Grimm's Building Boards - Rainbow

The Grimm’s Rainbow Building Boards transform playtime into a vibrant architectural adventure. With 11 solid lime wood pieces in bright rainbow colours and varying sizes, children can explore stacking, arranging, and designing in bold, colourful patterns. The set can be used independently as a creative floor puzzle or combined with other Grimm’s 4×4 scale sets, including the 12-piece rainbow set, to build imaginative dollhouses, towers, bridges, and more.

The vivid colours encourage pattern recognition, sequencing, and visual learning, while the tactile wooden pieces support fine motor skills and spatial reasoning. Children can experiment with balance, structure, and symmetry as they create both simple and complex designs.

Handmade in Germany from durable lime wood and finished with non-toxic, lead-free water-based stains, the Rainbow Building Boards are eco-friendly and built to last. Perfect for solo or collaborative play, the set sparks creativity, imagination, and open-ended learning. Combining playful colour with timeless wooden craftsmanship, these boards provide endless possibilities for exploration, design, and architectural fun for children of all ages.

About Grimm's

Grimm's toys are inspired by the principles of Waldorf Steiner and are designed with the intention of helping children discover and develop their own creativity through simplicity of shapes, leaving plenty of room for independent play and imagination. Inspired by the educational philosophies of Rudolf Steiner, Grimm's puzzles, building sets, and toys are about the rainbow, happy colors, creativity, and the imagination. There are no instructions, and you can do no wrong with a Grimm's toy. Just play, learn, and enjoy.

Please note: as Grimm's uses non-lacquered wood, some paint transfer can occur during play. This is considered normal. Non-lacquered wood has a lovely texture - the rough texture of the stained wood is not only an important tactile sensory experience for children, but those rough surfaces makes it possible to build in many different ways, because the parts do not slide down so easily as the wood surface is still natural and not covered with a layer of bright enamel; however if you are concerned about paint transfer we suggest you purchase another item that is lacquered to be on the safe side.
