STUDIO KAEFI

Profile

studio kaefi is a Berlin-based architecture practice that works with what exists — spatially, socially, and materially. Its aesthetic emerges from context and constraint, expressed through simple, direct interventions. Its work unfolds through collaboration, shaped in close exchange with communities, artists, and young people.
