This wall is from one of the Clare College buildings in Cambridge.
Google maps has an old image of the area. In this case, Bing maps are better. I was just walking around that area when that façade grabbed my attention. I liked the reflection of the clouds in those angled windows. The tree branches on top of the regular spaced planks of wood break a bit the rhythm of them. I decided to go for a black and white processing with this one. I enjoy taking this kind of pictures, with clear geometric patterns.
