We're hoping to put up a portal framed shed as a general store. The land is designated as being within the curtilage of the house. This means we can do it as a permitted development, which the planners have confirmed. It also means it has to have building regs approval because it's over 30 sqm. It's this that I'm looking for some help with.
The shed will be in the corner of the plot 2-3m from the boundaries. The boundary along the end of the shed has a public road on the other side and the boundary along the long side has a field (not ours) with sheep in it; open countryside in planning speak. I've spoken to two building control bods, one council and one independent, and they both said the walls of the shed would need 30 minute fire resistance to protect whatever is on the other side of the boundary.
I've spoken to the people who've quoted for the shed and they've never heard of the fire resistance requirement and, looking around I've looked at loads of similar buildings near boundaries and roads and have yet to find one with any special provision for fire resistance so I'm at a loss as to potential solutions.
I wonder if anyone has has encountered this problem? Potential solutions might include using fibre-cement roofing sheets on the walls instead of our preferred castle board (one of the building inspectors said that steel sheets wouldn't do), using concrete panels or maybe lining the timber with plasterboard? Timber treatments don't seem to give 30 minutes protection.
It would be great to hear from anyone with experience of how to meet this requirement without spending a fortune to protect a few sheep who would presumably just go and stand somewhere else if the shed caught fire.
