ONOFFICE Environmental Architecture is an architecture firm based in Athens, Greece, established to deliver projects from concept to construction across a range of scales and uses. The studio operates in fields such as housing, urban design, private development planning, interior design, educational facilities, and the restoration of open spaces. Its work is guided by a focus on environmentally responsible design, seeking to incorporate sustainable principles from the earliest planning stages onward.
The clientele of ONOFFICE spans public sector bodies, municipal and government agencies, private developers, corporations, and individual clients. The firm’s organizational structure relies on the expertise of its core principals, collaborators, and consultants, enabling it to provide comprehensive design, presentation, and communication services.
A notable recent milestone for the firm is its first prize in the competition for the restoration and redevelopment of the historic Germanina Estate in Gerospikou, Cyprus. Their winning proposal transforms an abandoned 19th-century agricultural complex into a botanical park featuring a mix of new and restored buildings, including a museum, a wellness center, and public amenities. The design integrates the estate’s built heritage with contemporary uses while emphasizing long-term landscape conservation. The project’s spatial program includes cultural, educational, and recreational spaces organized around the estate’s courtyard, with new architecture subtly embedded in the land.
Projects showcased by the firm include residential developments in locations like Chalkidiki and Epidaurus and commercial projects such as a logistics center in Aspropyrgos. ONOFFICE's practice demonstrates ongoing engagement with site-sensitive, energy-efficient design and adaptive reuse.
