Note 352 — CHAPTER 15 THE DEVELOPMENT OF THE DETACHED HOUSE IN ENGLAND AND AMERICA FROM 1800 TO 1900

At Perrycroft the mullions are of wood, originally painted green. At the Forster house they were of stone, and that is true of almost all the later houses. So also the slates here were Welsh and grey; when he began to work in the Lake District he turned to green slates, earlier used by Godwin on Whistler’s house. These became standard on his later houses wherever they were built.
