Just wanted to express my thanks to @Berthil for the instructions for this. I've spent almost a year getting the parts together, but it's finally complete. What a great model! I made a few changes from the original. Some colour tweaks, like the flowers and the tiled floors. Added a layer of tiles/jumpers so that I could remove the structure to access everything inside, and an iron flower at the front in place of a sign. But it really is fabulous, and I'm very pleased to add it. If anyone wants to try it, you absolutely should - https://rebrickable.com/mocs/MOC-26998/BrickPolis/botanical-garden/
