## Outline
### 0:00 Intro
- **0:02** "This is the moment skyscraper design changed forever." Since the mid-1970s the **Willis Tower**, or **Sears Tower** to locals, has defined Chicago's skyline.
- **0:15** It was the world's tallest building for almost a quarter of a century and influenced engineers worldwide, including the team behind the buildings that eventually took its title.
- **0:29** In **2015** it sold for a record-breaking fee and has since had a half-billion-dollar renovation, but the world has changed fast and the landmark's future is now uncertain.
### 0:48 What's in a Name?
- **0:50** More than 50 years after construction it is still Chicago's tallest building, and people still queue for its observation deck. Yet it may face a big test of what it's really worth today.
- **1:13** Chicagoans still call it the Sears Tower (short clips of locals saying so). Since a British firm renamed it Willis Tower, the presenter sides with Chicago and uses "Sears Tower" as "a peace offering."
### 1:55 The Sears Story
![[images/Does-Anyone-Want-Sears-Willis-Tower-t0140.webp]]
- **2:07** The 1960s were the peak of the American department store, and **Sears, Roebuck & Co.** became America's retail king, arguably the world's largest retailer.
- **2:18** By the late 1960s it had tens of thousands of employees spread across Chicago, including a sprawling west-side campus of offices and warehouses. It wanted a modern, centralised HQ in the **Chicago Loop**.
- **3:04** The building had to fit the workforce and make a statement. Sears estimated about **2 million sq ft** of offices for current staff and optimistically forecast **4 million sq ft** for future growth. That growth never came, but the brief was for a very large, very tall building.
### 3:34 The Location
- **3:35** No site that big existed downtown unless you paid for it. Sears bought **15 buildings** across a **two-block area**, spending more than **$2M** to acquire part of a whole street.
- **4:02** That plot let Sears build the world's tallest building for itself: at **442 metres**, taller than the **World Trade Center** towers topping out in Lower Manhattan in 1970.
- **4:29** The presenter jokes about building a B1M supertall one day, with a giant poster of his face like Elliot Carver's in *Tomorrow Never Dies*.
- **4:55** Sponsor segment: **Rayon Design**, a web-based CAD platform. The presenter lays out a Sears Tower-inspired "B1M Tower" office with a boardroom table, bookcase and chairs, using its **50,000+ block** CAD library, an AI tool that generates custom blocks, and an all-in-one design, edit and present workflow. Free to try.
### 6:12 Bundled Tube Design
- **6:12** Sears held an architectural competition, won by **Skidmore, Owings & Merrill (SOM)** with something revolutionary.
- **6:26** The key question was how to build so tall without enormous cost. SOM structural engineer **Fazlur Khan** answered with the **tube structure**.
- **6:44** Earlier skyscrapers such as the **Empire State** and **Chrysler** buildings used a matrix of steel beams and columns all the way up, plus extra steel for wind bracing. Going to **110 storeys** that way would cost a fortune.
- **7:07** Khan proposed a **bundled tube** design, never done before. Tall, narrowly spaced columns joined by **spandrel beams** make the building act like a vertical tube, which cuts the steel needed to resist wind.
![[images/Does-Anyone-Want-Sears-Willis-Tower-t0460.webp]]
- **7:34** There are **nine tubes** bundled on a **3×3 grid**, each square **75 feet** wide.
- **7:42** The tubes connect on every floor through horizontal beams, and large **trusses at three levels** tie them together more firmly. They show on the outside as dark bands and house the mechanical systems.
- **7:59** No internal support walls are needed, so floors are big, open and flexible, ideal for a corporate office.
- **8:10** As the tower rises, **seven of the tubes step back** at different heights, reducing wind loads and limiting sway.
### 8:20 The Tower's Influence
- **8:20** Built **1970 to 1973**, it gave Chicago the world's-tallest title for the first and only time, and held it for almost **25 years**. Only the Empire State held the crown longer in the skyscraper era.
- **8:50** A year after completion, once all Sears staff had moved in, the tower opened the **Skydeck** on the **103rd floor**, still the highest observation platform in the US. On a clear day you can see about **50 miles** across **four states**.
