Full record of creating a 50 sq m terrace garden, netizens exclaim it's so nice to have a terrace

Record of creating a 50 sq m "terrace garden", a round of applause first, the terrace finally started construction after much dawdling, tears streaming down my face.
No time for DIY, so I found a gardening company, all young people, communication was no problem, after looking at my hand-drawn floor plan, everyone got excited..
Original state.
Demolition begins! (From here on all photos were taken with a phone. Too lazy to carry the big camera.)
The soil in the old flower bed was filled by the developer, not a bit of construction waste, truly pristine. Moved it inside for later use, since the indoor renovation hasn't started yet..
Washed clean with water, preparing to do waterproofing. PS, a rare blue sky with white clouds.
The water was shut off while cleaning the terrace, the water meter was broken, going crazy. Wandering around the neighborhood, I saw the first apartment I had my eye on, with a garden at ground level, but gave it up because my dad said he was afraid of dampness. But a ground-level garden is so much less trouble, at least you don't have to worry about waterproofing and weight-bearing at all. After not seeing it for two or three months, they've created quite a grand scene. Wrought iron gate, white marble railings, a huge addition, a huge water feature..
Building the flower bed today, crouched watching for a whole morning, moving bricks back and forth, the flower bed was widened again and again.. Now looking at it I feel the flower bed is still too small!
At the other end in the corner is the water feature, and there's also a water tap.
The drainage pipes, there will be an inspection opening in the corner, so if it gets clogged it can be opened anytime to clear it, forgot to take a photo.
The bricks at the very bottom all have gaps left, for drainage.
It rained yesterday, went to check at noon today, no progress.. But supposedly the treated wood will arrive tomorrow, been busy these two days, didn't stay on site to watch, the flower beds already built have problems in several places, need to knock them down, knock them down! So dizzy!!
The square foundation in the foreground is for the future wooden platform, it's too small, needs to be made bigger, knock it down!!
The water tap by the wall in the distance is too high, the shape is also very ugly, the wrong bricks were used, knock it down, knock it down! Also there are several places at the base of the flower bed wall where drainage holes weren't left, need to redo.
The red circles are the flower beds that were demolished
There's still one pot where I haven't decided what to plant, and the other herbaceous flowers haven't been repotted either.. Haven't moved in yet, too lazy to clean, the pots are all dirty haha
Netizens exclaim: Looks great, it's so nice to have a terrace!
Treated wood, one of the wooden posts meant to be used as a column has a long crack, needs to be replaced. The wooden flooring dimensions for the wooden platform also don't meet standards, the required 3 cm thickness is only 2.5 cm. Folks, when it comes to renovation, you still have to do it yourself!!
Don't expect others to think of everything for you. Once it's finished, the parts that were done poorly won't be visible, and the parts that are visible can't be changed anymore. Finally made up my mind, and solved the last troublesome issue on the terrace.
