Not really have a circle that is squared off ie slabs that match the circle. try googling squaring off stone circle or looking up on Homebase or similar site. then take out with how far you need i.e. removing all grass
The small part of the garden is now cut to size but needs a few more plants. I also had a visit from a lovely woodpecker who often appears - he probably lives in the nature reserve which the garden backs onto.
If I may make a small suggestion.
If I were you I would first work out a budget you intend to spend before thinking of any garden designing.
All too easy to overspend having gone half way in any alterations
Me overspend? No No!! As for a budget…I have far more important things to spend money on, so this is a “what can I do for the least amount spent” project. Trying obviously to make as good a job of the project as possible.
With a decent budget - I could have all new paving, patio, drive etc etc… but I prefer to spend on other projects … me!! One life…live it!! 
Edit - there should be two more photos - similar to the ones pre-project!
My garden is small and oblong its mainly lawn which is akin to a bumpy field but I don’t want to dig it up too much work I want to build a feature well but don’t know where to put it . I have too much gardening junk everything is a mess , I need ideas .
Was going to post some pics but it looks to awful .
I think an oblong garden gives far more possibilities than my square garden. Such as…imagine a path from one end to the other…curving around with various features and planting … seating in shady areas…and seating in sunshine. Lots of possibilities there.
Garden project almost finished. Still looking for a Cornus Alba - hole dug ready for planting and need another three bags of gravel/pebbles - hopefully in stock from this afternoon.
The labouring man I’d arranged, disappeared. Rather than sit around idle, I’ve done the whole job myself. Fortunately I back onto a nature reserve and the turf I’ve taken up has created a pile almost as high as I am…and that will create a barrier for anyone intending to venture into my garden :shock: and a good source of compost in years to come.
Well done Lindy !
I have got no further I need a patio put down and had selected some pavers but found the actual ones I wanted cost £2000 pounds - that’s before the labour costs . They were called weathered forest and the builders suppliers had quoted for forest ( half the price )
This sounds good Lindy but it needs someone to do it I need the Rich Brothers and Charlie Dimmock .
My patio will have to do as the cost of replacing all the paving I have would be astronomical and I’m not sure swanky new paving is in keeping with the house.
My next outside jobs are to make some stepping stones and perhaps a few pots from hypertufu as B&Q have finally opened and I’ve manage to buy some cement!!
At the moment I have nothing the builders left such a mess
Why don’t you ask for some quotes now? So many people are desperate to get work they’ll be very keen to give you a good quote.
I’ve just found a book with some good ideas for paths etc - I’ll take some photos and post them later on.
Thank you
