You’ve seen it. Even if you don’t know the address, you’ve definitely seen the silhouette. It’s that top-heavy, bulbous mass looming over the north bank of the Thames, looking a bit like a giant 1990s mobile phone or a very expensive Pringles tube. Most people just call it the Walkie Talkie. Officially, it’s 20 Fenchurch Street London, and honestly, it’s probably the only building in the world that has its own Wikipedia subsection dedicated to melting cars.
Architecture is usually pretty boring stuff for the average person, but this place is different. It’s a lightning rod for opinions. Some people love the futuristic curves; others think it’s an absolute eyesore that ruined the historic London skyline. Rafael Viñoly, the architect behind the project, wanted to maximize the floor space at the top of the building because that’s where the rents are highest. It was a purely commercial decision that birthed one of the most recognizable—and polarizing—shapes in modern construction.
The Day 20 Fenchurch Street London Melted a Jaguar
Let's get the "death ray" out of the way first because it’s the most insane thing that’s ever happened in British real estate. Back in 2013, while the building was still under construction, the sun hit those south-facing concave windows at just the right angle. The building acted like a giant magnifying glass. It focused a beam of light onto Eastcheap, the street below.
It wasn’t just a bright glare. It was a literal heat ray.
Martin Lindsay, a local businessman, parked his Jaguar XJ on the street for an hour. When he came back, the wing mirror and the Jaguar badge had literally melted. A journalist from City AM famously fried an egg in a frying pan using nothing but the reflected light from the building. It sounds like a plot from a James Bond movie, but it was just a massive physics oversight. The developers eventually had to install "sunshades"—basically giant slats—to break up the reflection. If you walk past today, you'll see them. They aren't there for aesthetics; they’re there so the building doesn't accidentally incinerate any more luxury vehicles.

Is the Sky Garden Actually a Garden?
Then there's the Sky Garden. This was the "public benefit" that allowed the developers to get planning permission for such a massive structure. The promise was a "park in the sky," a lush, green oasis open to all Londoners.
The reality? It’s a bit more complicated.
The Sky Garden at 20 Fenchurch Street London is definitely impressive, don’t get me wrong. The views are some of the best in the city, especially looking south toward The Shard and HMS Belfast. But it’s not really a park. It’s a series of tiered terraces inside a glass dome, mostly filled with drought-resistant Mediterranean and South African plants. It feels more like a very fancy airport terminal or a high-end conservatory than a public park.
And then there's the "public" part. Access is free, but you have to book weeks in advance. If you just show up on a Tuesday afternoon hoping to wander in, you're going to be disappointed by the security guards. It’s a heavily managed space. You go through airport-style security, and once you’re up there, you’re surrounded by people paying £15 for a cocktail. It’s a great experience, but the "public park" branding feels like a bit of a stretch by the PR team.

The Wind Tunnel Effect
If you’ve ever walked around the base of the Walkie Talkie on a blustery day, you might have noticed you’re suddenly fighting for your life against a gale. This is the "downdraught" effect. Because the building is so tall and has such a large, flat surface area, it catches the wind and funnels it straight down to the pavement.
In 2015, the wind became such an issue that it was reportedly knocking people over. The City of London Corporation actually had to change their planning rules for future skyscrapers because of this building. They now require more rigorous wind tunnel testing for any new designs. It’s kind of funny—20 Fenchurch Street London has basically become the "what not to do" case study for every urban planner in Europe.
Why It Still Matters (Despite the Car-Melting)
So, why do we care? Why does this building keep popping up in every London travel guide?
- The View is Unbeatable: Because the building is situated slightly apart from the main cluster of "City" skyscrapers (like the Gherkin and the Cheesegrater), you get a much clearer panoramic view.
- Engineering Marvel: Despite the flaws, building something that gets wider as it gets taller is an incredible feat of structural engineering.
- The Price Tag: In 2017, the building was sold for £1.3 billion to Lee Kum Kee, a Hong Kong-based food company (the ones who make the oyster sauce). At the time, it was the highest price ever paid for a single building in the UK.
It’s easy to poke fun at the Walkie Talkie, but it represents the sheer ambition of 21st-century London. It’s bold, it’s weird, and it doesn't care if you like it.

Pro Tips for Visiting
If you're planning to head to 20 Fenchurch Street London, don't just wing it.
First, the Sky Garden tickets drop on Monday mornings (usually) for the following week. They go fast. If you miss out, you can try booking a table at one of the restaurants like Darwin Brasserie or Fenchurch Restaurant. It’s more expensive, but it guarantees you entry without the ticket lottery.
Second, go for sunset. Watching the lights come on across London from that height is one of those "I love this city" moments that makes the security lines worth it.
Third, look at the building from across the river, near London Bridge station. That’s where you really see the scale of it. You’ll notice how it leans over the street, seemingly defying gravity. It’s a bit terrifying and a bit beautiful all at once.
Actionable Insights for Your Visit
- Booking Logic: Set a calendar reminder for Monday at 9:00 AM GMT to snag free Sky Garden tickets. The slots are usually for three weeks in advance.
- Dress Code: If you’re just visiting the garden, casual is fine. If you’re heading to the restaurants (especially Fenchurch), you’ll need to step it up to "smart casual." They will turn you away for flip-flops or gym gear.
- The Hidden View: While everyone looks south at the river, turn around. The view north toward the Tower of London and the rest of the financial district is equally fascinating from the 35th floor.
- Weather Check: Don't go on a foggy day. The Sky Garden is basically a giant glass bowl; if there's heavy cloud cover, you'll be paying for a view of a white wall.
- Security Prep: Treat it like the airport. No liquids over a certain size, no sharp objects. It saves time at the ground floor.
