About 20 Fenchurch Street
The name 20 Fenchurch Street is simply the address: Fenchurch Street, in the City of London, which is a historic financial district. The commercial skyscraper is nicknamed The Walkie-Talkie because its shape is thought to resemble a walkie-talkie handset. The 38-story building rises to 160 m (525 ft), and building work wrapped up in spring 2014. Its three-floor sky garden opened in January 2015.
Architect Rafael Viñoly designed the tower, which cost over £200 million. Its top-heavy form is highly distinctive, seeming to expand upward and outward. Above the entrance floor and 34 office floors sits a large viewing deck, and a bar and restaurants occupy floors 35 through 37. Early plans were for a tower of nearly 200 m (656 ft), but concerns about the visual impact on nearby St Paul's Cathedral and the Tower of London led to a smaller design. The revised height won approval in 2006, and a public inquiry in 2007 sided with the developers, after which full planning permission followed.
Piling began in January 2009. The concrete core topped out in March 2012; the structural steelwork followed in December 2012. During construction it was discovered that, with direct sun for up to two hours a day, the building could act as a concave mirror, focusing light onto streets to its south. A permanent awning went up on the south side of the upper floors in 2014.

- A top that flares outward
- The upper floors are wider than the base and curve outward at the crown. Print slowly with good cooling so the flared top comes out clean.
- Fine vertical ribbing
- The facade carries very fine vertical ribs. Print friendly adapts them to the print scale; Full detail keeps them on a larger print, ideally with 0.12–0.16 mm layers.
- One piece with the ground
- 20 Fenchurch Street is joined to the ground in the exported file, and the four-side check found no floating parts, so nothing needs gluing.
- Pick the detail for your nozzle
- In the Buildings settings, set Landmark detail to Print friendly to adapt thin parts and small details to the print scale. Full detail keeps every modeled feature, for larger prints or a finer nozzle.
- Colors
- Buildings, roads, water and ground arrive as separate filament slots in the 3MF. 20 Fenchurch Street takes the building color.
- File format
- You get a 3MF for Bambu Studio, OrcaSlicer or PrusaSlicer. Any of them can save it as STL if you need one.
