EI Hogar D. Antonio Melian established in 1910 a building society that issued mortgages called "EI Hogar Filipino." Four years later, in 1904, the four story building of the company, designed and constructed by Irureta-Goyena, was inaugurated on the corner of Juan Luna in Binondo facing the Pasig River. Designed with touches of the French Beaux Arts style, it has an enriched entablature topped with an attic story and a flat roof. It looks deceptively sedate until one enters its discreet entranceway. The double door leads to a center courtyard with balustraded corridors connected by an exuberant Art Nouveau staircase situated along the end of a passageway. With bronze griffins for newel posts and gilt swirling around initialed medallions, the interior speaks of a bygone elegance.
