According to a URA Nov/Dec newsletter, this row of shophouses along Jalan Jurong Kechil were used as comfort houses during the 2nd World War. It said that there were plans to conserve this row. Currently, you can find a mix of shops there, from spas, clinics, to shops selling paint. The lower building (in the upper picture, to the left) was a modern development, built in 1992. Picture taken Feb, 2014.
J K Building at Jalan Jurong Kechild -- a relatively new commercial development. This is just my conjecture -- it probably stands on where a row of prewar shophouses used to be (see PictureSG). Next door, some development is literally "under wraps". Further down the road, towards Toh Tuck Road, The Hillford has "choped" the land -- "Singapore's first retirement resort".
