Concept: Brick × Steel Contrast

The historic warmth of brick is paired with the industrial precision of steel framing. To complete the composition, Ninja Deterrent™ spikes were introduced, ensuring this café entrance is not only stylish but also fully protected against intrusion attempts.

Security Meets Design

Above the beam, a continuous line of Ninja Deterrent™ anti-climb spikes provides decisive protection. Their low-profile design allows the spikes to disappear visually into the architecture, while still delivering the proven deterrence that Ninja Deterrent™ is known for in high-end residential and commercial projects.

Adding Warmth with Greenery
