Patrick Schumacher, who worked on the London Aquatic Centre for the London 2012 Olympics, claims centrally-located, "hotel room-sized" studio flats are all young people need.
In a briefing paper, he wrote: "Those who are now making the hard choice between paying 80 per cent of their income on a central flat versus commuting from afar, will in the liberalized future appreciate new options and perhaps choose to pay only 60 per cent for a smaller but more central flat.
"For many young professionals who are out and about networking 24/7, a small, clean, private hotel room-sized central patch serves their needs perfectly well."
How can an architect say that Millennials dont need a living room ??

Mr Schumacher also says the Adam Smith Institute's recommendation of 38 squared metres for newbuild apartments is "paternalistic" and preventing poor young people from getting on the housing ladder.
Millennials responded in droves online, with many outraged at his apparent ignorance of the young people who are not "out and about networking 24/7".
I hate this ridiculous idea that millennials are all somehow perpetually 22 with no responsibilities. I'm 31 and a dad of two, of course I need a bloody living room

"Not the people who are paid much less to cook the breakfasts, serve drinks, clean venues, etc?"
👇 is unreal. Why does anyone even have to contribute to this article? Bonkers. The amount of people I know who live in crappy property in London and the sheer amount of adverts on SpareRoom with ‘no living room’ (there’s even a filter!) is criminal. ‘Millennials’ are human too.

Meanwhile Hannah Shaw-Williams suggest Mr Schumacher's thinking could lead society down a slippery slope.
2018: "Millennials don't need living rooms."
2019: "Millennials don't need kitchens."
2020: "Millennials don't need bathrooms."
2021: "Come on, Millennials, do you really need a whole room just for your bed?"
2023: "Generations Z don't need coffin linings."

Meanwhile journalist Alan White suggested: "This is true, they actually just need a single giant hollowed out avocado."
The Standard approached Mr Schumacher for comment.
