Some of the units feature glass block windows. My unit will have a wall of my dining room with a glass block window. So that is meant when they mention being backlit, but I doubt all of the glass block walls will be backlit especially when it is a solid wall. The photo of the mockup above shows this nicely.
As for the landscaping, there have been extensive studies on the micro-climate (light, wind, precipitation, etc.) of these planters and where they are located and oriented on the building to help decide on the ideal vegetation. The vegetation selected is unique depending on its location, soil depth, etc. There are 8 different types of vines used on the building of varying colours, foliage, flowers, etc. to create a dynamic lush appearance while ensuring it is sustainable and easier to maintain.
I already know the types of plants that will be planted on my terraces, including one of them which will have a flowering dogwood tree that I am excited to have in my backyard in the sky!
Looking forward to your pics once completed.
