This modular upright bookcase doubles up on both height and width in designers Preben Fabricius and Jørgen Kastholm’s minimalist FK63 series, offering roomy storage or display space to deploy singly or in combination with Carl Hanson & Son’s sister pieces. Handcrafted with a focus on proportion, subtle detailing and natural materials, it’s fashioned in solid FSC-certified solid oak and enhanced by an oiled finish.
