WHEN YOU WANT to hang a picture in your house, you choose one with a size and shape that suits the wall and the room. A rough rule of thumb is that you need to be able to stand at least as far away from a picture as the length of its diagonal: i.e., for a 3.0m x 4.0m picture, you need a room at least 5m deep. Another way of looking at it is that the picture should lie completely within a solid angle (subtended from your eye) of no more than 40°. That's why you don't put big paintings in hallways.
Windows in modern buildings are basically designed to be ignored, regarded as just holes in the wall to be looked through, not at, but that wasn't always the case. There's a lot to be said for dimensioning and placing a window in the same way as you would choose and hang a picture for a particular wall: by paying close attention to the subject (the view), the size, the proportions, and the frame. It makes sense, for example, to leave some wall around the whole perimeter of the window, which preserves the legibility of each as separate elements, and allows the eye to either focus on the window and its view, or see the wall as a coherent whole. If all the windows in the room are designed this way, the eye can flow right around the room without being visually ‘blocked,' and is able to perceive the continuity of the walls bounding the room, which gives a sense of containment and security. This continuous band of wall between openings and the ceiling is called in Japanese ari-kabe, or ‘ant wall,’ supposedly because it would allow an ant to do laps of the room on this unbroken ‘track’.
Somewhat ironically, advances in glassmaking technology have been a major factor in the degradation of windows as design elements. Traditionally, glass panes were created by ‘puddling’ (resulting in a characteristic ‘bullseye’ ripple pattern) or later by hand-blowing glass cylinders, cutting them open and flattening them out, resulting in relatively ‘flawed’ glass and small panes that could only be assembled into large windows by the use of muntins - the slim vertical and horizontal timber members that divide and hold the individual panes. These muntins and the bubbles, ripples and optical distortions of the glass give these windows great charm and make the windows impossible to ignore.
In light of all the above, it is a pity that these days the primary consideration when choosing windows for views seems to be raw size, to say nothing (for now) about the obvious shortcomings in thermal performance guaranteed by the heat pouring in or out of these vast expanses of glass (double glazed, low-e or not). Better that we conceive of windows as subjects worthy of contemplation in themselves, as well as portals to a view- as things to be looked at as much as through.
