Afonso spent his first two years of his career (2003-2004) working at Manuel Aires Mateus, developing several projects and gaining work experience.

In 2004 Afonso joined as managing partner the architectural studio Chp Arquitectos where he worked as lead designer and project coordinator for 12 years.

In 2016 Afonso founded Almeida Fernandes Arquitectura, where he remains to this date.

Afonso’s professional scope ranges from project design and coordination, urban refurbishment, design and planning, project management and project consultant as a coordinator in various building due diligences. His work experience in Lisbon for the past 14 years allows for a strong knowledge of how the city has evolved, grown and transformed, contributing to this transformation through his designs as author and co-author of several houses, buildings, allotments and city plazas.

Recently, he has created a association dedicated to bringing architectural design to the poor.  Associação CAuSA has refurbished more than 30 houses in partnership with Just a Change and is currently implementing a project of 33 agricultural shelters for subsistence farmers in the regions of Arganil, Castanheira de Pera and Oleiros.
