WALL SPACES: ROUGH-CAST—WHITEWASH—HALF-TIMBER.—However strong may be the temptation to introduce a variety of colour upon exteriors, it is advisable with cottages of the class dealt with to refrain from so doing. It is best to get the colour in masses, treated broadly—say, each house, as far as wall surfaces and roof are concerned, of one colour; for where the cottages stand close together, or even where they are semi-detached, sufficient contrast or relief is afforded by contiguous cottages treated differently, and in the case of a village a much better general effect is thus gained. On the other hand a good effect may be gained by giving a block of houses one tone throughout, matching the colour of the roof. The result is quiet and unobtrusive, and one which is very desirable in the cottage, where the features are necessarily brought close together. The tarred plinth, however, should always be used with rough-cast. Half-timber should be used sparingly. While the bye-laws insist on a 9-in. wall being at the back, an unwarranted present and future expense is incurred by its use; and an effect equally as good, moreover, may be obtained with rough-cast, weather boarding, or whitewash. Half-timber one lives to regret, for the weather tells sadly upon it, and it demands constant repair. A small cottage with an equal distribution of equal-sized windows is far from desirable. In a pair of cottages where there are four equal rooms facing the road, four equal windows would at first sight seem unavoidable, although such an arrangement would be fatal to the elevation. It is better to put a secondary light to the rooms at the extremities, getting additional light from the side, and thus by contrast giving greater importance to the larger windows in the centre, or even to omit the smaller windows, if adequate light can be obtained without them. The blank space might then be used for the training up of climbing plants. A certain number of windows is indispensable in a cottage, but, without stinting light, the aim should rather be to repress any superfluity. By the means suggested the view from the interior is sometimes agreeably varied. Other features are dealt with in the descriptions of the various cottages to which they have particular reference.
