I've found a site that gives joist sizes for flat roofs which is near enough what I will be doing.It says 50x150mm at 600mm centres will do a span of upto 2.97m so will do my 2.4 span easily. Just need to find out now whether this would support a green roof of 60-100kg per sq m.

I reckon if you use the tables for floor joists, they will be more than enough for your green roof.
I would never use a green roof personally but everyone to their own

From the net --- C24 graded Premium structural timber is a stronger, more demanding grade and has fewer/smaller knots than C16. C24 is best used where higher loads or wider spans are required. C24 will carry a higher point load than C16 grade.

Cheers will see if I can get some tanalised C24.

What are those bricks in the foreground, just in front of your new plinth?
