It must feel like a jungle in this Shinjuku Gyoen-mae apartment balcony. The sheer coverage, in height and width, is impressive. Below is what the balcony looks like in context.
Spurred by the energy crisis post-Fukushima, there’s been a notable increase in the number of mid-rise office and retail buildings with green walls. In an over-built city, vertical surfaces are the largest potential area for gardening, farming, and habitat creation.
Tokyo has far more vertical surfaces than roof areas, and we are only at the very beginning of creating an urban forest.
I have been following this topic for a while, and have watched this idea spread from notable public spaces like Suginami’s ward office (world’s largest green curtain) to apartment balconies, flower shops, and now commercial and retail spaces. This wide distribution across Tokyo and across building types is very exciting to see.
Some questions I have include:
- What types of plants can be grown vertically and for what functions: aesthetics, habitat, scent, seasonal change, food?
- How can green walls enhance innovative architecture and place-making?
- How can vertical and roof gardens connect buildings, neighbors, and wildlife?
- What is the impact on heat island effect, global competitiveness, and quality of life?
The answers will come from experimentation and diffusion. The photos, from top to bottom, are four green walls I’ve recently seen:
1. Hasegawa Green Building in Shiba Koen
2. Office mid-rise in Shinjuku Gyoen-mae (2 photos). The company that created and maintains this green wall is called Ishikatsu Exterior (石勝イクステリア).
3. Oimachi retail building near station.
4. Daimon office building.
