If there are finalised names, of course I'll use them, like Hiu Yan Estate in Sau Mau Ping. However, construction site usually don't have such names, and using road names have problems. A road can be really long, who knows which one? Also, as a map reader, I will wonder what was building at the moment. I think adding public housing into construction sites is totally acceptable. I saw "世運道" and just feels odd, what was "世運道" building? Where exactly is it?
