The founders

Design eye. Engineering discipline.

Rocio is a career interior designer; Jorge an engineer. Every drawing passes both.

Rocio Perez, co-founder of D’Hierro

Rocio · Design

Proportion and finish.

A career interior designer, Rocio sets the scale of the steel against the room, the rhythm of the glass and the finish beside stone and wood: the decisions a client lives with every day.

Jorge Perez, co-founder of D’Hierro

Jorge · Engineering

Structure and fit.

With an engineering background, Jorge carries each opening from proportion and structure through fabrication and hardware to the final field adjustment, so what is drawn can be built and performs once it is.
