Tropical Garden in an Old Station Shed: An Indoor Botanical Garden

Design a railway station conversion in the manner of Rafael Moneo's Atocha — the nineteenth-century iron and glass train shed emptied of tracks and turned into a covered public hall filled with a full-scale tropical garden, while the actual platforms move to a new building behind. Compose a vast riveted iron and glass vault overhead, hundreds of mature palms and tropical plants growing from a sunken bed on the old track level, travellers sitting on the surrounding terrace, brick end walls retained, bright filtered daylight through the old glazing, wide eye-level view, 24mm lens, interior photography, ultra photorealistic, 8K
