Peter Zumthor, Swiss Architect & Winner of the 2009 Pritzker Prize & 2013 RIBA Royal Gold Medal, says about concept development: "Designing is a matter of concentration. You go deep on what you want to do. It’s about intensive research. The concentration is warm and intimate and like the fire inside the earth – intense but not distorted. You can go to a piece, really feel it in your heart. It’s a beautiful feeling.”
