The building stands unchanged with every passing year. But one day the sight of it is just too dilapidated and depressing, and there are political moves to have the high-rise razed to the ground. By now a ghetto of immigrants where unemployment is rife, demolition of this outmoded tower block seems the obvious solution. But not if the two award-winning French architects Anne Lacaton and Jean-Philippe Vassal have anything to say. “It never pays to demolish social housing in favour of building a new replacement. The costs of renovation will always be lower. Instead, respect should be shown for good and solid buildings that can readily be remodelled and transformed into new and inviting neighbourhoods,” says Anne Lacaton.


Light is vital for plants, animals and human beings alike. But buildings too benefit from abundant daylight. This is true not least in social housing in deprived neighbourhoods, where simple effects and plenty of daylight can give classic concrete tower blocks a whole new lease of life. This discipline is mastered by architects Anne Lacaton and Jean-Philippe Vassal.
