Imagine we could enter a building and listen to it—hear about the air it breathes, the cold it feels, the cracks no one sees but which are there. Each floor of the building will reveal different organs: the pipes will be the circulatory system; the walls, the skin; the windows, the lungs.

Through a guided route with actors and interactive points, visitors will learn to detect invisible problems—from damp to harmful materials—understand how these factors affect the wellbeing of occupants, how a home without accessibility measures limits the life of an older person… and appreciate the value of building technicians as the professionals who safeguard the health of buildings.

But the experience is not only educational: it is also a tool for dialogue. We will collect feedback data to help us understand what people know and what concerns them: do we know what an ITE (technical inspection) is? Do we feel safe at home? Are we prepared for extreme weather events? In return, each visitor will receive a personalised guide to assess the health of their own home and know when and how to act.

With an innovative format and strong media impact, the project reinforces the public commitment to decent housing, sustainability and quality of life. It is an opportunity to build the city through knowledge and participation.

In 2026, Barcelona will be the World Capital of Architecture. We, the building surveyors, want to use this milestone to place the city—and its challenges—at the centre of the debate. With housing as the main public concern, according to the latest CEO barometer, we aim to identify the challenges that affect daily life and to propose concrete, real solutions.

To this end, we will promote conversations in public space that allow us to listen and engage with citizens, politicians, the economic sector and industry professionals.

The objective is to be an active part of the city’s transformation, because a city that cares for its inhabitants begins by listening to its buildings.
