"Virtually all of the world's fertile land has passed many times through the gut of earthworms"
Worm Towers is a new-build project offering accommodation across three floors to an initial quarter kilogram of worms, situated in the borders of Kitchen Door and within easy reach of local composting facilities. This eco-friendly development is created entirely from reclaimed materials, and boasts a thriving roof-garden.
Worm Towers offers a significant expansion of local organic waste disposal capacity, with the additional benefit of the rapid generation of a nutritious growing medium.

Easy to install ventilation and elevator shafts (poke a hole of appropriate size in walls and between floors).
Shredded newspaper presoaked in rain-water, handful of compost to help residents settle in, damp cardboard covering. Residents are then supplied with food-waste and the occasional portion of ground down eggshells as they dislike acidic conditions. For this reason, onions and citrus fruits are also avoided.
Residents start life on the bottom floor, remaining there until they have filled it with poo. They will then continue their work on further floors. The caretaker of Worm Towers provides regular food and fresh bedding at a rate tailored to residents’ appetites and clears up after them, replacing cleaned floors at a higher level in the building for their continued use. Luckily the worm casts provide a fertile growing medium for use in the surrounding garden.

The stark modernist design of Worm Towers may not to be everyone’s taste, but its impact on the landscape is softened by the fragrant flowering plants that adorn its top floor. While the plants require some watering in hot weather, any excess water is not wasted, as it drips through the building maintaining cool and damp conditions on lower floors.

** I know, I know, I’m supposed to return them for re-use. But I forgot to put them out, and then stopped ordering after a succession of vegetable disappointments.
