In the ground plan, fig. 63. the entrances to the two houses are on opposite sides, on the same principle as in fig. 43. in p. 104; but here, the porches not being so conspicuous, and it being utterly impossible to see any considerable part of both at the same moment, from any point of view, the illusion is more complete. As this figure represents the ground plan of a double house and garden, one of which we designed, built, and laid out for ourselves, we shall, as a detailed illustration of the mode of laying out and planting suburban gardens of this kind, describe it at some length. The object was to build two small houses, which should appear as one, and have some pretensions to architectural design; being, at the same time, calculated for invalids, and, therefore, furnished with verandas extending nearly round the whole building, for taking exercise in during inclement weather. The houses form part of a row of detached dwellings lying parallel to Porchester Terrace, Bayswater, running north and south.

According to the principles we have laid down, the diagonal of the square ought to have been parallel to the road, instead of one of its sides; and we should have placed the building in this manner: but, on stating our intentions to the surveyor of the estate, from whom we took the ground on a ninety-nine years' lease, he objected to it, as it did not appear probable that it would be generally followed in the other buildings in the same row, and, therefore, was, in his opinion, likely to disfigure the terrace.
