Tango 526
Designed for lots from 12m wide, delivering a pair of generous, fully customisable townhouses built from structural insulated panels that assemble at roughly half the time of conventional construction.
Most people with a narrow block never realise what it can accommodate. Tango 526 delivers two complete townhouses across 526sqm with proportions that feel anything but tight, built from a prefabricated SIP panel kit that arrives ready to assemble. Your trades go up fast, the finished homes land on title sooner than most subdivision projects ever manage.

Boxed Buildings. Benefits compared to traditional builds
A conventional backyard build means weeks of site work, weather delays, and trades coming and going for months. A Boxed Building sidesteps most of that. The kit is manufactured off-site, so assembly is fast. Build time runs at roughly half that of a comparable conventional structure, with less site disruption and far less waste.
