Unidentified Facility In Southern Laos

Was perusing imagery where I monitored NVN forces infiltrating through Laos (the Ho Chi Minh trail) to South Vietnam in 1967/68, and came across this strange facility being constructed in the middle of nowhere. Any Ideas?

 

check GE layers -photo layer in this case- every time before posting:

based on titles of Panoramio shots this is "Ban Keng Kien", "New Camper Town" or "new village of Cu Chi" or "Kaleum Mai" under construction. Another panoramio shot title says this is "New Lost City" and another "new city of Grapevine". 
however some confusion can be detected around (Google transated) settlement names it seems quite clear, that this is some construction works of a new (group of) settlement(s). (other photo title mentions "6 new cities")

small, pretty houses, roads to schools and other, brand new social, governmental buildings can be seen on panoramio images from 2015.
(also three cool off-road photos on the dirtroads to S!)

BingMap has the same old imagery from 2014, however using GE TimeSlider tool one can see that there were nothing in 2006 except some patches of clear-cuts.

it is situated in Administrative area of Kaleum and this is said to be construcion works of a new district capital (click link to article quoted below):

New Kaleum district capital progressing as planned

The project to relocate the municipal capital of Kaleum district, Xekong province is now some 70 percent complete.

This project commenced in 2012 and the authorities are expecting it to be complete in 2015.

During the wet season work has been difficult but the contractor is confident that all works will be completed according to the plan.

The authorities in Xekong province held a meeting to discuss this project last Tuesday in Vientiane.

It was presided over by Xekong Provincial Governor Mr Khampheuy Bouddavieng and officials from other organisations.

During the meeting Deputy Provincial Governor of Xekong province Mr Lieng Khamphoun said Kaleum district capital town had to be relocated because previously administration was difficult as it was in a low lying area and flooded on many occasions.

The project to build a new capital town has eleven priority works including the construction of public offices, residential areas, roads, electricity, water supply and allocation of land areas for local people to earn a living.

The existing town is also located in an area that will be affected by a hydropower project so the government has decided to relocate the town. The new site is about 32 km away from the existing one.

Phonesak Group will invest 930 billion kip to build the new administration office and will be paid back by the government after it is completed in 2015.
