When I started this series, I had just moved into a basement flat in Edinburgh. After years of living above ground, descending a dungeon-like stairwell to my front door was a new experience for me. But even stranger was the discovery others were living under me. If you have visited Edinburgh, you will no doubt be familiar with the city’s vertical street structure. From the medieval Old Town’s turreted skyline to how many buildings extend far below street level—sometimes up to two or three stories deep.
What is underneath Edinburgh?
In fact, like so many places we’ve explored in this series, Edinburgh has a longstanding history with the underground. During the 17th century, the city suffered from significant overcrowding, forcing residents to live virtually on top of one another. This issue was partly due to the 24-foot-tall Flodden Wall that encircled the city, originally built to defend it against English invasion. With no space to expand outwards, houses packed tighter together. They climbed upwards to 10 or more stories high—creating the world’s first-ever ‘skyscrapers’—while down below, cellars and basements were converted into underground housing.![Edinburgh in the 17th century Wenceslas Hollar](https://spaces.whynow.co.uk/2022/10/edinburghinthe17thcdetailbywenceslashollar1670.jpg)

Underground living around the world
If anything, these accounts confirm the deep-rooted fears of the underground and reflect the social divisions that were—and still are in many places—ingrained in the built environment. Today, in South Korea, for example, lower-class citizens often live in sub-basement homes known as Banjihas. In Beijing, a large population of mainly migrant workers (pejoratively known as “the rat tribe”) lives in cramped conditions in underground accommodation beneath the city. And in the Romanian capital of Bucharest, a generation of children has grown up in the underground sewer. Yet as usable land becomes increasingly scarce in urban centres worldwide, subterranean space has come back into focus. Despite the unappealing aspects of being underground (such as the lack of natural light—quite a big downside considering sunlight’s significance to our health and wellbeing), it also has its benefits. As we’ve seen, underground spaces provide sanctuary from the topside world: practical if there is a war or nuclear catastrophe above; convenient in extreme weather conditions. In Montreal, a 20-mile-long underground complex is an effective pedestrian network during the harsh Canadian winters. Likewise, underground malls in Singapore are used as alternative recreational and social spaces to escape the tropical climate. The underground spaces also have an advantage in energy efficiency as the ground functions as a thermal reservoir for interior temperatures; some have proposed that London’s lost rivers should be used to heat the city and cut emissions. The possibilities of the underground are seemingly endless.Underground millionaire living complexes
Perhaps one of the more controversial phenomenons in recent years, though, has been the growing appetite for private subterranean complexes. We have already explored how nuclear bunkers are on the rise, with the super-rich investing millions into underground real estate reserved for the event of global catastrophe. But in cities like London, underground spaces are becoming not just a temporary retreat to wait out the storm but an extravagant extension of everyday life. Professor Roger Burrows and researchers at Newcastle University have researched the phenomenon of ‘iceberg homes’ in London: deluxe basements that sometimes extend multiple levels beneath the ground. In affluent areas where planning restrictions make it challenging to extend properties laterally or add floors above, the only solution is often to build down. “Our new research now suggests that such developments are emblematic of how London is changing,” Burrows writes for The Conversation. “Along with residential high-rise luxury towers (“luxified skies”) sprouting up across the city, we are also witnessing an epidemic of ‘luxified troglodytism’—super-rich households extending their properties in a subterranean direction by way of basement excavation.” The 2018 study, which aimed to map the “subterranean geographies of plutocratic London”, found 4,650 basements approved for London homes, including 785 large and 112 mega-basements between 2008 and 2017. Typically three storeys or more—or two storeys extending beyond the footprint of the house—these basements collectively boast 367 swimming pools, 358 gyms, 178 cinemas and 63 staff spaces. “We also found 14 car lifts, seven art galleries, two gun stores – and one owner who admitted to building a ‘panic’ room,” notes Burrows. One approved was a three-storey basement in Holland Park with an artificial beach. With fewer laws dictating what can be built underground, virtually anything is possible (so long as you have the budget to match). Such deep-level excavations have inevitably wreaked havoc on nearby neighbours. Besides the noise, air pollution, and general nuisance they cause, deep digging also poses the risk of structural collapse. In 2017, The Telegraph reported that a £1m London home had collapsed “in a pile of rubble” as its owner attempted to construct a vast, two-story basement extension beneath the period property.![Tunnel End Duke of Portland](https://spaces.whynow.co.uk/2022/10/tunnelend-geographorguk-123768.jpg)

Badger from Kenneth Grahame’s Wind in the Willows
Throughout this series, we have descended into the hidden spaces below, from superdeep boreholes to nuclear bunkers to the shadowy nexus of the deep web. In unearthing its treasures and stories, we have seen how the underworld is a repository of our deep past, tracing our shared history to eras long before the dawn of humanity. We have travelled through time and across continents, from the incredible stone cities of Cappadocia in Turkey to modern-day ‘iceberg homes’ of the ultra-rich. We’ve seen how the underground can provide sanctuary in times of turmoil and how it can just as quickly evoke our most primal fears. Paying attention to the underground is vital for—like the Unconscious—it offers a mirror and unique insight into life on the surface. Look closely, and you’ll find an ever-expanding realm beneath your feet: out of sight but never entirely out of mind.
