The pieces take form from laminated inch-thick sections, stacked and then sculpted into biomorphic shapes. An ode to his designs from the Sixties and Seventies derived from wood - the lamination process creates a banding effect, revealing a pattern of striation. The formation of these works begins with the selection of the finest timber available, which is carefully glued together and clamped until they harden into a unified whole. The piece is then sculpted, carved and finely sanded in a labourintensive, highly specialized process. More flexible then conventional methods of woodworking, this innovative process allows Castle to make furniture of virtually any size and shape, achieving a striking range of sculptural forms.
While he begins with a specific form in mind, Castle "reads" the wood's natural gain and approaches each of his piece as a process of discovery. “You begin to have a conversation,” he says. “Unexpected things might happen as I’m digging into the wood.”
