- Slick or soft? No thanks. This interior design book is as hard as a rock and as tough as they come. Solid houses with a polished look, but also with a generous dose of poetry and patina. Imagine: brute materials, such as bare bricks, rusty metal, weathered plasterwork, discarded materials and concrete. The imperfect and aesthetic interior designs radiate a warm atmosphere. Also get acquainted with the trendsetters in this book, each of them an artisan with a passion for metal, wood or ceramics. Lifestyle journalist Iris De Feijter and design blogger Irene Schampaert guide you through the book wearing a 'safety helmet'; these are not interior designs or artisans to be dealt with unprotected.
