Roof Lanterns
A Korniche roof lantern turns an ordinary room into the brightest, most inviting space in your home. Sitting proud of a flat roof, its slim sightlines and expansive glass draw daylight deep into kitchens, extensions and dining spaces, making them feel bigger, warmer and more open. It's the kind of change you feel every day, and one that adds real value to your home.
