UPDATE: According to the Daily NK the construction has come to a halt:
The construction of 100,000 homes in Pyongyang has been put on hold due to a lack of cement. According to a Daily NK source, the project is around 40 percent complete.
The year’s aim is to finish 35,000 households out of the total 100,000 planned for construction. Work is due for completion by 2012.
The North Korean authorities had planned to construct 20,000 houses along the railroad from the Ryongseong-district via Seopo in the Hyeongjesan-district to the Ryeokpo-district and 25,000 houses in the center of the city. The schedule for laying the foundations has been set for September this year with plastering and interior works running until the end of the year.
The frame work of the houses, expected to finish by September, have been suspended due to lack of cement and other materials. A source commented that, “It was planned that general construction of frame works would finish in September but exterior construction has been halted due to a lack of materials.”
The North’s authorities have attempted to supply materials through the Sangwon Cement Complex, the Chollima Steel Mill Complex and other factories across the country. Annual production of cement in North Korea amounts to 6.4 million tons, approximately 12 percent of South Korea’s. However this is not enough to fuel general construction of key facilities such as social infrastructure and military facilities.
Large scale power plant constructions such as the Heecheon Power Plant combined with the building of 100,000 houses in Pyongyang have meant the shortage of cement is particularly acute.
Last year the North established the Pyongkeon Development Investment Group, attracting 320 million dollars of foreign capital. According to the plan submitted by the Group, 300,000 tons of cement are needed for foundation work in March alone.
Chosun Shinbo, the publication of the Chongryon (General Association of North Korean Residents in Japan), reported the construction of 35,000 houses was started in September last year. Since then, old houses in the districts have been torn down and neighborhoods rezoned. In March, the foundations of the houses were laid and the exterior frame work was built but construction has made little progress throughout June due to low cement levels.
The 100,000 household construction project in Pyongyang has been led by Jang Sung Taek, Director of the Ministry of Administration of the Workers’ Party, later appointed as the Vice-chairman of the National Defense Commission earlier this year at the Supreme People’s Assembly.
A source reported that, “Jang Sung Taek ordered foreign currency earning organizations to procure cement and that even selling coal should be considered.”
North Korea launched the state project to construct 100,000 houses in Pyongyang as a symbol of completion of the strong and prosperous state as part of a three-year campaign. Additionally, this project has been advertised as an achievement of the successor, Kim Jong Eun. If the plan fails then it will be a blow to the succession. If construction is suspended completely in advance of the Delegates’ Conference, happening in September, the image of Kim Jong Eun could be damaged.
ORIGINAL POST: According to KCNA (October 20, 2009):
General Secretary Kim Jong Il went round newly-built apartment houses in Mansudae Street.
…
Saying that the newly-built apartment houses of new styles in the street are the most modern ones which fully reflect the plan and intention of the Party to provide the people with the best living conditions, he added that those apartment houses in the street serve as a model and standard for building dwelling houses to be used by all the people in a great prosperous and powerful nation.
…
He said that it is necessary to build in Pyongyang modern flats for 100,000 families, houses similar to those apartment houses standing in Mansudae Street, in a matter of a few years as an immediate task.
He expressed great expectation and conviction that all builders of the capital city would create new “Pyongyang Speed” in the era of Songun in the construction of the capital city and usher in “an era of prosperity of Pyongyang” in the new century just as the people created the world-startling “Pyongyang Speed” in the 1950s by building a flat for a family in just 14 minutes true to the Party’s policy of prefabricated construction after the war and as the people in the 1970s and the 1980s opened up “an era of prosperity of Pyongyang” by building many modern streets and great monumental edifices in a matter of 15 years and thus demonstrate once again to the whole world the revolutionary spirit of the service persons and people of the DPRK, successors to the great history and tradition.
The goal of constructing 100,000 flats has been repeated in KCNA since then: December 5, 2009, January 22, 2010, February 6, 2010, March 18, 2010. In KCNA they have been careful not to declare a specific deadline for completion, but (thanks to a reader) in the monthly magazine Korea they have set Kim Il-sung’s 100th birthday in 2012 as the date.
I have blogged about and mapped the construction on Mansudae Street. You can see the inside and outside of these buildings here.
So where will all these flats be located, and what does the construction look like? Below I have posted a GeoEye satellite image from Google Earth which highlights the residential construction areas (in yellow).

So it looks like the majority of the residential construction will be located in Hyongjiesan-kuyok (형제산 구역) in the north and Rakrang-kuyok (락랑 구역) in the south.
According to the June 7, 2010 DPRK evening news, it looks like soldiers are involved in the construction. No surprise there. It is unclear how many are involved. Based on the image below I will let the “professionsals” determine which brigades are involved in the work:

According to the same evening news broadcast, it looks like the workers have reached the second floor of at least one of these construciton areas.
As with the post-explosion reconstruction of Ryongchon (see images here), the North Korean government is tearing down traditional, single-family houses and building “modern” high-rises in their place. At this point the status of the former residents is unclear. Have they been moved into temporary housing (assuming they will get new flats once they are completed) or have they been permanently relocated to make room for the 100,000 lucky families? (This method of residential development reminds me of Ceauşescu’s Romania.)

Looking at the urban geography of the area I get the feeling that Jane Jacobs would be very disappointed.

It seems like the new residents of the northern part of Hyongjiesan will be de facto residents of Sopho even though the railway line makes them separately distinct neighborhoods. Sopho offers the closest train station and market. Residents at the southern end of the Hyongjiesan housing project will need to use a smaller market near the Sopyong Train Repair Factory (See satellite image here) and the West Pyongyang Railway Station. Although the railway line defines the eastern border of Hyongjiesan District as of today there are only two places where commuters may cross over the tracks—at the West Pyognyang and Sopho Railway Stations. The distance between these two railway crossings is 3 miles (4.82 kilometers).
As of now, it appears there is little industry and few schools this far out of the city, so it is probable that most of the residents will be commuting into town. However, none of the new housing is metro accessible. Sopho receives bus service and the West Pyongyang Station receives bus and tram service. However the bus from the West Pyongyang Station to the Sopho Station lies to the east of the new housing and is separated by three miles of railway. Adding more bus stops between the two stations and providing more railway crossings from the east side to the west side of the tracks would be very helpful in reducing the amount of walking residents would need to take. Somehow, I do not think that will happen.
As for the buses, with only one line to service 100,000 families look for them to be crowded. It is possible that a commuter rail-line could easily transport workers to the center of town (like in Hamhung), but that might be wishful thinking at this point.
And finally, although the 100,000 families that do end up living in these homes will theoretically enjoy newer, higher-quality housing, their movements in and out of the buildings can be more easily monitored by inminban (인민반) than those in the single-family homes. In the traditional single-family homes there are multiple avenues to enter and leave the neighborhood, but when everyone uses the same door to enter and leave, residents’ activities can be more easily monitored.
So why not build more high-rises in the center of town where people actually work? These kinds of planning snafus are reflected in most socialist cities and are (unfortunately) predictable. To learn more about the urban economics of planned cities, I recommend not just Jane Jacobs but also “The Urban Dimension of the North Korean Economy: A Speculative Analysis” by Bertrand Renaud. Read his full chapter here. Lots of good stuff from them.
