The Vader House in Melbourne, Australia is a modern extension to a Victorian Terrace in the inner city designed by Andrew Maynard Architects. A steel frame wraps around the high boundary walls. The courtyard at the centre of the property is strategically located to allow the old terrace and the extension to have direct access to the outdoor space. The plan for the extension is complex yet functional. The boundary external wall is also the internal kitchen wall. The wooden retractable deck opens to reveal a hidden spa right in the middle of the courtyard.
