A statistic that appears in a report stays in a report. A statistic that has been built at full scale, placed in a public space, and physically entered by the people it describes does something different. Riksbyggen, one of Sweden’s largest housing developers, and BBDO Nordics understood that distinction and built three micro homes to prove it.
The Data That Became Three Buildings
Riksbyggen developed the Square Metre Index, a new analytical tool that calculates how much property an average 25-year-old in Sweden can realistically afford to purchase, using actual income data, realistic savings rates, current mortgage conditions, and local house prices across 209 Swedish municipalities.
The results confirmed what young Swedes already knew but had never seen quantified with this precision. In Umeå, a university city in northern Sweden, an average 25-year-old can afford 4.5 square metres of property. In Gothenburg, Sweden’s second city, the figure falls to 3.1 square metres. In Stockholm, the capital and Sweden’s most expensive housing market, the number is 1.9 square metres.
For reference, the average single bedroom in the UK measures between 7 and 9 square metres. A young person in Stockholm can afford to buy just over a fifth of a standard bedroom, and cannot afford the bedroom itself. Across all 209 municipalities covered by the index, 111 of them fall below 10 square metres.
The Installations
Rather than publishing those figures in a report or placing them on a poster, BBDO Nordics and Riksbyggen commissioned the construction of three full-scale homes, each one built precisely to the square metreage an average 25-year-old can afford in that specific city. Each installation was designed in a different architectural style, referencing three distinct eras of Swedish residential architecture: turn-of-the-century, functionalist, and contemporary. The result is three physically accurate homes, each one a different period piece, each one smaller than the average bathroom in any of the apartments that Riksbyggen builds.
The campaign name in Swedish is Visning av verkligheten, which translates as Visualisation of Reality, a phrase borrowed from the Swedish real estate tradition of the property viewing, where potential buyers walk through a home for the first time. The installations invited passers-by to do exactly that, to step inside and experience the reality of youth housing affordability in Sweden not as an abstraction but as a space they were physically occupying.
Isabel Lechte, Strategic Marketing Communications Manager at Riksbyggen, described the campaign’s ambition directly: “We wanted people to experience the housing crisis rather than just read about it.”
Anton Bolin, Art Director at BBDO Nordics, described what the installations achieved that no report could: “Standing in front of a 1.9-square-metre house requires no explanation.”
The Response
The installations generated more than 10 million views on TikTok and 75 pieces of media coverage across Sweden and internationally. Sweden’s Minister for Housing visited one of the installations, converting a public experiential campaign into a moment of political engagement that a conventional advertising campaign could not easily have produced. The housing crisis it visualises is already a subject of national political debate in Sweden. The Square Metre Index and its physical manifestations gave that debate a new and more precise emotional anchor.
Why the Format Works
Sweden’s housing affordability problem is not secret information. Young Swedes know that housing in Stockholm is expensive. What the Square Metre Index provided was a specific, verified, and visualisable number. What the installations provided was a way to feel that number rather than know it.
A person who steps inside a 1.9-square-metre structure and understands that this is what an average 25-year-old in Stockholm can afford to buy has experienced something that percentage figures and price indices cannot communicate. The body understands scale in a way that the mind processes differently from data. Riksbyggen and BBDO Nordics built three buildings specifically so that understanding could happen in a body rather than on a page.
