Design the exterior of a tropical residential house with a minimalistic and contemporary box design. Use a neutral base palette of soft whites, warm beiges, and light grays for the façade. Incorporate harmonious accent colors such as fresh greens, ocean blues, and sunlit yellows, with subtle touches of coral or terracotta. Integrate natural elements like bamboo, rattan, and wood for detailing, and include lush greenery and tropical plants to enhance the tropical ambiance while maintaining a clean, modern appearance."
