I have quite a large garden and would like to dedicate a portion of it

I have at least 6m x 6m to spare, so was thinking about 4 raised beds,
each about 2meteres square.


That would mean you would be only cultivating 16 sq metres out of a total
area of 36 sq metres i.e less than half of the available spare space!!

Why do you need such big spaces between your beds?


Because he is using Raised Beds which waste a lot of the available space
with paths.
It's why most allotment gardeners use walking boards with few paths, in our
case just one down the middle.

I don't think most people with raised beds make their paths 2m wide
which is what is implied here.
