I'm designing a garden bed for a pottery studio in a bird sanctuary. It's going to be a native plant pollinator garden based on year-round food supply for birds, but I wanted to take it up a notch and do something unique to incorporate pottery with horticulture. Garden pots were too obvious and the space is too moist for slow-release watering pots. Instead I'm going to try to work with the potters to make a dovecote: https://en.wikipedia.org/wiki/Dovecote

Dovecotes are an awesome historical Eurasian/African permaculture technique. By providing a safe tower filled with nesting boxes, farmers could passively collect guano and meat throughout the year. We obviously wouldn't be eating the birds that roost there, but the guano would be used in surrounding beds and it would help to educate the public on alternative ways to use/fertilise their yards. I'd like to do a scaled down version of the Egyptian pigeon towers, maybe with some art nouveau detailing:
