In addition to managing the flow of people in the spaces of the museum in order to maximize freedom of movement and choice, Irwin also modified the industrial window grids to create perceptual ambiguity, placing transparent glass in the inner four panes while using frosted glass for the outer panes. With this, Irwin solved the problem of either having the windows become a wall of glaring light, if all transparent glass was used, or having them become a claustrophobic muffling of space, if all frosted glass was used. Irwin's windows catch the eye in a back and forth oscillation between distant and proximal focus.
It is unusual to find such mismatched elements on a single facade as this fine stonework coexisting with these stained and rotting shutters, on a house in the fortified town of Feltre, in the northern Italian province of Belluno.
Where considerable labour lies behind the cutting and fitting of the stone, the timber planks have been left in their raw state, with no paint or carved decoration. Even the iron hinges are of the plainest variety.
Take the use of enormous plate windows...they deprive our buildings of intimacy, the effect of shadow and atmosphere. Architects all over the world have been mistaken in the proportions which they have assigned to large plate windows or spaces opening to the outside. We have lost our sense of intimate life, and have become forced to live public lives, essentially away from home.
In Broussa in Asia Minor, at the Green Mosque, you enter by a little doorway of normal human height; a quite small vestibule produces in you the necessary change of scale so that you may appreciate, as against the dimensions of the street and the spot you come from, the dimensions with which is is intended to impress you. Then you can feel the noble size of the mosque and your eyes can take its measure. You are in a great white marble space filled with light. Beyond you can see a second similar space of the same dimensions, but in half-light and raised on several steps (repetition in a minor key); on each side still a smaller space in subdued light; turning round, you have two very small spaces in shade.
From full light to shade, a rhythm. Tiny doors and enormous bays. You are captured, you have lost the sense of the common scale. You are enthralled by a sensorial rhythm (light and volume) and by an able use of scale and measure, into a world of its own which tells you what it set out to tell you.
