Presumably one side will be attached to the house with a wall plate
if that is the case three pads one each corner and one in middle will more
than suffice
don't build column from blocks just cast padstones and thunderbolt fence
post collars to pads 4" x 4"

I am planning to put in a small deck, 3mx3m, and would like some
advice with regard to the number of supports/pads required to support
the frame.

The deck will be on a flat surface and I plan to put in some breeze
block pads, on concrete, and put the deck frame onto these. The
question is how many pads do I need for a 3mx3m deck using 150mmx50mm
joists.

The frame will be 3mx3m with joists running across the frame at 600mm
centres. From what I have read 150mmx50mm joists should be supported
at 3m centres, so do I only require four pads, one at each corner of
the deck, or do I also need pads at each end of each joist, a total of
12 pads ?

Hope the above makes sense !

TIA
