English Freemason. He probably designed Thornbury Castle, Glos. (1511–22). He built the upper parts of the tower at Lavenham Church, Suffolk (c.1523), and worked at Hampton Court Palace (1533–5). In 1541 he was the King's Master-Mason at Calais and Guisnes, and in the following year was inspector of the fortifications at Hull and Berwick-on-Tweed. If actually responsible for the impressive Tudor military architecture at Berwick, he was the most important designer of such works in the land.
