Hello, if you just need a planting scheme, I can do it for you and you get a gardener to plant everything where I'll tell him.
I have redone my garden entirely from scratch (removing most of the overgrown stuff, then re-planting to get year-round interest with a mix of evergreen and perrenials/annuals) which was c 1000sq ft.
We now moved to SW11 and I just re-did the planting of our small garden (no turf this time though), with again year-round interest and a white and green scheme. I will spread some new clean gravel, I ordered nice furniture, hanged some stringlights and added some others lampions and I should get a nice small boho-chic garden with a dinner and a chill area, without breaking the bank. A good clean and the right "accessories/plants" is enough.
I don't have photos for my current garden as it's not grown yet but you're welcome to come and have a look.
I do have photos for my previous one., let me know and I'll email.
Now's the good time to do it.
If you need landscaping etc then you'll need a proper company.
