Non standard size concrete blocks All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

Hi all,

I am trying to find out if there's an easy way of sourcing some non standard sized concrete blocks. The standard size seems to be 440mm x 215mm x 100m, but I'd very much like to find some that are a little taller - say about 440 x 250ish x 100. Do I have a chance?
