weekly during construction so you can see exactly where the build is up to.
Can I rent the Niko out as a separate dwelling?
Yes — this is exactly what SEPP (Housing) 2021 allows for. The Niko 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.
