The use of freeform geometry in architectural design necessitates a progressive building industry to be materialized. Great progress has been made in shaping materials into double curved surfaces by moulds and milling techniques. However, using these techniques in a material and energy efficient way proves to be a great challenge. Current solutions often result in less affordable techniques. In this paper the opportunities and challenges of cold-bent single curved glass are discussed. In comparison to most design industries, the architectural industry often constructs large surfaces with relatively little curvature. By subdividing these double-curved surfaces into single-curved parts, the initial design is translated into a specific material efficient geometry. After translation, the geometry can be materialized in Cold-Bent Glass. In most cases these techniques can compete well with preformed glass solutions.
