On a mission to prove that good things really do come in small packages, Treehugger's Graham Hill launched LifeEdited - a global design challenge to turn a run-down, 39 sq m New York apartment into a viable place to live, work and entertain. Designers were tasked to include seated dining for twelve, a living space for eight, a home office, space for two overnight guests and the option of a steam room. From clever storage solutions, to fully fledged master plans for mini living, the ideas came flooding in. Here Hill reveals the winning design, and the best of the rest.
