Urban greening contributes a lot of benefits to the fabric and quality of life in an city environment, and the vertical plane is often the most readily available and underutilised space. Trees are fantastic and as a designer and consulting arborist, I will extol their virtues all day long, but viable root volume is often
NOTE: This article was first written in 2006, so some aspects have been updated to reflect current realities. Biomembranes is a term I’m borrowing from biology (the structure bounding a cell) to describe the outer skin of future self-sustaining buildings. I have stated elsewhere that I believe that for the built environment – and therefore
On my most recent trip to Dubai, I enjoyed walking through some of the new landscapes that emerge as projects are completed. The UAE, along with most regions of the Middle-east has a rather limited palette of plants to work with (although that is growing as new plants are tried). What struck me, however, was how poor the quality
Almost all urban landscapes are contrived and designed, due to their artificial nature and short timescales of development and use. We see increasing use of mature rootballed trees and extensive hard landscape and this is normal for intense inner urban areas; I do get concerned that the increasing complexity of urban planting systems divorce trees particularly
This ASLA (American Society of Landscape Architects) animation does a great job of explaining the need for trees. One minor criticism: the part which shows the trees’ underground root structure shows it way too small; should be at least twice the radius, if not three times. Never mind, worth a watch:
