Morning all. Building my garden room and wondering what to put on top of timber joists as a subfloor. Base is floating on 12 piers, plenty of air flow. Doing mainly on my own so things taking a bit of time. For that reason and although I will keep it covered whilst building walls and roof, would osb3 or ply be better. Was wondering to keep costs down if osb3 with a coat or 2 of varnish would suffice (Decorator by trade). TIA
Garden room subfloor, osb3 or ply

I'd use OSB. You can get tongue and groove variants btw, coupling with expanding urethane glue works well
