New offices for Blackwell publishers at Oxford are a clever refurbishment of an existing warehouse (architect Berman Guedes Stretton). By using Kalwall, the working areas are flooded with natural and evenly diffused light. Unlike glass, Kalwall gives glare-free transmission without shadows or hotspots. Roof systems can span up to 35m with secondary structure, be walked on and are virtually maintenance free. Vaults, pyramids, geodomes and flat roofs are all possible.
