When you acquire an allotment it may have been well cultivated and you will have to be adaptable and be prepared to move things round to get the best results, crop rotation is a time tested and centuries old form of keeping the land cultivated and sound. You will also need to be prepared to change around when crop failure occurs. On the other hand it may have been neglected an be full of old rubbish, stones and bricks etc.
That said the next task is planning how you will use your plot space. Traditionally allotments are simply organised into beds which are four or five feet wide with paths on either side to allow access. Of course this will depend on what you want to grow.
Take a good look at your planting space. Take into account which way it is facing. Where the
sun shines most. Which parts are not so easy to access. Is there a lot of foliage. Your next step is to make yourself a rough plan as to where you would like to place sheds, compost heaps, hen houses and runs, is there space for a green house or poly-tunnel. The hardware of your allotment should be positioned with easy access but which also allows you to achieve the maximum growing area possible.
A lot of gardeners like to edge narrower beds with wood, leaving enough path space to kneel and a well-defined two row bed that can be easy to tend to from either side. I prefer a larger area to work in to save leaning over and where I can get a larger crop. As a general rule areas sectioned off with wood to make square areas of around 3 metres with paths between. In the end it is all about the area you have to work with and your own preferred layout - there are no hard and fast rules.
