Competition: we're giving readers the chance to win one of five graphic prints that depict iconic buildings by architects including Oscar Niemeyer, Zaha Hadid and Álvaro Siza.

Congratulations to the winners! Oliver Hans from Germany, Ondřej Švancara from the Czech Republic, Gergely Kenéz from Hungary, Alvaro Araico from Mexico and Babita Ram from the UK all won an illustration by André Chiote.

Portugese illustrator André Chiote created the series of architectural illustrations by simplifying images of recognisable buildings to emphasise their form and shadow.

Designs include MAC Niterói by Oscar Niemeyer, Fundação Iberê Camargo by Álvaro Siza, Mercedes Benz Museum by UNStudio, Museum of Islamic Art by I.M. Pei, Ningbo Museum by Wang Shu, Riverside Museum by Zaha Hadid, Whitney Museum by Marcel Breuer, MUSAC by Mansilla+Tuñón and Casa das Histórias Paula Rego by Eduardo Souto Moura.

The minimal graphics are slightly mottled and executed in faded colours to give a vintage feel.

Each poster is printed with the building's name and architect in typography chosen to compliment individual designs.

The posters to be won are 30 centimetres wide by 42 centimetres high, though they also come as 50 by 70 centimetre prints. Both sizes are available from the artist's Cargo Collective online shop.

This competition is now closed.

Five winners will be selected at random and notified by email. Winners’ names will be published in a future edition of our Dezeen Mail newsletter and at the top of this page. Dezeen competitions are international and entries are accepted from readers in any country.
