Modularised OSM Wall Panels© are the foundation for the building system and complies with New Zealand standard (NZS3604).
Produced in a dry, controlled factory environment by local Frame & Truss plants nationwide and there are no requirements to invest in expensive machinery or a large single factory. Standardized and can be manufactured cost efficiently in production runs and to stockholding.
Installation of wall panels and construction on-site are carried out by licensed building practitioners (LBPs). Allowing the house to be weather proof within a week and achieving practical completion in only 3-4 months after concrete pour. Optimised designs enables the builder to work more efficiently with familiar installations and with less waste of material on-site.
Economy of scale and standardisation in combination with OSM Wall Panels© reduces the construction cost with up to 20% compared to conventional build.
