Simplicity is deceptive. What appears to be sleek and clean lined and refined is highly thought out and designed. Spanish-German architectural design firm YLAB arquitectos (Tobias Laarmann and Yolanda Yuste) have taken a 130m2 apartment in Barcelona's Gothic Quarter and created a space of warmth and elegance, public and private, luxury and practicality. It is as if light and shade, white and earthy, cool and warm, natural surfaces, layers of texture, stone and wood, history and the present have all been distilled into a beautiful home. Deceptively simple. Simply wonderful. Images by Jordi Canosa and Daniela Cavestany.
