Our Bonni palette has been carefully chosen to work in harmony with nature. Our earthy warm tones give a sense of grounding and authenticity, our gentle shades of green offer serenity and calmness, and our more vibrant, playful colours inject some vitality and fun. Enjoy creating, now is the time to make your Bonni your own!

We have carefully selected the very best materials to craft our Bonnis and they are designed to look beautiful, stand up to the elements and age gracefully. Choose from corrugated steel or timber, in vertical or horizontal design, left in its natural form or painted in a colour from our Bonni Palette. Whether your Bonni stands alone in its beauty or harmonises with its surroundings is for you to decide!
