Offsite construction for an efficient build
Offsite construction for housing developments and commercial construction has a number of benefits:
- Build accuracy. Ensures components are built to exact specifications in a controlled factory environment
- Less on-site disruption. Each component of the panel is constructed and assembled offsite, from the external breathable membrane to the internal timber service battens.
- Reduced on-site labour. With a large proportion of the build manufactured offsite compared to traditional methods of construction
- Less waste. Prefabrication minimises on-site cutting and construction reducing waste and disposal costs.
