BIM Architecture: Xiaoxi Homestay Featuring a Chaotic Staircase and Large-Scale Building Materials

Game Homestay

At the end of 2020, near the Great Wall at Shuiguan in Huairou, Beijing, we designed three courtyards for Xiaoxi Homestay—perhaps better described as a rural inn.

I have designed and operated similar hotels before and cherish the idea of experiencing a lifestyle “detached from daily life”—living fully in the “here and now.” The house in this project is not primarily a “home” filled with its owner’s memories, but serves more as a “theme park,” a game that blurs the line between reality and fantasy.

Since this is a game, it needs rules. The owners requested simplicity and wished to preserve the existing structure, maintaining three courtyards and three distinct façades. Beyond that, the specific gameplay was left to our creativity.

Dangerous Great Wall

The site is unique, with the Ming Great Wall within easy reach. Its imposing features are an undeniable attraction, yet they also evoke a sense of awe and distance.

My approach is to find the emotional connection between people and the place. Why is the Great Wall so moving? Because of its superhuman presence. Unlike the Egyptian pyramids or Nazca lines, which reflect dialogues with gods, the Great Wall emerges from a different origin: “danger.” Built along the most perilous ridges to fend off threats, it alters the energy and courage of the landscape. Though familiar since childhood, seeing it in person still inspires a sense of awe that is both unexpected and justified.

Inspired by this, I became interested in incorporating elements of “danger” into otherwise safety-focused architecture. Would this provoke new kinds of stimulation and strength? I’m not sure, but I’m curious.

Thus, the game was set around three scenes themed on “danger.”

The Third Play: ‘Chaos is a Ladder’

At the Foot of the Great Wall

The final chapter of the game leads us to the Second Gate Castle, once a crucial entry point to the capital. Huanghua City, known as the “Golden Soup,” was the first pass, with the second pass serving as its outer defense. Now, the city wall lies in ruins, bricks scattered across houses. Only two stone city gates remain, hidden beneath overgrowth, silently revealing their history.

In recent years, families have built new homes—no castles remain—and the Great Wall itself has gradually faded compared to old photographs. In 2013, to promote tourism, villagers collected old bricks to restore a former enemy building on the original city platform, which now serves as the façade of Erdaoguan. Our project site is adjacent to this.

With the sudden emergence of dozens of homestays, the village has rapidly evolved—with buildings growing “faster, taller, and more numerous.” For example, while we debated shrinking eaves by a centimeter, our neighbors suddenly built a white house with two red birds perched atop.

The locals embrace these changes, and perhaps the Great Wall itself has grown indifferent, having witnessed 600 years of transformation. It continues to embody its original purpose, quietly demonstrating the immense energy forged from danger and the unwavering will to overcome mountains and rivers.

Antenna Dance

Standing on the base, as close as the Great Wall, another element demands attention: the antenna. Its rapid growth and imposing presence often cause us to avoid looking at it.

Yet, when placed alongside the Great Wall, I noticed a shared formal beauty: both exhibit tension through the courage to rise above the ground beneath them.

They also embody contrast. The Great Wall was built along the most challenging ridges to block invaders, while the antenna rises from the easiest roadside to connect people.

However, connection and blockage are two sides of the same coin. The Great Wall appears to connect by blocking, while antennas bring the internet that connects the world, yet also trap us in virtual cocoons, severing real connections. Watching the hurried delivery workers on the streets, this feels like the danger of our era.

Imitation Connection

The booming homestay market reflects a tension between “authentic experience” and “internet celebrity check-ins.” As a checkpoint on the Great Wall, we are inevitably part of this dynamic. Instead of resisting it, we chose to embrace it.

We mimicked the willful act of “forcibly connecting” the Great Wall and the antenna by creating a third structure on site—an object seemingly “connected but actually disconnected.”

It is a pedestrian bridge that rises and falls over the original building, spanning left and right—sometimes attached, sometimes suspended.

Tianqiao Great Wall Antenna

Following the game’s rules, we preserved the original house as much as possible, removing only the blocked ceiling in the middle of the courtyard. This excavation allowed the long courtyard to gradually descend from west to east. The street-facing restaurant sinks partially below street level, offering a more direct view of the Great Wall from the courtyard.

At the same time, this design enhances visual connections between the interior and exterior. The old wooden frame of the original house remains, with the southern roof raised to introduce sunlight and tree shadows, creating a cozy small bedroom.

Above the courtyard is a 30-meter skybridge that overlooks the winding Great Wall on one side and connects to the massive ruins of the city gate on the other. Walking down the bridge, gently touching the stone foundation of the Great Wall, the distant enemy tower emerges once again. It seems within reach, yet the Great Wall beyond the triangular gap is severed by a village road—perhaps created when villagers broke through the old wall.

The pedestrian bridge itself breaks at this point, leaving a walkable gap covered in weeds. This gap unintentionally transforms the skybridge and Great Wall into a connected landscape, popular among internet celebrities’ photos.

This illusion of connection contrasts with the reality of disconnection. The ancient Xiongguan Pass has been replaced by a semi-transparent triangular wooden structure. The remaining walls along the road border an empty field. Under the watchful eyes of falcons, villagers’ simple daily lives provide an ideal backdrop for photoshoots.

The large windows of the sunken restaurant reveal the architect’s intention to connect the public interior and exterior spaces. Yet, in reality, this only creates a transparent barrier between tourists and residents, whose lives remain incompatible. Meanwhile, an elderly woman sunning herself daily on a stone bench adds genuine warmth to the scene.

Compared to the silent Great Wall, the antenna is more conspicuous. It occupies the vacant land left by the city gate with a tall pole, serving as a landmark and signal tower. The Great Wall and surrounding houses are intertwined within it.

Facing this overwhelming presence, Tianqiao remains calm. Instead of evading or avoiding, it embraces the antenna, dancing horizontally in parallel or direct confrontation—using “poison to fight poison.”

This is no longer a physical connection but a bridge of communication between tourists and residents, reflecting mutual care between virtual lifestyles and real daily life. Just as the chaotic antenna scene is magnified and highlighted in a young girl’s check-in photo, the question remains: is ignoring or erasing it a multiple-choice or an advanced Photoshop challenge?

Can I Ask, Where Is the Way?

Facing the past, let alone the future, can the seemingly infinite connectivity of the present era bear the cost of severing reality? Perhaps the answer lies on platforms like TikTok and Xiaohongshu.