![[images/Does-Anyone-Want-Sears-Willis-Tower-t0570.webp]]
- **9:16** No major skyscraper copied it exactly, but several borrowed ideas. The **Burj Khalifa**, another SOM project, uses a **buttressed core** to reach **828 metres**: a conceptual evolution of Khan's approach, with three wings around a central core working as one system.
- **9:54** The towers that overtook Sears, Malaysia's **Petronas Towers**, use a **tube-in-tube** system engineered by **Thornton Tomasetti**: an outer tube of concrete columns plus a concrete tube in the core for extra rigidity.
![[images/Does-Anyone-Want-Sears-Willis-Tower-t0595.webp]]
- **10:23** Petronas winning the title was controversial: its **46-metre spires** counted towards its height, but Sears's two broadcast antennas, added in **1982**, didn't. Counting them, Sears would still be taller, and it has a higher occupied floor. The presenter points to The B1M's recent video on **vanity height**.
### 11:08 Changing Times
- **11:08** By the late 1990s, when it lost the title, Sears itself had been moving employees out through the decade and was gone by **1995**. It couldn't afford the overheads and was struggling against **Walmart** and **Target**.
- **11:32** Sears never filled the extra space it forecast. Firms such as **Goldman Sachs** leased upper floors from the start, so contrary to popular belief it was never fully occupied by its namesake.
### 12:19 New Ownership
- **11:52** In **1997** it sold for **$110M**, then changed hands several times over 18 years.
- **12:05** Naming rights went to British insurance broker **Willis Group Holdings** in **2004**, and it officially became the **Willis Tower** in **2009**.
- **12:19** In **2015** investment firm **Blackstone** bought it for **$1.3BN**, a record for an office building outside New York. It looked like a solid buy: a world-famous building in a great city with high occupancy, though "a sum they may now wish they'd haggled down a bit."
- **12:54** The problem: despite being almost full, the building still had a closed-off **1970s corporate feel**. The base felt like a fortress with few amenities, unlike today's sleek, open, mixed-use **Grade A** offices.
![[images/Does-Anyone-Want-Sears-Willis-Tower-t0830.webp]]
- **13:25** From **2017 to 2022** Blackstone spent another **$670M** on a more "human-centric" building: new retail, dining and entertainment, an outdoor garden and terrace, lounges, fitness centres and an upgraded Skydeck.
### 13:56 Imminent Sale?
- **13:57** Blackstone has now sunk almost **$2BN** into the tower, hoping a future buyer will pay more.
- **14:08** Recent reports say it is "exploring options to exit its ownership" and sounding out buyers who might take on its outstanding **$1.3BN loan**.
- **14:24** Breaking even could be hard: the tower was last valued at just over **$1BN**, interest rates are far higher than a decade ago, and a pandemic mid-renovation changed the world of work.
### 14:43 Blackstone's Challenge
- **14:43** An interviewed expert says the building is still popular, with relatively high occupancy and demand to be there, but Chicago faces headwinds: **COVID** decimated office demand, and the city builds so much that the tower competes with plenty of newer offices.
- **15:11** Until Chicago lures companies and people back to offices, Blackstone will have to hold the tower until the market recovers or find a buyer willing to take the risk.
- **15:30** That could be a warning sign for investors in similar deals. Ageing towers need money to keep up, so happy owners matter.
- **15:52** The Skydeck draws about **1.5 million** visitors a year and the building is about **85%** leased, which still might not ease concerns. With few potential buyers in a struggling market, any sale could be very difficult, and more big overhauls look unlikely until they make financial sense.
### 16:24 Conclusion
- **16:24** The hope is that the tower keeps being looked after. The **Chrysler Building** shows what happens when old skyscrapers aren't supported: it is already up for sale at a knockdown price because it is falling apart.
- **16:41** Sears Tower is in a better position and its immediate future looks secure, but that can change.
- **16:52** Sponsor recap (Rayon Design) and subscribe call.
