help me replant my garden

[goshhhhhh]

So....I have a challenge. I have a north east facing garden with a plum tree, green Gage, Apple & pear tree. I am thinking along the lines of woodland planting & I have a few shrubs. I need ideas for plants.

It is ok for spring plants but less for summer colour & I have some areas with little winter structure. I need some ideas that don't cost a fortune as quite a lot to replant. I am happy to do over a period of time & grow from seed.
I have the added delight of wet shade & dry shade.
Happy to grow pots as well as planning to put some patio in. (Anyone have any ideas for lovely patio stones that don't cost a fortune?) Ideas v v welcome. I need some inspiration as I fear what I really like won't work here.
