Thirty-five year old Alexandr Ortinsky moved into a 24 square-metre container on the outskirts of Kharkiv, Ukraine's second largest city, earlier this year. "As soon as they started shelling we moved," he says, after fleeing an area held by separatists in Luhansk last summer. His wife and six children, including one disabled son, are with him. Together, they share a space that includes a small kitchen, a bathroom, and toilet. The German built-unit is part of larger modular city for nearly 400 refugees
