Flexible design: homes, social infrastructure, hotels and neighborhoods are designed to meet the
varying needs of customers, citizens and target costs (not a rigid 1-model approach) leveraging a
combination of skills (urban development, architecture, housing design and supply chain).
Component standardization: components from three families are designed specifically for each design:
H4A-M for up to three-floor buildings: galvanized steel structures, fiber-cement external walls,
vegetable-fiber internal walls and interior panels, and rock-wool insulation materials; H4A-C for three to
eight-floor buildings: pre-cast concrete structures; Stone coverings (and other decorativematerials) are
easy to add to internal and external walls.
Open building system: H4A allows for flexible selection of specific materials based on local availability
and requirements, and cost options (eg. different options of vegetable fiber panels).
Modularity at 5 levels (component, home, residential unit, block and neighborhood).
Lean supply chain: H4A implementation is based on lean manufacturing (at supplier site), lean
distribution to sites and JIT assembly principles (at the construction site) enabling quality, speed and
target costs. |
