About this design
Need 2 bedrooms in under 60m²? The Selah does it — 2 bedrooms, living space, porch, bathroom and separate laundry, laid out so the living area gets priority and the bedrooms are still a proper size. Customisable across finishes and fittings.
Selah means pause and reflection—a place to rest. A granny flat designed with this in mind is a genuine refuge. This 60m² layout with two beds and one bath is built for that purpose. Comfortable. Quiet. Right. Not every dwelling needs to be loud or impressive. Sometimes it just needs to be solid and peaceful.
Selah is that design.

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
Is Selah suited to a short-stay rental like Airbnb?
It's one of the two designs we'd point you to for short-stay (Selah and Avalon). Reasons: the entry is its own threshold, the living-bedroom separation is real (not just a half-wall), the bathroom takes a hotel-style level-entry shower as an upgrade, and the kitchen is small enough that it doesn't read as a permanent residence. Check your council STRA rules first.
How long does it take to build the Selah?
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 Selah, weather and council pace dependent. We update the program weekly during construction so you can see exactly where the build is up to.
What's actually included in the Selah 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.
Can I rent the Selah out as a separate dwelling?
Yes — this is exactly what SEPP (Housing) 2021 allows for. The Selah 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.
