the regeneration of hutong courtyard houses is a popular and ongoing concept throughout beijing. over the past year, people’s architecture office (PAO) has expanded their ‘courtyard plugin project’ from an experimental prototype, originally featured by designboom last year, to a systematic solution applied across hutong areas. the program of low-cost and imaginative solutions revive derelict properties, as well as homes of local residents that desire a higher standard of living without relocating.

for beijing design week 2015, PAO presents a series of nine ‘plugins’ for the historic dashilar district. these interventions range from an accordion-style construction that gives residents a private bathing space, to a system of sliding doors that offers a more intimate connection between the interior dwelling and the courtyard community. each of the projects simultaneously integrate with the existing urban fabric and improve the quality of living, energy efficiency and space within the home.

this intervention allows bi-folding doors to lift and form a shelter for the outdoor courtyard

people’s architecture office has developed a prefabricated composite panel that incorporates structural integrity, insulation, wiring, plumbing, windows, doors, interior and exterior finishes into one molded part. these sheets are lightweight, easy to maneuver, and inexpensive to ship, snapping and locking together with a single hex wrench. the entire plugin structure can be assembled by a few people in just one day, requiring no special skills or training. the result is a sealed and insulated interior that reduces energy costs by one third. the system of ‘plugging-in’ is half the cost of renovation, and about a fifth of the cost of building an entirely new courtyard house.

the interior space allows enough room for multiple people to meet

the new plugins include ones built for local residents as well as gallery, live/work and bed and breakfast uses. a diverse set of fabricated structures have been built with a range of features: mezzanines and expandable, accordion-style rooms add precious space to small areas; walls open by sliding, tilting outwards or upwards, providing a more intimate connection between the interior dwelling and the courtyard community space; options for handling sewage include septic tanks that expel grey water and waterless composting toilets; kitchens and bathrooms can be added for residential use, while more basic versions can be used as work space.

‘vast areas in china are still being torn down without a second thought,’ the team at PAO explain. ‘people are forced from their homes, social ties of tight-knit communities are cut, and layers of a tumultuous history are lost. the courtyard house plugin is a shining alter native to short term profit driven development through long term, socially-driven development. individuals can create  their own distributed energy efficient infrastructure. upgrading living standards does not require tearing anything down. and micro investment by many individuals can be just as or even  more effective than massive investment from a few people.’
