What is it?
It’s a concept based on going against the human destruction of the karst topography seen in places such as Vietnam and chine. Those natural movements will stay because the building is constructed into the hills themselves. The blasted shell of the limestone hill will be supported by a steel frame. They hope that the glass and the nature against each other will be seen as a compliment to the monolithic beaty in its natural state and encourage a different way of building.
Why is it cool?
It fit with the micro trend Everything is a Remix, because this building is a mix of nature landscape and modern stuff like glass and metal. Both stuff are totally different of each other.
It also fits with the micro trend Copy Nature, because actually you copy the nature by creating a building in it.
And of course it fits with the mega trend sustainable. The limestone mountains would be destroyed if there wasn’t a solution like this. The mountains don’t get lost for a building, but the mountains are combined with the new building.
