I have built a cabin in place of a static caravan.

 

What would be the most cost effective way of cladding the exterior? I want to repurpose it for long term use. As such something quite stable. Personally I would use feather board but that's aesthetically a no no. I could render or weather board. It has an OSB exterior. I don't want to spend money as prices have really shot up and have to be careful with the main build finances 

.

 

 

Thanks all

Tongue and groove looks smart, and can be stained to retain or jazz up the appearance, or left to go grey as you choose.

Gap behind between your fixing battens for ventilation, and vapour barrier on the osb.

Planning?

I used cedar over lockdown Looked great But I suspect the price has doubled since 

Steel roofing sheets ?  £15 sqm something like that.  Some beautiful buildings on Pinterest that are clad in steel sheets.
