Sure, let’s break it down step by step. First, map out zones: a central drip‑irrigated beds area for veggies, a shaded companion planting strip for pollinators, and a buffer of hardy native grasses to absorb runoff. Use lightweight, layered planters so the roof load stays low. Install a rainwater catchment and a small solar panel set to power a sub‑floor drip system—this keeps water use efficient and cuts electricity. Add a compost pit on the north side for kitchen scraps; the compost will feed the beds and improve soil health. Finally, schedule crop rotations so each bed gets a rest period, keeping soil nutrients in check and reducing pests. That’s a green, efficient layout that keeps the city cool and productive.

Glad you like the plan. A greenhouse corner will need good ventilation; a small passive design will keep the heat from spilling over into the main beds. For the succulents, place them in the corner with a drip line that runs only when the soil is dry; that saves water and keeps the rest of the garden from getting too moist. Remember to check the roof’s load limit before adding any heavy materials—lightweight pots and a shallow greenhouse are key. With those tweaks, the rooftop will stay green, efficient, and vibrant.

Sounds like a solid plan. Keep the greenhouse small and well-ventilated, and use moisture‑sensing drippers so you don’t waste water. The succulents will add a splash of color without pulling too much moisture. Once you lay out the zones, the whole rooftop will feel balanced and alive. Good luck with the sketch!
