Combine industrial materials like brick and metal to create a unique urban garden gateway. Use bricks to build sturdy pillars and attach metal gates or panels between them. The combination of brick and metal adds a touch of elegance and sophistication to your outdoor space. The contrast between the warm tones of the bricks and the cool tones of the metal creates a visually appealing look. Plant low-maintenance shrubs or install decorative lighting along the pathway to enhance the overall ambiance.
