Gardening help needed

Hi all! Our garden hasn't been properly taken care of for over 2 years by previous owners. We're looking to completely redo it.

• Our garden is situated towards the north
• At the bottom right is our dining room
• We love some natural patterns rather than one square terrace and one square greenery
• We want lots of plans, grass and places to chill. Especially in the evenings (often top right)
• We have a huge L shaped bench and a large table with six chairs to fit somewhere as well
• The garden is surrounded by a natural fence made of plants.

Would love to receive some tips and tricks! Thanks a bunch in advance
