STREET ELEVATIONS.—In building a road of houses the expense would of course be considerable if to get variety a different plan and different details were employed for each house. Other methods must be adopted. In the case of twenty houses it would be well to get as many details, such as windows, doors, and door-frames, the same (or, at any rate, half of one kind and half of another), and monotony should be avoided by variation in the disposition of these features. An extensive elevation may also be made interesting by the treatment of a porch here, the addition of a bay window there, and the use of rough-cast somewhere else. An irregular building-line, where possible, is to be preferred. In a block of three cottages a pleasing effect is gained by projecting or recessing the middle one, or putting it with its long axis parallel with the road, and so forming a forecourt in front. SERVICE OF NATURAL ADVANTAGES.—Whatever natural advantages the land may possess, such as woods, pools, or streams (where they are not included in a park), should border, or be seen from, the road—that is if they merit the expense of road-making. Few things are more picturesque than a stream at the roadside (as at Tissington in Derbyshire), especially if spanned here and there by small bridges (as at Bourton-on-the-Water), and by their presence the road will be widened from house front to house front. The water of a stream should never be utilised for a manufacturing purpose where it afterwards flows through the village, except for generating electric power or other clean uses. If there is an avenue of old trees it should be secured for one of the roads. SHOPPING.—The chief shopping will be best placed just without and surrounding the main centre, and that of less importance round the minor centres. FACTORIES.—Supposing that the _raison d’être_ of the village or garden city be one or more industries in which many of the inhabitants are employed, where, it will be asked, are the factories to be placed? Without a definite example of land, it is difficult to give a definite reply. Many things are essential to such sites—for instance, the adjacency of a stream, river, or railway—and if the manufacturer transfers his works to the country, he will rightly choose the most convenient and advantageous site for them that offers, and other arrangements will have to be made in concert with him. Nevertheless, the factory or factories should be as far as possible from the main centre, that is on the village or city outskirts. The preferable position would lie between the north-east and south-west, for the prevalent south-west wind will then carry away the smoke in summer, when the villagers indulge in outdoor life, while the north and easterly winds of winter will carry it over the village when they are indoors. Screens of trees should be planted between the village and the factories as soon as possible.
