Four readers will each receive three posters, created by graphic designer Peter Chadwick as part of his wider project This Brutal House, which uses graphic design to explore popular brutalist housing projects. Chadwick describes it as "architecture with a graphic design lense".

For this poster series, the London-based designer has selected complexes built in Italy during the 1960s and 70s, often as part of government-mandated programmes to rebuild the country and help to accommodate people after the destruction caused during the second world war.

Each print features a project located in a different Italian city, with places including Bologna, Busto Arsizio, Florence, Genova, Livorno, Milan, Naples, Rome and Trieste.

For Milan, Chadwick chose a building that Italian architect Aldo Rossi completed in 1972 as part of the Gallaratese Quarter, featuring a set of identical square windows atop a pillared construction. An image of Japanese architect Kenzo Tange's Fiera District, built in 1970, adorns the Bologna poster.

Photographs of the developments are reduced to black and white, and surrounding nature and structures are removed. The architectural images are then overlaid with colourful designs that make the structures pop against the white backgrounds.

Each has two bold colours in various shapes, from large circles and orthogonal lines to more organic curving designs. The title Brutalismo is placed in the top left corner, while the name of the city in Italian is set to the top right.

The designer said his influence for the layout came from a series of minimal posters that graphic designers Tom Geismar and Ivan Chermayeff, co-founders of New York-based firm Chermayeff & Geismar & Haviv, created for American airline Pan Am in the 1970s.

"My dad was a managing director of a travel agency in Middlesbrough, my hometown, in the 1970s," said Chadwick. "The Pan Am posters designed by Chermayeff and Geismar that used to adorn his office walls inspired this poster series, which is part of my ongoing self-initiated projects for my This Brutal House collection."

The Rome poster, which bears Italian architect Mario Fiorentino's Corviale complex, is decorated with a symmetrical mustard yellow and red graphic.

Another poster has pops of soft green and pomegranate, overlaying a black and white image of the Technical College in Busto Arsizio, in northern Italy. The swooping design was completed in 1964 by Italian architects Enrico Castiglioni and Carlo Fontana.

To represent the port city of Genoa in northwest Italy, Chadwick chose Le Lavatrici by architect Aldo Luigi Rizzo. The project features rounded glass fronts, giving it its nickname "the washing machines". Teal and sky blue cover most of the poster, emphasising the building's bulky and impressive scale, and its connection with water.

A tiered structure for the Vele di Scampia by Italian architect Franz di Salvo is in Napoli. One large teal circle offsets the image, with yellow blocks flanking either side.

Italian architect Leonardo Ricci's La Nave Apartments is the centrepiece of the Firenze poster. Pale colours help to soften the building's stark forms, with one large lavender-toned dot and another yellow spot alongside a larger pattern.

A tall residential building with purple and blue designs forms the poster for Livorno, a port city on the Tuscan coast. Italian architect Giovanni Michelucci built the tower as part of the Piazza Matteotti.

Other designs include the northern city of Trieste near Slovenia, featuring a building completed by Italian architect Carlo Celli, and part of the Rozzol Melara complex – a housing prototype on the far corner of the city.

Brutalism was a prominent architectural style for housing complexes around the world in the 1960s and 70s. Le Corbusier's Unité d'Habitation in Marseille and Moshe Safdie's Habitat 67 in Montreal are other iconic examples of brutalist housing, which similarly created high-density living in a speedy construction time.

It was one the 20th century's most controversial architecture movements and has since come back in vogue. Recent designs for sweets and wallpaper have all paid tribute to the style.

Four winners will be able to choose three A2 Brutalismo Posters from the selection of the nine cities. Frames are not included. The posters are also available to purchase from This Brutal House, with prices ranging from £30 for A2 size to £45 for A1 size.

Competition closes 27 April 2018. Four winners will be selected at random and notified by email, and their names will be published at the top of this page.
