London Built a Skyscraper That Melts Cars and Knocks People Over — It’s Still Open

On August 29, 2013, Martin Lindsay parked his Jaguar XJ on Eastcheap in London's financial district and walked away for two hours. When he returned, the wing mirror had buckled, body panels had warped and blistered, and the badge was unrecognisable. Street-level temperature readings reached 91°C — then 117°C, hotter than boiling water. A construction company note was tucked under his windscreen: "Your car's buckled, could you give us a call." The source was a beam of concentrated sunlight six times brighter than direct sun, focused by the largest concave mirror ever accidentally built in a European city. This is 20 Fenchurch Street. But the melting Jaguar was only the first problem. Rafael Viñoly designed 20 Fenchurch Street for Land Securities and Canary Wharf Group to compete with modern office towers rising in Canary Wharf. The building rises 160 metres across 37 floors with a south-facing facade that curves inward — a parabolic reflector made of 32,500 square metres of glass. In summer 2013, before louvres were installed, the concave wall focused incident solar radiation into a moving strip of concentrated light capable of igniting combustibles and causing skin burns. A City A.M. reporter fried an egg on the pavement for cameras. Developers paid Lindsay £946 for repairs. By July 2015, the same curved facade was channelling wind downward at ground level with enough force to knock pedestrians off their feet. The City of London Corporation's head of design admitted post-construction wind conditions "differed somewhat" from pre-approval wind assessments. Street vendors were advised to attach warning labels to their carts. Rafael Viñoly later told The Guardian that horizontal louvres had been part of his original design but were removed during value engineering. "A lot of mistakes," he said. He also blamed global warming. This video examines how a single geometric feature — the concave, flared facade — created two entirely unrelated physics failures: optical (solar convergence) and aerodynamic (downdraft). The engineering response came in two phases: temporary street screening in September 2013, then 8,000 individual aluminium brise soleil fins installed by Permasteelisa across 31 floors. The system cost under £10 million. It works. But 32,500 square metres of curved glass curtain wall has no historical precedent — no occupied building in Europe replicates this geometry at scale. There is no data for what this facade looks like at 30 years. The building opened in April 2014. By 2044, the inspection records will tell whether the sealants, silicone, thermal cycling, and asymmetric loading have produced new surprises. 🔔 Subscribe for new investigations every week 👍 Like if this changed how you see iconic buildings BUILT WRONG Engineering Failures.
