Fruit garden

I am giving serious consideration to changing part of my veg plot to fruit. I want to plan it out so any help would be appreciated. I already have an apple espallier and a pear, rhubarb, gooseberrys and strawberrys. What I need is some idea of how to plan it into Veg/Fruit. My plot is 5 metres x 25 metres. I would estimate half and half being about right for my needs.

 

Not sure about the planning but I would add blackberries, raspberries and blackcurrants
