Bay-Window Fog Hills

Bay-Window Fog Hills is an original illustration set in San Francisco Hills, USA. It lies in mid-latitudes, where the climate is warm-summer mediterranean.

Wooden row houses with stacked bay windows stand painted in three-colour trim schemes, stepping down a street so steep the surface draws a visible kink. A bank of fog spills over the ridge behind, and the cool afternoon light is soft.

Why does almost every house have a bay window?

Bay windows push glass out past the facade to catch light on a narrow lot and gather any sun in a city that is often overcast — they are climate as much as fashion. Building in timber on ground this steep says abundant wood and a hurry. Fog pouring over a ridge is cold ocean water offshore meeting warm inland air, a daily summer event on that kind of coast.
