Portland high-rise to get 250-foot-tall trellises
PORTLAND, Ore. – They haven't figured out yet how to get the pruning
done, but architects and federal officials plan one of the world's most
extensive vertical gardens in downtown — what amounts to a series of 250-foot-tall trellises designed to shade the west side of an 18-story office building
The work is part of a $135 million remodeling, with most of the money
from federal stimulus funds. It is the largest single stimulus project
announced so far in Oregon. The U.S. General Services Administration says its goal is to create a "landmark high-performance building."
