That's nice but that is hardly a skyscraper. By the look of it the building is around 15 floors high... let's say around 40m high. The author was talking about putting trees at 500feet in the air, that's 152m... considerably more.

500 feet up is really not that much considering trees are just fine over two miles (10,560ft) above sea level. Mountains generally do have a tree line, but most buildings are well below what the local tree line would be as most city's are fairly close to sea level.

Highest tree line in the world is at 5200m[1]. Don't see why trees couldn't cope with 150m (yes, I know building != mountain, but still). [1] - http://en.wikipedia.org/wiki/Tree_line#Alpine_tree_lines http://en.wikipedia.org/wiki/Tree_line#Alpine_tree_lines

  What is relevant here is height above the ground, as the various forces that he describes are a facet of the ground effect (or lack of ground effect). e.g. You would find the top of the CN tower an endlessly windy, environmentally unfriendly place. Yet standing on the street in Madrid you are just as high and suffer none of the same effects.

I don't see height as being the issue, I beleive this building is around 50m-60m high. This building is in front of the ocean and gets a fair share of both wind, salt and the occasional snow storm (it's in Vancouver). It was lifted in place using a crane and since it's a large oak tree a system must have been been put into place to deal with the extensive amount of roots ( I'm not sure how long it's been there but at least 15+ years). Here is Google maps street veiw, it has a better perspective: https://maps.google.ca/maps?q=1919++Beach,+Vancouver,+BC,+CANADA+(Eugenia+Place)&ll=49.28911,-123.14293&spn=0.001912,0.003001&hnear=1919+Beach+Ave,+Vancouver,+British+Columbia+V6G+1Z2&t=h&z=19 https://maps.google.ca/maps?q=1919++Beach,+Vancouver,+BC,+CA... tl;dr Trees are not pussies, this is all about money (installation and maintenance).

Your estimate is very good! Here is the building [1] and I estimate 16 stories. Roughly 160 feet or 50 meters.
