Thanks for the suggestions, actually I would be doing a film shoot, not a still photography. I guess the closest would be stamford house. Chroma Key wouldn't work for me because of the complexity of the scene and I would still need stock footage of the scene in the end since it's a film shoot.
I went to JooChiat area, as well as many of the areas with shophouses, but a bit too old ah. One of the closer one would be emerald hill. Haha. location is troublesome!!!!
