Backyard UNDERGROUND Apocalyptic BUNKER
Colin Furze just turned an ordinary garden shed into the trapdoor entrance for a fully kitted-out survival bunker buried in his own backyard.
In November 2015, the British inventor and YouTube builder capped off a months-long project in Stamford, Lincolnshire, with the final reveal of his underground apocalyptic bunker. The build, chronicled across a multi-part series on his channel, ends with ‘Backyard UNDERGROUND Apocalyptic BUNKER’ — the video where Furze walks through the finished structure, hatch and all.
- The steel-and-concrete shelter sits roughly 10 feet underground and measures about 16 feet by 20 feet.
- Access runs through a trapdoor hidden inside a normal-looking garden shed, down a metal ladder and vertical shaft.
- The interior mixes survival basics — canned food storage, a working toilet, lighting and ventilation — with man-cave extras like a flat-screen TV, video game consoles and a drum kit.
The Dig and the Build
Furze didn’t start with a shed and a shovel. He brought in heavy machinery to excavate the yard before lowering a custom welded-steel frame into the pit. From there the crew poured substantial amounts of concrete to reinforce the shell, then backfilled soil over the roof so the finished structure disappears beneath the lawn and garden beds above it — the kind of concealment work that echoes what backyard builders attempt on a smaller scale with projects like a poured concrete curb for a fence.
The scale of it — a room the size of a one-car garage, sitting a full 10 feet down — put this well beyond a hobby dig. It’s closer in spirit to the buried, climate-shielded living spaces seen in places that build underground by necessity, the way homeowners do in Australia’s underground homes, except Furze’s motivation was doomsday prepping wrapped in a joke.
The Trapdoor Shed
The genius of the design is the disguise. From the outside, it’s just a garden shed. Step inside and lift the trapdoor hatch, though, and a metal ladder drops down the vertical shaft into the bunker proper — no bunker-shaped mound, no obvious steel door, nothing to give it away to a passerby. It’s the same kind of repurposed-outbuilding thinking that’s turned ordinary sheds into unexpectedly serious builds elsewhere.
Subsurface Exploration Findings
Once inside, the space reads less like a fallout shelter and more like a subterranean den. There’s a kitchen counter and a microwave, shelving for canned food, a working toilet, fold-out bedding, and functional lighting and ventilation to keep the sealed room livable. Then there’s the stuff that has nothing to do with survival: the flat-screen TV wired to game consoles, and a full drum kit set up in the corner.
Furze built the ultimate man cave and survival cell rolled into one sub garden room — and said it’s finished, and it’s amazing.
That blend is the whole point of the project. It’s not a minimalist Cold War-style shelter built purely for rationed survival; it’s a space meant to be lived in and enjoyed even on a day when nothing is going wrong outside.
Persistent Data Gaps
Furze was upfront that the bunker wasn’t a finished survival system just because the living quarters worked. At completion, he noted that specialized air filtration and a secondary backup power source were still potential future additions — the room was functional for shelter and downtime, but not yet hardened against the kind of prolonged, no-outside-contact scenario a true apocalypse bunker is supposed to handle.
The build also had a commercial angle: it was sponsored in part as a tie-in with Sky 1’s apocalyptic comedy-drama ‘You, Me and the Apocalypse’, which lines up neatly with the tone of the finished space — serious engineering underneath a joke about the end of the world.
Furze has never been shy about turning half-finished projects into new videos once he adds the next piece, so anyone waiting on the air filtration and backup power upgrade has good reason to expect a follow-up dig in that same Stamford backyard.
