The Pritzker Prize -- architecture's most prestigious award -- was awarded Tuesday to French duo Jean-Philippe Vassal and Anne Lacaton for their affordable, eco-friendly spaces that prioritize the wellbeing of the many.

Vassal, 67, and Lacaton, 65, received the accolade -- which was first awarded in 1979 and comes with $100,000 in prize money -- for their work transforming urban housing into uplifting and sustainable spaces on modest budgets.
