A penthouse in Rotterdam by Deen Ontwerpstudio, shaped as a continuous interior where architecture, material and landscape are closely connected. Oak joinery, soft natural finishes and fluid transitions establish a quiet sense of coherence, while expansive glazing extends the living spaces towards the terrace and city beyond. Curved forms and carefully framed sightlines soften the architecture, creating a home defined by openness, restraint and an understated sense of permanence.
