Freddy Mamani Silvestre (born 1 November 1971) is a Bolivian self-taught architect[1] noted for his development of the Neo-Andean architectural style.

[2] His work is most associated with the city of El Alto and with the new social class of upwardly mobile indigenous Bolivians.

He had dreams of becoming an architect, but his work schedule would not permit him to attend whatever classes available in his local universities.

The Tiwanacotas used a language of civilization in their forms: textiles, ceramics, and architectural ruins.

Mamani uses the Andean cross, the diagonal juxtaposition of the planes, the duplicity, the repetition, the circle, which makes all this a stylisation theme, that is its source.
