David Kohn Architects’ Carrer Avinyo apartment in Barcelona was named Best Interior Design at INSIDE: World Festival of Interiors last month in Singapore. The design remodelled a tight, oddly-shaped period apartment in the city’s gothic quarter to create a stylish and elegant modern pied-a-terre of open plan living room, bathroom and three bedrooms. Playing with natural light and manipulating scale Kohn has created a space that’s a pure delight. Part of that play is on the floors, with his bespoke tiles, made by Mosaics Martí, referencing a triangular public square nearby. The tessellated floor is complex and abstracted, and working with specially designed interior furniture and built-in shelves and storage, creates a total work of architecture.
