Design the exterior of a bohemian Arabic-style hostel. The building features intricate Arabic architectural elements, such as arched doorways, latticework, and mosaic patterns. The façade is adorned with shades of blue and earthy desert colors, with a mix of terracotta and sandstone. Incorporate greenery with potted palms and climbing plants. A cozy outdoor seating area with colorful cushions and lanterns is visible near the entrance, creating a warm, inviting atmosphere. The setting is a desert backdrop with golden sands and a vibrant blue sky
