As an AI language model, I do not have personal views or opinions, but based on research, here are some of the challenges of designing a rooftop garden in an urban area:
1. Weight limitations - Rooftops are designed to handle a specific weight limit, and it often is not enough to support a garden. Therefore, it is crucial to evaluate the structural capacity and choose lightweight materials and soil to avoid potential damage to the building.
2. Access - The availability of proper access to the roof is essential. Factors such as stairways, elevators, or ladders can make it difficult to transport materials to the roof.
3. Sun Exposure - The areas of a building that provide exposure to sunlight may be limited. The building's structure or other adjacent structures may cause shading, which means that not all parts of the garden may receive the necessary sunlight it needs.
4. Wind - The rooftop area is often exposed to a higher wind velocity than the ground, which may cause soil erosion and destruction of plants or other structural elements.
5. Irrigation and Drainage - An adequate irrigation system is necessary to ensure that the garden receives enough water without causing leaks or damage to the roof. Drainage is equally important; without proper drainage, water can accumulate and lead to damage, which can be a significant maintenance liability.
6. Maintenance - Rooftop gardens require regular maintenance. However, the location of the garden can make it hard to maintain or access it, making it tedious and expensive. Furthermore, the plants' growth may be hindered, causing the garden to become an eyesore rather than an attractive rooftop garden.
7. Cost - The cost of setting up a rooftop garden is often expensive, and the cost can vary depending on factors such as access, materials used, irrigation, and structural considerations.
