Here is a location with a bit of a story behind it (which is why it has taken so long to find). The problem was this - a seaside location with calm water (so sheltered from the open sea), with a large kiln, concrete block and small abandoned hut. I looked everywhere for a long time and could not find anything that matched. I gave up - it could have been anywhere along HK's vast 800km coastline.
Anyway, it turns out (with help from some shots from another film from Daniel of Hong Kong on Film) that this location is the gap between Kau Sai Chau and Jin Islands in Port Shelter.
I've never been here myself but know that there is a small restaurant here that is popular with boaters (because there is no way else to get there) but the shots from Panoramio suggest that the large chimney/kiln has been demolished (I suspect this was an artifact related to the nearby Hung Shing temple) as has the large concrete blockhouse. But there does seem to still be a small abandoned hut there (which I am sure you will be able to see when Dan puts up his own post on this location). The whole shoreline has been concreted and smoothed out, but the background remains the same. If you are wondering about the exact location here is a Googlegrab.
Kau Sai Chau to the north (this island is popular because it contains HK's only public golf course - but you still need to catch a boat to get there) and this area is on its southernmost part. The small cluster of squares to the left of the gap is a fish culture farm - quite popular here in HK for raising fish for restaurants and at one time blamed for the shark attacks that occurred in the early 90's because the fish food was thought to attract the sharks!
