In its application, co-working can accommodate many startups in one location. Co-working needs to express place identity and identity of community as user. Meanwhile startups, in their effort to express identity of community, need more space control. Only a little research has discussed place identity and identity of community that are specific to co-working. Thus this correlational research aims to identify the relationship of place identity and identity of community in co-working.

The results show that most startup members consider place identity of Koridor Co-working Space to be unique and very unique. From all aspects identity of community and place identity, two pairs of interconnected were found; education with shape and form of building and income with materials. Thus in this position, the hypothesis can be accepted.Keyword: Co-working space, identity of community, place identity Abstrak: Berkembangnya teknologi berkesinambungan dengan munculnya co-working space terutama di Kota Surabaya dengan banyak peminat, yaitu kelompok startup.
