The Ambassador is slowly turning into a giant treehouse of sorts, a post-apocalyptic abode of the Swiss family Robinson. Trees fill the courtyard and obstruct windows. Seven stories up, saplings sprout from the floorboards and carpeting. The lobby is tinged emerald with the light filtering through the foliage outside.
Treetops stand in for a ruined wall on the fourth floor.
Finally, walls and ceiling give way to sky on the seventh floor.
