Rules for Better City-Making
UIA 2026 Barcelona
Last updated: August 25, 2026 Barcelona, Spain
From a stage shared by city architects, practice leaders, and cultural institutions, five voices offered five ways forward for making the most of what already exists in the urban fabric.
Treat the existing city as your site
“The city is already there. That's my playground. It's not a blank page,” says María Buhigas San José, Chief Architect, Barcelona City Council. Her team mapped the city and found buildings occupy just a quarter of its fabric — unlocking 100 hectares of overlooked leftover space now becoming pocket gardens and shaded playgrounds.
Make urbanism legible
“It's our role to make architecture more democratic,” says Marion Waller, Director of the Pavillon de l'Arsenal in Paris. Citizens should be taught to better understand the built environment - where materials come from and where their tax money goes in forming a better urban realm.
Think first, build second
“It's a lot cheaper to do good thinking than to build badly,” says Kjetil Trædal Thorsen, Founding Partner of Snøhetta. The Norwegian architect calls for the profession to be practically minded - and think about positive positions worth defending — he borrows his own view from the poet Salena Godden: pessimism is for lightweights.
Learn the language of money
“If you want to change the business, you have to understand it,” says Kika Krista Kjærside, Head of Program at the Danish Architecture Center, whose program brings young architects together with engineers, constructors, and financiers early in their careers — building the shared city-making language that turns good intentions into better built outcomes.
Choose your battles before they choose you
“To be an activist architect, start by choosing the projects you do and the ones you don't do,” says Tatiana Bilbao, Founder and Principal of Tatiana Bilbao Estudio. For the Mexican architect, architecture is a primary form of care — and her meaningful agenda is set the moment a commission is accepted, at every meeting that follows.
A Holcim Foundation Fellow on Rethinking the Architect's Role
The conversation on stage also turned to the next generation: our Executive Director, Laura Viscovich, sat down with Holcim Foundation Fellow Jacob Meyers to make the case for architects returning to city halls.
