I agree that might be useful. Also very useful if the OP wants further advice 
would be for the OP to post a follow-up with R code that creates a minimal 
example and show what a correct answer would look like.

If each block were homogeneous, the answer might be simpler than if the values 
in the blocks could be arbitrary. It would be helpful to know what sort of 
specification for the dimensions of blocks might look like. Simpler would be 
square blocks.
