napp studio’s ‘mutant yard’ proposal introduces an organic and flexible architectural system based on beijing’s hutong lifestyle. hutongs are a type of narrow streets or alleys found predominantly in beijing, which are formed in lines of siheyuan, traditional courtyard residences. the firm has proposed a scheme which would incorporate this traditional structure with the surrounding neighbourhood and various programmatic situations.

napp studio has proposed a contemporary version of the siheyuan structure, which is able to sit within a tiny (33 sq.m) plot, housed within a single central courtyard. this feature opens out onto the street, encouraging interaction between neighbours and visitors. the building is not a replica of the traditional grey-brick pitched roof, but a rennovation which preserves traces of historic details, injecting new energy into the old urban fabric.
