Hong Kong is one of the most densely populated areas in the world despite its low birth rate and land reclamation.
With 6.3 people per square metre of land, high-rise living is imperative. But even here space is limited.
Apartment sizes average 600 sqft, often with large families squeezed in together.
Add to this Hongkongers desire to shop and with space so scarce and flats so small where do they put everything?
While many local households struggle with storage space, their counterparts in Europe, Australia and the United States, have long learnt to store excess goods away from home.
In the past decade several local entrepreneurs have introduced these storage solutions to Hong Kong, and now the local storage sector has between 70 and 80 players.
