House 323: A Stepped Urban House Opening to Garden Light
House 323 commands a steep street in Sofia, Bulgaria, where I/O Architects set a dark, introverted volume against the city’s edge. Behind the brick mask, the house opens toward its garden and the nearby mountain, unfolding as a calm, glass-lined dwelling for a single family. Interior rooms follow that shift from compression to release, moving from a sheltered entrance to broad views and generous terraces.
