Morador de Joinville e conhecido como Ninja Flow, André Luiz constrói um bunker subterrâneo em área rural, mostra nas redes sociais etapas do projeto e diz que a porta de 150 quilos receberá placas de blindagem, enquanto defende que esconder o abrigo e os suprimentos seria essencial em situações extremas.
An underground bunker built in a secluded rural area of Joinville, in the North of Santa Catarina, has become one of the most known projects of influencer André Luiz, known on social media as Ninja Flow. In September 2026, he shared more details about the structure, asserting that for extreme scenarios, his main rule would be to keep others from knowing where the shelter and supplies are located.
According to a report published by ND Mais on September 3, 2026, the content creator has over 1 million followers across platforms and has been sharing the project’s stages for about two years. Among the showcased elements is a door weighing approximately 150 kilograms, which he claims will be armored.

The project was installed far from the urban center, in a designated secluded area. The exact location was not disclosed in the report, in accordance with Ninja Flow’s own idea of limiting exposure of the shelter.

The underground bunker frequently appears in the videos he publishes, which center around preparation for what he considers extreme situations. This structure has been showcased to the public at different stages of development for approximately two years.
Influencer diz que primeira regra é não ser visto
When discussing survival in a potential extreme scenario, André Luiz asserts that the cost or type of material used in the shelter is not the most important aspect.
For him, the priority would be to prevent others from discovering its location. Ninja Flow summarizes this idea by stating that the first rule is “not to be seen,” relating secrecy to both the shelter’s address and the stored supplies.
Material do bunker não seria o ponto principal, segundo Ninja Flow
In the videos, the influencer argues that a shelter could be built using various materials. He mentions wood, bricks, and concrete while explaining his reasoning on preparedness.
His main point is that an underground bunker doesn’t necessarily need to be the most expensive structure to serve its intended purpose. Discretion, in his personal evaluation, is deemed more important than a public display of resilience or investment.
Supplies Should Also Remain Hidden
The idea of maintaining secrecy goes beyond the entrance of the shelter. Ninja Flow also states that food, equipment, and other supplies intended for the site should remain out of third-party knowledge.
According to the logic presented by the influencer, revealing the existence of these resources could compromise the shelter’s utility in a crisis situation. This is a strategy he advocates in his content, rather than a universal technical rule of safety or survival.
Bunker Door Weighs About 150 Kilograms
Another notable element during the construction was the door installed at the entrance. According to the information shared, the structure weighs approximately 150 kilograms.
In one of the videos, Ninja Flow is seen working on the piece, sanding welds and applying a primer to protect it against rust. The door was already installed, but the reinforcement process he presented had not been completed yet.
Armor Plates Still to Be Welded Over the Door
André Luiz stated that he plans to add various plates over the existing metal structure. He compared the planned reinforcement to the armor found on military vehicles.
The claim that the result would be “impenetrable” was made by the influencer himself. The source does not provide technical tests, certifications, or independent evaluations capable of confirming this level of resistance for the underground bunker door.
Project Has Been Showcased on Social Media for About Two Years
The shelter was not just featured in the content published in September 2026. Ninja Flow had been documenting different phases of its construction over approximately two years.
This ongoing coverage has transformed the underground bunker into a recurring series on the influencer’s social media. The videos combine footage of the construction with personal opinions on preparing for scenarios he describes as apocalyptic or extreme.
Over 1 million follow the influencer’s content
The reach of the posts helps explain the project’s impact. According to reports, Ninja Flow has over 1 million followers on the platforms where he shares his videos.
Part of this audience follows content related to the shelter, its modifications, and the strategies presented by the producer. The physical construction also serves as a backdrop for discussions about preparation, isolation, and stockpiling supplies.
Underground bunker costs not disclosed
Although the project involves a heavy door and plans for new protective plates, the report does not specify how much André Luiz has spent on the construction.
Total dimensions, exact depth, occupancy capacity, or internal systems of the underground bunker were also not detailed. Therefore, it is not possible to estimate the investment or technically compare the structure with specialized shelters based on the available information.
Secluded location is part of the strategy
The lack of a public address is not merely a detail omitted from the report. It directly aligns with the principle advocated by the project’s creator.
Ninja Flow asserts that a shelter meant for an extreme situation should remain hidden, regardless of the materials used. The same logic applies to the resources stored within the structure.
Reinforced door attracts attention, but secrecy is paramount
Visually, a 150-kilogram door designed to accommodate armor plates may appear to be the most significant element of the project. However, André Luiz himself offers another interpretation.
For him, the underground bunker would lose its effectiveness if too many people knew its location. Thus, the central factor of his strategy is not just physical resistance, but the attempt to limit knowledge about the existence of the site.
Project Blends Physical Construction and Personal Views on Survival
The shelter in Joinville is a real structure currently under development, while many of the scenarios described by the influencer fall within the realm of hypotheses about extreme crises.
This distinction is important. The door, weight, rural location, and reinforcement design are presented characteristics of the structure; the survival rules reflect the opinions and strategies advocated by Ninja Flow in his videos.
Underground Bunker in Joinville Prioritizes Secrecy Over Investment Size
After approximately two years showcasing the project, Ninja Flow continues to modify the underground bunker installed in the rural area of Joinville. The door, weighing around 150 kilograms, is one of the most striking elements and, according to him, will still receive additional armor plating.
Even so, the influencer claims that his primary concern is different: keeping the shelter and supplies away from third-party attention. For you, in a shelter designed for extreme situations, would it be more important to invest in physical resistance or to keep the location a secret? Share your thoughts in the comments.
