Once I discussed with one Indonesian hi-rank developer official, and he said that IF those cities are integrated to each other, and located in one large area, and named under one name, the size of it will be bigger than Singapore and Kuala Lumpur combined. Well, I have no intention to really measure the size of each city, since they are scarcely located.
There's a new city being developed in the east of Jakarta city, called Summarecon Bekasi. Of the 250 hectare of land available, 35 percent will be allocated as commercial area. The developer will build 16 clusters whereby each consists of 6 to 7 hectares with 200 to 300 houses. In addition, there will also be apartments, shopping mall: Sumarecon Mall Bekasi, trade center, office park, shopping houses, modern fresh market, as well as an artificial lake which serves as retention basin.
Other city being developed in the southeast of Jakarta is Harvest City, it presents 1,050 hectare of township, the largest in East Cibubur, Bogor.
In Addition to those two, there are many more being developed in West Java, and now you can start imagine how big the modern and elite city is when they are combined in one integrated area.
