A sign in the North Korean capital, Pyongyang, touts the coming development of high-rise, high-tech apartments that include card-access, high-speed elevators, NKNews.org reports. The sign, with a rendering of a sleek-looking tower that appears to be about 30 stories tall, says the building will feature 180-m2 units and will be built to the "highest-quality" construction standards. Observers said the elevator technology likely came from China, noting that the card-access security feature is new for buildings in North Korea. The sign also says that solar energy will be utilized in the building. The location is in the central sector of Pyongyang, an area popular among government officials.
