Sky City gets go ahead

In a few speeches I’ve given recently, I’ve talked about the incredible impact Broad Group’s system of remanufacturing skyscrapers and building them for a fraction of the cost will have on our skylines, urban planning, and ability to all move to the core downtowns of major cities. Well, they just got the go ahead to build their biggest building yet. It’s going to be the tallest in the world, and they’re going to build it in 6 months. It starts next month.

“The building is to cost $628 million and have 11 million square feet of space inside, which is about $60 per square foot. A 1000 square foot apartment would cost the developer about $60,000 and might sell for about $100,000. This would lower the cost of living in megacities like Shanghai, Changsha or New York. The lower cost versus $300 to 1000 per square foot for buildings like the Trump Tower Chicago or Freedom tower means that skyscrapers could hold not just expensive offices but also regular apartments, grocery stores, hospitals, schools and other regular applications. The low cost enables a city inside a skyscraper and not just high end offices, luxury apartments and high end restaurants.”

(Via 220 Story Sky City Gets go ahead to start construction in June 2013, so it should complete by the end of 2013.)

I really think this is one of the most underlooked, game changing developments of the last few decades we’re about to see.

1) more people in cities increases creativity (due to simple random exchange of ideas, it’s a known effect), decreases infrastructure needs on a per capita basis.

2) cities are greener

3) the invention of steel skyscrapers, and then elevators, in many places changed the landscape and economic impact and power of cities. This is another major accelerant for cities.

Take a look at the city before the invention of the elevator and after. Or when they moved from brick to steel.

Then make a similar jump for this new form of manufacturing.

Concrete Cloth, just add water to harden into concrete

Douglas Fasching on twitter pointed out this video of concrete cloth, a concept I’d never come across before and was fascinated by:

After watching that video I went hunting online, and found where you can buy just straight rolls of concrete cloth:

“Concrete Cloth (CC) is a flexible cement impregnated fabric that hardens on hydration to form a thin, durable water proof and fire proof concrete layer.

Essentially, it’s concrete on a roll Just Add Water.”
