I had no idea such a large apartment building existed until a few weeks ago. Fascinating

Housing Debate Unfolds in Shadow of a Living Wall
VERNIER, Switzerland — Alexa Magalhaes has no plans to move from the apartment building where she has lived for the last six years, and why should she? As one of the largest such buildings on earth, it provides for just about all her needs, she says.
“I love this building; it’s a little village, you have everything here — school, medical center, families with children,” said Ms. Magalhaes, a woman in her 30s who shares a bright three-and-a-half-room apartment with her young daughter.
Her sentiments are not universally shared.
“It’s a monster,” said Jean Paul Laurent, 53, whose work for the local public utility occasionally brings him to the area. “I’m from a small village, I live in a three-story house, I call that a human scale,” he said. Yet he admitted that tenants of Ms. Magalhaes’s building, known as Le Lignon, after a river in nearby France, praised their apartments as large and bright, with splendid views and many conveniences.
The debate over Le Lignon is pertinent because the behemoth, with its 2,780 apartments, more than 10 million square feet of floor space and about 6,800 tenants, was thrown up four decades ago largely as a response to an acute housing shortage in the region around Geneva, including towns like Vernier. With immigrants streaming into the area every year, it faces a similar housing shortage today.
If larger cities take pride in the height of their skyscrapers, Vernier, population 34,000, has long boasted about the length of Le Lignon, which at nearly seven-tenths of a mile, was for years thought to be the longest residential building anywhere. There were celebrations to mark the anniversary, and the canton of Geneva, the larger region in which Vernier lies, bestowed landmark status on the huge building.
