Hi all. So she’s base complete. It’s treated timber set on posts 50mm off the soil. From the top I’ll be putting in 25mm Celotex taping and then putting the flooring down. My question is should I put something on the underside (connected to) of the frame. Protecting the underside from wind and critters? Will be a bit of an arse to get to but I hadn’t really considered it before starting. Thanks in advance.
