A large window with a white frame. A brown wooden chair. Plants on the floor. Doorways, and a mass of little windows opening into it. Here we have, as a matter of fact, but a very simple palette of the house, with its kitchen, bedroom, and lofted garden. This panorama, like the real estate agent’s booking, is made up of a series of images, the collection of which is, perhaps, the greatest barrier to a truly intelligent view of the building trades. They are themselves little glass-houses from which stream the rent for the dwelling occupiers. The whole arrangement is so made that the neighborhood seems to consist only of such glass houses.
