Hong Kong is one of the most expensive and densely populated cities on Earth. With over 7 million people living on an island just 1,102 square km is size, the population is constantly struggling for space. Like other major cities around the world, Hong Kong is in the midst of an affordable housing crisis. The strict limitations on space mean that there is a capped supply of housing on the island. A limited supply, paired with an ever-growing demand, has caused Hong Kong housing prices to skyrocket.

Helping to ease this problem The Hong Kong Pixel Home architecture competition participants are tasked to utilize the Hong Kong's last remaining pixel-sized spots of the land to design affordable residential buildings that will help alleviate the city’s housing crisis and support its low and middle class community struggle for accommodation.

There is no set competition site, but participants are limited to a single area of just 100 m2, a size that would be considered problematic for high-level construction in any city in the world other than Hong Kong – the land of tiny footprint skyscrapers!

Design a pilot-phase concept for affordable housing within Hong Kong, which can be easily rolled out to increase the capacity of housing stock and is minimal in its use of land and materials.

No minimum size or amount of residential units per block is defined. Proposals should be flexible enough to adopt to various sizes with multiple inhabitant capacity requirements.

Designs for the Hong Kong Pixel Homes should be versatile to adapt to different locations across the city and be flexible, allowing adjustments to be made in order to suit different residential capacity requirements.
