P PLUS arhitekti is an architectural practice based in Ljubljana, Slovenia. Our work spans different scales and typologies, with a strong focus on context, atmosphere, and long-term usability.

We believe that architecture is not about making a statement, but about making sense—of place, light, and human experience. Each project grows from careful observation and evolves through dialogue, drawing on the specific conditions and potentials of each site.

We approach every assignment with curiosity and precision. Whether designing a new building, adapting an existing structure, or rethinking the use of space, we seek clarity in form, material, and intention.

The office was founded by Primož Boršič, and today works as a collaborative team that values responsibility, resilience, and architectural quality above trends or spectacle. We believe multidisciplinary design and cooperation of different professionals leads to better results, in every aspect.

We work on projects across Slovenia and are open to international collaborations.
