Gwilt translation

11In these apartments, convenience must regulate the proportions. If the windows are not obscured by high walls adjoining, they may be easily contrived. But if any impediment occur, either through nearness of adjoining buildings or other obstruction, some ingenuity and skill will be requisite to diminish or increase their established proportions, so as to produce a pleasing effect not apparently different therefrom.

Morgan translation

11All the above-mentioned symmetrical relations should be observed, in these kinds of buildings, that can be observed without embarrassment caused by the situation. The windows will be an easy matter to arrange if they are not darkened by high walls; but in cases of confined space, or when there are other unavoidable obstructions, it will be permissible to make diminutions or additions in the symmetrical relations,—with ingenuity and acuteness, however, so that the result may be not unlike the beauty which is due to true symmetry.
