First of all, sorry for bad English.
When I examinated the area you had given, as you said, many out-of-use products were at the forefront.As we can see from the photos, we tried to seperate what we could use and use it in the area we renovated.
We created an dining area as you like, surrounded it with evergreen plants and designed an area intertwinem with nature.
We chose to use the benches seen in the photos for the seating area and created a special area of wood for the fire-pit.
We continued to use the stones avaible in your garden and replaced several of them in a way that would suit us.
We preferred tall plants and fragrant plants to prevent noise from outside wall and remove dust from living area.
