The LEGO set 41757 surprised so many builders because it is truly a city building instead of a Friends one. While some AFOLs obtain two copies of this (and I did too) to close off its original open-back design, I took a slightly different path by also raising the entire garden up.
Now, sitting on a brick structure, the garden has more space to showcase more plants and flowers. The giant flowers having foul odor are kept in the glass boxes with ventilation, and there is a small janitor's room in the corner for taking care the plants with necessary tools.
I hide the staircase in the back so that the front elevation is not interrupted and everyone can appreciate the columns and arches flowing from the bottom to the top. The Botanical City Garden is open all day and will be a calm spot for city dwellers around!
