Maybe this ad on the Habitat Property website might answer part of your question, selling not just the land but also the Ding right to build a house:

Beachfront Site - Unique Opportunity

• Unique opportunity to purchase a beach front lot
• Planning permission for a 3 storey house totaling 2100 sq ft
• Build a 2/3 bedroom house
• Mo Tat Beach, Lamma Island
• Ideal location for home or holiday house
• Rare beach front location
• Very unique
• Sole agent

Only $11 million for just the empty plot of land... in Mo Tat Wan!

This might be the first time I've seen a Ding right (Village House planning permission) so publicy advertised for sale as this might technically be illegal, but very wide-spread in the new Territories and Outlying Islands.
This is right besides The Bay restaurant in Mo Tat Wan. I might have to have another little bike ride around South Lamma for a closer look.
