This is the building where I work from most days. It is a combination of Pink stone and Pink mirrored glass and is pretty iconic in the Portland skyline.
I've always felt a little odd trying to photograph it. Perhaps maily because it has been photographed so well so many times.
It was the tallest for a few years, hasn't been for awhile now. Luckily the new owner of that title is on the other end of downtown and Big Pink stands on its own on the Northern end and still appears to be the tallest.
