Clip-on retrofit of cities

Vanessa Keith has a provocative article about urban reforestation. Rather than focus on new buildings, a small percentage of any city, Keith proposes rebuilding through a “clip-on” to existing urban structures and infrastructures. Keith considers roofs, walls, and highways as valuable surfaces that increase by factors of two (for in-fill structures) or six (for free standing structures) the total surface area of a city.

Her clip-on ideas include green roofs, roof ponds, vertical gardening, waterfalls for cooling and power generation, wind bands, and more urban trees. I like how she connects urban solutions with rural deforestation, and considers government incentives and the potential role of large developers and community groups in creating a demonstration block in New York City.

Tokyo University Sanshiro-ike garden in fall

On a beautiful warm November day, I discovered Tokyo University’s Sanshiro-ike garden. I had a few moments before a meeting, and saw on the campus map that there was a central garden on the main campus. I had assumed it would be a formal garden.

I was very surprised to descend a small hillside and encounter this natural looking pond. Looking in all directions, one sees only trees, water and sky, despite the compact size of the garden. Even on a warm weekend day with early fall foliage, few visitors were there. I was enchanted by the incredibly natural and removed-from-the-city feeling in this garden inside central Tokyo and Japan’s most famous university.

It takes a lot of artifice to make a city garden look so natural. The waterfall is amazing.

Skylight waterfall

This skylight waterfall in Roppongi’s Midtown provides a cool feeling on a hot summer day, and disguises the massive scale of the office tower above.
