Stackable apartments. Um...what?

Article link: Stackable apartments. Um...what?

This article is about a Sky Village, whose "main concept is centered around a system of individual units that can be stacked in various configurations to maximize available space and allow for easy structural changes in response to market demand," and goes on to explain:

If a retailer wants more space or if the village needs more office or residential units, "pixels" can be easily added to reconfigure the structure. Each pixel is about 60 sq meters and they all are arranged around a central core. The inclusion of retail, restaurants, and offices in a residential development allows people the ability to live where they work and play, making this in a true village, albeit a vertical one.

Though the article is a bit skeptical about how this will work, I'm excited about the idea of it! It sounds very futuristic, and appealing. Even the renderings look like we're living in the future.
