Edifício Franjinhas, Modernist office building in Santo António, Lisbon, Portugal

Edifício Franjinhas is a building at the corner of Rua Braamcamp 9 and Rua Castilho in Lisbon, built between 1966 and 1969 to designs by Nuno Teotónio Pereira and João Braula Reis. Its facades are hung with prefabricated reinforced-concrete plates made on site, which act as sunshades and give the building its fringed look. The lower floors hold shops around a gallery, with a mezzanine snack-bar opening onto continuous balconies; six office floors rise above, topped by restaurant and administration levels.

Architects Nuno Teotónio Pereira and João Braula Reis designed this structure in the 1960s as a response to new ideas in building. It won the Valmor Prize in 1971, an important award for Portuguese architecture.

The name Franjinhas refers to the fringe-like concrete plates hanging on the facade as sun protection. Artist Eduardo Nery designed the calçada-mosaico pavement of the lower shopping gallery, using black-and-white circles that guide visitors through the space.

The building is easy to reach by several public transit options and sits at a busy street corner in the city center. The ground floor galleries are accessible during normal business hours.

The name Franjinhas refers to the fringe-like precast concrete plates hung on the office floors, made in the construction site's own workshop. These plates were studied on a model beforehand: they create a walkable intermediate space, extend the interior past the glazing, even out daylight through the year and cut direct sun and heat.
