The design duo mencke&vagnby ask questions – of each other, of the design and of the process – and believe that asking questions drives the development that results in a usable, functional and aesthetic product. Their designs emerge from a unique creative process in which the duo ask questions, test ideas and show an understanding of both history and the present day. They design timeless, high-quality products because this extends the product's life cycle – and helps protect the environment and our planet. It is sustainable design with well-considered usability, aesthetics and choice of materials.
