Guillen Esteras is an architectural practice founded by Yannick Guillen and Francisco Esteras. We started working together in 2018 on competitions for public projects, initially in Spain, but later in Germany, Switzerland and across Europe. Our focus continues to be on public and cultural works, along with selected private commissions.

Our architecture is informed by a strong sense of place. Drawing on context and circumstance we try to find a conceptual and practical solution for each project. We hope to create buildings which respond to their environment, have a clear constructive logic and feel intuitive to inhabit.  

We currently combine our practice with teaching at the Kingston University London and Technische Universität Braunschweig.
