I guess very small is expensive..
Over the weekend a tiny (286sqft) studio flat in Hong Kong’s North Point district has gone on sale for more than HK$10 million (US$1.27 million), on the site of a former public housing (council) estate. A 181 sq ft studio flat at Novum Point, also in North Point, last month changed hands for HK5.87 million (US$ 748k). then add the expensive serivce fee per month and utilities I guess you be operating in the minus area.
