I'm replacing a rotten shed floor. The 3x3m shed was built on the floor, so I jacked up the walls removed the rotten edge 38x38mm bearers and OSB, laid 38x70mm treated timber on blocks with DPC in between, and lowered the walls down again. The whole shed is built on a concrete slab.
My intention is lay a new floor of 15 or 18mm plywood inside the walls this time, with the edges resting on the edges of the new bearers, and to lay more 38mm bearers on more blocks to support it.
How would you sheet the floor and how many bearers do I need? Two full sheets then lay remainder with cut down pieces? Or, run a main bearer down the centre of the shed with sheets finishing in the middle? Bearers every 500mm?
Any smarter way to do it that'll let me cover it without needing a 4th sheet of ply?
