What about hemp, bamboo and coconut fiber? I would guess that incorporating these in the right ways would greatly improve both the strength and environmental impact (as in how good it is).
What about longevity? Weathering and other concerns. I would have some concern over structural members that might fail at a given time later on. Much less how a wooden skyscraper might perform in high wind.
Not saying it can't be done. I just want to make sure it's safe.
@VoiceofReason i would think that wood probably has better longevity than concrete, which is susceptible to concrete cancer. There are plenty of wooden buildings around that are 400+ years old, i don't know how safe our concrete structures will be after half that time.

A great technical leap, just need to lower the weight/strength ratio
re; inchiki It is not just wood there is also the glue.
There are concrete structures that the Romans built that are still in use. The rebar on the other hand might be a problem.

You may want to check this, made using X-Lam technology (wood only), which resisted to many repeated huge seisimc tests without significant damages:

Ahhh..does the word TERMITE mean anything to you guys....?

Rebar made from basalt is immune to rust, and a barrier to "concrete cancer". Basalt is also as fireproof as asbestos, without the environmental concerns, and can be used as an alternative to fiberglass insulation. Panels incorporating basalt are inherently fireproof and durable, so it seems a natural partner to wood structures.

Some 55 years ago Mies noted that highrises were more economical to build than townhouses. That actually means that they provided HUGELY LESS ENERGY to build.
And the problem of acoustic privacy remains but has now been solved with the availability of AAC.
The ledger beams appear to be too shallow.
The Design and renderings are beautiful but, in reality, this is a specious effort.
After building a three story house in Colorado, I was impressed by the compression forces of the mostly wooden structure. Sheetrock cracked which we had to repair constantly as the house "settled in". After 10 years, I bet the house compressed down about from an eighth to a quarter of an inch. "No, I did not take a height reading at the initial frame out. Wish I had."
I have read of such things on huge log homes, where there are mechanical jacks to set the home level. I can only imagine at the amount of "settle in" on such a tall wooden structure.
