Maria 01

The world's first KEKO building is now open for testing purposes

Maria 01, the world’s first KEKO site, is now open for testing and experimenting with KEKO platform and APIs. Maria 01 is a multi-office environment located in Helsinki, making it a great site for office-related service development.

KEKO members have the opportunity to develop new value-adding office solutions there, which can create sustainable business potential and empower property owners, tenants, or end-users, using the wide range of sensors and tools built-in.

NOTE: As the KEKO research project is ending at the end of 2021, APIs will not be updated.
