Xamfrà

Cities generate data every day. The problem is that, for whoever has to decide, it is scattered across portals, GIS, intranets and case-management systems from different bodies, each with its own format and date.

We wanted to see what happened if all of it lived in one place, could be asked in plain language and every number said where it came from. No client commissioned it: we built it because we wanted that tool and it did not exist the way we imagined it.

One question at a time. “Who lives far from a health centre?”, “where does the bus run most often?”, “which roofs could produce the most solar energy?”. Each of the 87 views answers a single question, with its legend, its source and its year. You can go from the whole AMB to a municipality, a district, a census section and a building without changing the question.

Read, measure, test. Reading means choosing a view and brushing the legend to light up the sections that fall within it. Measuring means hovering over a building, a street or a stop and getting its card: address, walking distance, nearby facilities. Testing means 23 tools — a new facility, a superblock, a new volume — that compare before and after and export to PDF, CSV or JSON.

Figures are never made up. 98 official sources with publisher, period, licence and load date; 2,077 files with their SHA-256 fingerprint. No number is generated by AI, missing data is never painted as zero and a scenario is always labelled as one. The assistant (beta) opens the view and cites the source of every figure.

And a brand that comes from the Eixample. The name comes from Cerdà’s chamfered corner — the xamfrà — and it is the system’s only ornament: two-chamfer panels, octagons, yellow only for what is selected. We also made the landing page, a series of studies with our own method and the promo film in horizontal and vertical.
