Atelier Ad Hoc is a Bucharest-based architecture practice founded by Daria Oancea and George Marinescu. Operating both as an architectural studio and a non-profit organisation, the practice explores alternative ways of responding to current social and ecological conditions. Positioned in-between architecture, design, and cultural practice, the studio engages with a wide range of projects, including built work, socially engaged initiatives and research-based projects.

Their works were presented at La Casa de la Arquitectura Madrid, Aedes Berlin, World Expo Osaka, BASE Milano, WantedDesign New York, BETA – Timișoara Architecture Biennial and Romanian Design Week. Their projects have received distinctions from the European Prize for Urban Public Space, the Romanian Biennale of Architecture, the Bucharest Architecture Annual and BETA – Timișoara Architecture Biennial.

In 2026 they are part of the team realizing the Romanian Pavilion at the 61st International Art Exhibition of La Biennale di Venezia, contributing to the spatial and architectural development of the project ‘Black Seas – Scores for the Sonic Eye’ by artists Anca Benera and Arnold Estefán.
