To ensure the proposal was able to meet or exceed the extremely high bar specified within Paragraph 55 of the NPPF, the design team were able to demonstrate how the proposed structural system would benefit from the off site manufacture, predominantly using locally sourced materials and skills.
The Panel suggests that there may be an opportunity to further demonstrate innovation to an even greater extent in terms of procurement and off-site construction techniques; it is suggested that there may be an opportunity to demonstrate the creation of a locally procured pre-fabricated structure, that utilizes local/regional materials. It is felt that this would be innovative, demonstrate an enhancement to the vibrancy of local communities, and provide learning outcome that may help to inform how the standard of design in rural areas could be generally improved.
Virtually all major components manufactured offsite
It was felt essential to create a scale model of the building so that it could be carefully studied. This enabled various detailed and peripheral viewpoints to be observed which in turn offered a greater understanding of the offsite manufacturing strategy. One added benefit was the ability to adjust ‘real” lighting to understand the angle of the panels at different times of day (and seasons).
- Foundations: There would be no concrete used in the foundations. The screw pile foundations and connecting brackets would be manufactured offsite.
- Structural Frame: Manufactured offsite in component parts which would be assembled on site on top of the screw pile foundations.
- Wall Panels: Manufactured offsite and erected on site. The heat sink components incorporating piping and insulation would be manufactured offsite in sizes that facilitated simple erection on site. The panels would sit in between the post and beam chassis and would be insulated before arriving on site.
- Roof Panels: Manufactured offsite and erected on the post and beam on site. The panels would be in easily transportable sizes obviating the need for large delivery vehicles. The insulation would be fixed in the panels before arriving on site.
- Floor Panels: Manufactured in a similar way to the roof panels.
- External Finishes: It is intended to not use any of the wet trades and as such many of the finishes can be cut or shaped to size offsite to enable simpler erection on site.
- Internal Finishes: Most of the internal finishes would be carried out in the traditional manner.
