About this design
The Zahir is 60m² with 2 bedrooms, living space, porch, bathroom and separate laundry. Nothing tricky about it — which is the point. A design this straightforward builds faster, prices more predictably, and gives the occupant a space that makes sense from day one.
Zahir is clear and radiant—transparent delivery at every stage. This 60m² design is exactly what you see. Two beds, one bath, full Buildana spec. No hidden compromises. No surprises that surface later. Transparency is part of Buildana's Amanah foundation. Zahir embodies that—you get what you see, built how you expect it to be built.

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 77m² (perimeter 33.5m × 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 33.5m, 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 does 'transparent build' mean for the Zahir process?
It means three documents are issued before contract: the line-itemed inclusions schedule (every fixture, every fitting, by SKU where possible), the site-cost assessment (excavation, retaining, services — costed off a real measure-up, not a postcode generic), and the variation register (any items 'quoted on assessment' from the configurator turned into real numbers). Nothing surfaces during the build that wasn't on those three documents.
What's actually included in the Zahir base price?
The base price covers the dwelling itself — slab, frame, roof, exterior cladding, full internal fitout, all standard inclusions listed on this page, plus our fixed builder margin and warranty. What's not in it: site costs (excavation, retaining, rock removal), council/CDC fees, separate metering, BASIX upgrades beyond the minimum, and any structural alterations to the existing main dwelling. Site costs get quoted off a real assessment, not a postcode generic.
What construction system does Buildana use for the Zahir?
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.
Will the Zahir 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 Zahir'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 Zahir fits and which approval pathway (CDC or DA) applies.
