Torre Bolueta

The Torre Bolueta is an 88-meter-tall (289-foot) skyscraper in Bilbao's Bolueta district, which gave the tower its name. Construction began in 2015 and was completed in 2018. Part of the Bolueta Homes urban complex, the 28-story building contains 171 subsidized housing units. It is considered the tallest Passivhaus in the world, a title it secured in 2018. The architecture was designed by the firm Varquitectos. Despite its innovative energy efficiency, residents faced challenges after the building was completed, complaining of excessive heat in their apartments and demanding solutions from the responsible housing company.
