Forest above the city

​By Logan Hanson



Seattle, Washington is experiencing a rapid growth largely due to its burgeoning tech industry. An influx of engineers and computer scientists have flooded into Seattle, which has strained the housing market and caused the cost of living to skyrocket. Seattle typically adresses the housing strain by by razing existing infrastructure and building new, cheaply built “5 over 1’s. By building up with wood, we can apply the code favored 5 over 1 to existing buildings, essentially building “5 residential floors over existing 1.”


The Douglas fir forest that preceded Seattle is long gone. The dense, self sustaining ecosystem was pushed aside to pave way for the city. Now, we have the opportunity to restore the city to its natural functions These wood super-structures must not only house us, but they must feed us, and play an integral role in our water and energy cycles.

Plan B : City Above the City architecture competition 

Metsä Wood challenged architects and students around the world to push the boundaries of modern wood building design in the urban environment. Entrants from 40 countries created their Plan B to urbanisation using wood (Kerto® LVL – laminated veneer lumber) as the main material. The task was to design a wooden extension to an existing urban building. The entries were designed to 69 cities worldwide.
