Recycling discarded materials into new buildings and adapting disused structures to new uses is not just about sustainability – it is also about savvy innovation and stylish adaptation. Some architects build modular wonders from existing units (such as shipping containers). Others draw from recycled, found and local materials (or entire old buildings) to create aesthetically amazing designs that brilliantly blend old and new.

Spiral island (shown above) is just one such example: an incredible mobile private island floating on 250,000 recycled plastic bottles off the coast of Mexico. From a pre-industrial pigsty converted to a postmodern home and a magnificent monastery built from a million glass bottles to adaptively reused cargo containers, airplane hangars and water towers, here are twenty awesome more examples of brilliantly creative and sustainably innovative recycled architecture.
