   Hi
   
   Im doing an extension and almost ready to order all my blocks etc.
   
   I was planning on buying 7n Concrete Blocks for the footings, but Ive just seen on the web Celcon Foundation Block 3.6N.
   
   What blocks do I need for these foundations?
   
   Thanks

   Either or will do, the 7N will be heavier to work with, how much have you got to in terms of depth to ground level, if it's not more then one or two course's I would use 7s.
