Two Dutch designers, collectively known as HUNK-design, have transformed their 19th century top floor apartment into a "unique city paradise." Architect Bart Cardinaal and artist Nadine Roos, who have lived in parts of the house in central Rotterdam since their student years, have created a large outdoor terraced space amid the rooflines of a built up area. By demolishing the existing pitched roof, they have constructed what they describe as their "Cabrio apartment."
