Tekna Homes · South East Queensland builder · QBCC 15344273
Data to Sep 2026We only build what the data backs.
We’re a South East QLD builder. Our data picks the suburb and the inclusions, so every deal is one you can defend to your client.
The problem
New builds are easy to get wrong, and hard to defend.
You carry that risk with your client. We built our process to take the guesswork out of it.
How we solve it
Data decides where we build, and what goes in.
More on how we decide
- Priority Development Areas: three years on, prices grew more slowly than similar nearby suburbs. Extra supply matters.
- Current Hedonic model: 30 of 57 features significant.
- We’re paid to build, not for the land, so we back whichever block the evidence favours.
The proof · Southside duplex, Johnstone Rd
Here’s the data in action.
A 4-bed duplex in Southside, Gympie. Per side · gross · tap any number for its source.
Why this area
Tight rentals, a growing population and steady sales. We scored it 3/5 overall and show the weak spots too: supply and flood history.

What we’re building, and why
Ducted air and 2.74 m ceilings are standard. On top of that we add only what the data says earns its keep.
Ducted air and 2.74 m ceilings are standard in this build. Each dot shows that item on its own; the benefits overlap, so don’t add them up. The package is capped at ~$30k.

Smaller extras · each on its own
Don’t add these up. Homes with one tend to have the others, so a stacked total isn’t credible.
We back ourselves on it
Land settled Oct 2026 and we’re building it ourselves. The gross numbers, caveats beside them, are below.
The feasibility, gross
2 × $715k = $1,430k, less $944.75k land + build. This gross profit uses $715k per side as a conservative arithmetic anchor only — see nearby sales caveat (Farmer Ct $725k 3-bed duplex/semi; Brickfields $715k may be a house). Before fees, duty, holding, selling and tax. End value to be confirmed by valuation; no bank valuation yet. Not a promise of returns.
Upgrade costs (ceilings standard — not listed)
- 900mm appliancesU9A · measured +5.1% (n=34 · 95% CI +0.8% to +9.6%); package uses conservative ~$17k$2,700

Per side, extra over builder’s grade, supply only, may exclude GST. Ducted air and 2.74 m ceilings are standard on Johnstone Rd — not listed as upgrades. Mirror + tapware + concrete + checkerboard ≈ $8.2k; with tiles and vanity (no ceilings), optional extras ≈ $13.6k a side — cost, not added value. At the ~$30k measured package cap the recommended set is colonial skirting, floating vanity, 900mm appliances and floor-to-ceiling tiles: cost ~$5.4k, value lift +$30k (package cap), net ~$24.6k. 900mm contributes a conservative ~$17k inside that cap — do not also add +5.1% on top.
