Sometimes porches may be estimated by the lineal foot, at from $2 to $4 per foot. This, however, is not the best method, its principal advantage being its simplicity and ease. The most common kind of porches, with which almost every one becomes familiar, may be estimated as above with generally satisfactory results. The best and most accurate way, however, is to estimate the framework, flooring, ceiling and roofing by the square; the cornice, gutters and latticework by the foot, and the steps, columns, brackets and ornamental work by the piece. After summing up the various parts the result may be taken as the most reliable estimate.
