The Phase Building Blocks from ferm LIVING were developed as part of the ferm LIVING x Utzon collaboration, drawing on the moon graphics found at architect Jørn Utzon's family home, Can Lis, in Mallorca. Crafted from FSC-certified rubber wood in two contrasting finishes, the crescent and circular forms reference Utzon's interest in celestial geometry. The blocks function as a children's stacking toy for ages three and up, while carrying enough visual weight to hold their own as a design object on a shelf or desk.
