From the 15th century, under the House of Tudor, the prevailing Gothic style is commonly known as Tudor architecture, being ultimately succeeded by Elizabethan architecture and Renaissance architecture under Elizabeth I (). Rickman excluded from his scheme most new buildings after Henry VIII's reign, calling the style of "additions and rebuilding" in the later 16th and earlier 17th centuries "often much debased". Architect and art historian Edmund Sharpe published in 1851 "The Seven Periods of English Architecture", in which he identified a pre-Gothic "Transitional Period" (1145–90) after the "Norman" period, in which pointed arches and round arches were employed together. Focusing on the windows, Sharpe dubbed Rickman's first Gothic style the "Lancet Period" (1190–1245); divided the second into first the "Geometrical" (1245–1315) and then the "Curvilinear" (1315–1360); and named the third style "Rectilinear" (1360–1550).
