"Ultimately we just want to make a difference, make a positive impact for our wildlife." Green&Blue was founded in 2005 by husband and wife team Gavin and Kate Christman, who met whilst working at Dyson. Relocating to Cornwall, the couple launched with the Birdball birdhouse, a spherical, ceramic birdhouse inspired by the true form of nature. The Birdball birdhouse went on to win design awards from Wayne Hemingway and to be stocked by prestigious names like the Conran shop. In 2014, after several years of prototyping and testing, Green&Blue launched the Bee Brick, a concrete nesting site for solitary bees, designed to be used in place of a standard brick or block in construction, as well as freestanding in the garden. Again, Bee Brick was inspired by the way in which historically solitary bees nest in old crumbling walls, which are fast disappearing as we build ever more 'perfect' properties. Bee Brick won the Soil Association Innovation award that same year. Green&Blue are on a mission to make homes havens for wildlife and have a vision of reconnecting people with nature, supported by the products they manufacture and the awareness they spread of our wildlife and the natural world.
