Deep in the bamboo forests of Sichuan, China, a man known as Mr. Who pressed a water core drill against solid sandstone and began hollowing out the only home he had ever truly wanted to build. What followed was not a weekend project or a viral stunt but seven years of grinding physical sacrifice, structural improvisation, and stubborn refusal to quit. For millions of people who have ever dreamed of building something entirely their own, his story arrives as proof that the gap between impossible and finished is just time and stubbornness.
The plan took shape in 2019. Who had spent years in coal mining and construction, learning exactly how rock behaves under pressure and exactly where it fails. That knowledge gave him a blueprint: carve a ground-floor master suite into the cliff face, excavate a second floor above it for his two children, and connect both levels with an internal staircase that would have to align perfectly from opposite ends of the dig.
When the mountain refused to cooperate
Sichuan’s rain made itself known almost immediately. Water found every crack, overwhelmed the drainage trench Who had cut along the floor, and blew straight through the cement he had applied as a seal. His fix was characteristically precise: reinforced cement layered with expanding foam, but intentionally left with small ventilation gaps so the rock could breathe and humidity would not build up behind the wall. Mesh screens went over the openings to keep insects out.
The structural challenges ran deeper than water. To clear the main room without bringing the ceiling down, Who carved a massive central pillar and left it standing while he shaped the surrounding walls into an arch, transferring the load into the stone on either side. Only then was it safe to remove the pillar. Moving the resulting half-ton of rock required a different kind of ingenuity: he rolled it out on the cylindrical stone cores his water drill had already extracted from the walls, reusing every scrap the mountain gave him.
When his drill bits wore down to useless stubs after weeks of continuous sandstone work, he built a makeshift forge with a hairdryer forcing air into the flames and restored all 36 bits himself rather than waiting for replacements to arrive from the outside world.
The staircase that had to land blind
The internal staircase was the moment the entire project either proved itself or collapsed. Who had started the lower section more than a year earlier, then paused and excavated the upper floor, planning to carve the connection top-down into a space he could not see. His calculations had to be exact. As he put it, there was ‘zero room for error.’ When the two sections finally met, the alignment was flawless. Three years of independent engineering converged in a single breakthrough that unified the home.
Then life intervened. Just as the house was approaching completion, an unexpected personal matter pulled Who away for nearly two years. When he returned, Sichuan’s humidity had taken over. Vines had consumed the facade, the wooden bed had rotted completely, and mold covered the interior. Rather than despair, he framed it as a durability test: nature had revealed every weak point, and he would now rebuild each one stronger.
A stone desk still waiting for the children
On the second floor, carved directly into the sandstone, sits a honeycomb window Who designed so that every drill hole angles slightly downward, channeling rainwater out of the room during storms. Beside it, a stone desktop hollowed from the cliff face holds the shape of the studio space he is still expanding for his kids.
Seven years after the first cut, Mr. Who can cook meals in a bamboo-roofed outdoor kitchen, sleep under an arched sandstone ceiling, and step from the lower master suite up seven internal stone steps to the children’s floor above. His family visits when they can, spending time in the place he built for them, waiting for the day they move in for good.
