... Some of the world’s most acclaimed architects have given their thoughts on the challenges facing the built environment at a Pritzker Laureates discussion panel at United Nations Headquarters in New York.

The 2016 Pritzker Prize winner, Chile’s Alejandro Aravena, participated in the event – called Pritzker Laureates' Conversation: Challenges Ahead for the Built Environment – yesterday (5 April) alongside Glenn Murcutt, Jean Nouvel, Renzo Piano, Christian de Portzamparc, Richard Rogers and Wang Shu.

In a wide-ranging discussion which touched on challenges such as mass urbanisation, climate change, population growth and bureaucratic planning policies, each speaker underlined the need for positive action among architects, designers, planners, governments and end users to improve the spaces where we live, work and relax.

Among the points raised, Rogers warned that the role of architect has become “that of a decorator” instead of a leader seeking to improve built environments; Nouvel bemoaned the rules and regulations restricting innovative architecture around the world, particularly in his native France; and Murcutt called for more buildings "which look good in real life and not just in photographs.”

CLAD was live tweeting from the event, and a few of the panel’s hard-hitting points and calls for action during the event can be seen below.

Murcutt: The planet having too many people is the biggest problem, but it's an issue which no one wants to talk about #pritzkerprize

Aravena: The migration to cities is good news in principle but scarcity of means to respond has no precedent in human history @PritzkerPrize
