This is a partially completed perspective drawing of Claypotts Castle showing not only the outer form, but also an x-ray style view of the internal spaces. This technique allows an appreciation of how the spaces sit within the seemingly solid form of the castle. In particular, it is helpful to illustrate how features such as window openings, fireplaces and alcoves puncture the solid mass of the external walls. The drawing also demonstrates the splayed nature of the window reveals which are wider on the internal surface of the walls, allowing light to wash along their surfaces and reducing glare in the rooms.
