As regards width, the walks should not be less than four feet six inches. The driveways should not be less than fourteen feet where it may be necessary to have vehicles pass, or ten feet where the entrance is within sight of the turn. Where a great expanse of ground makes it more consistent with a proportionate entrance to have greater width, the drives may be made sixteen or eighteen feet. This greater width is really necessary now to allow motor cars to pass one another comfortably.
Fig. 34. - The elliptical turn is attractive and practical either directly in front of the house or at the end. The ends should be full to give ample turning space. - See page 39.
Fig. 35. - To provide turning space for the largest motor cars it is necessary to have a circle not less than seventy feet in diameter. The center should be directly on the axis of the entrance door. - See page 39.
Where possible, the pedestrian walk should be combined with the drive, thus eliminating the further breaking up of the lawn. Walks and drives are necessary, but cannot be considered as pleasing landscape features where lawn space is small. Any scheme that will help to preserve the unbroken unity is to be desired.
Fig. 36. - The egg-shaped turn should always be placed at the end of the house and be well concealed by plantings. - See page 39.
Fig. 37. - A modified pear-shaped turn with the line nearest the house parallel to it. Such a turn is less desirable for the front of the house than one of formal design. - See page 39.
Fig. 38. - The rectangular turn is dignified and especially appropriate for Colonial houses. The center grass space may be enclosed with box edging to good effect. - See page 39.
Fig. 39. - When a drive or walk crosses a stream where a bridge is required it is advisable to cross at a right angle to the stream so that the wing walls may be built symmetrically. See page 39.
