A stained glass skylight, designed by Brian Clarke, is installed in the kitchen of Peel Cottage. The window was produced with Ben Day dots, a technique drawn from paper printing. This dotted finish references nineteenth-century Pointillist techniques and the Pop Art prints and paintings that had long-inspired Clarke’s pursuit of contemporary technology and themes in stained glass.

In 2020, Clarke said of the window:

‘It's quite obviously artifice: there's no attempt to make it anything other than a mechanised expression of an idea. And there are sycamore leaves up there, but they're grossly over-scaled leaves, so that when real sycamore leaves fall on them, which they do occasionally, a strange juxtaposition of scale occurs... It transmits a particularly pleasant light from about April to September, and it changes quite dramatically; the Ben Day dots elongate, take on a very liquid quality.’
