Before he opened FR-EE, his very own architecture practice in Mexico in 2000, Fernando Romero was a protégé of Dutch master architect Rem Koolhas at OMA in Rotterdam. Since then he has become one of Mexico’s most in-demand architects, and for the very first time Romero is opening his doors to show us his own home. Since 2010, he, his wife and his 5 children have been living in the residence originally designed in 1955 by local architect Francisco Artigas.
