Hidden on the top floor of a quiet street in Mexico City is architect Alex's lovely apartment, which was designed by himself and is actually the first passive house in all of Latin America. The aesthetic is both charming and industrial: exposed structure, OSB, and DIY elements give it a fun and playful atmosphere. The best part is the roof deck which almost as large as the apartment and is filled with plants and light, enjoyable at any time of the day or night. I want to live here. Highly recommended.
