One of the great things about an allotment is the way it fights one's ordered mind. I had planned 5 beds of roughly equal size. The reality is 4 beds of different sizes. The previous system was designed so that I could literally rotate crops, (clockwise, for goodness sakes!) around the plot. One needs more subtlety. I'll be thinking from hereon in about patches rather than beds. So long as I mark (and blog), say, where a tattie patch is, then I know not to plant tatties or tomatoes there for 3 or 4 years.
Bottom left of the plan is the long bed, currently about 20% riddled. The white rectangle is the poly-tunnel, but that is going to be moved every year, (counting as tomatoes/tatties in the rotation). The shadowy ovals are the shadows cast by the cherry trees (bottom right-ish) and ash tree, (top left-ish). The purple-ish oval is the pond, (maybe not to scale, I haven't measured it). The dark red areas are paths, the skinny paths will all be removed except for the one at right angles to the central path, by the pond, which is covering a drain.
I've allowed 3ft for the width of hedgerow, which it will grow to in the next couple of years. The dark blue rectangle is the base for the shed, and the orange is the shed itself. In the top left hand corner is my temporary tool store and rain shelter, which I've grown quite fond of, and will retain.
