Vietnamese practice vo trong nghia architects have completed the 'stone house' with naturally dark blue stones that define an ovular livable wall in a quiet residential area surrounded by the green  landscape. the central oval garden continues through a sequence of spaces onto the inhabitable roof that wraps around over itself in an almost endless natural environment. the interior spaces balance between inner and outer-facing windows representing the introspection of the private life and the connection to the outside world. the rough masonry walls made of 10-cm blocks form the gentle curves, exposing the rugged shadows that play off of the solid-void relationship of the volume. rich dark wood frames punctuating the elevation begin to conjure up the feel of a cavernous medieval fortress made peaceful through the sinuous vegetative canopy. the interior enjoys light-flooded spaces reflecting off of polished timber surfaces with dynamic views over the suburban context and the private central oasis of the house.
