An inviting entrance must also provide a sense of enclosure. A guest should feel as though they have entered the first room of the home. How often we see an entrance which is nothing more than a raised concrete slab providing little interest other than the token foundation planting countered with a wide expanse of lawn. Separating the arrival area with low seat walls, fences or railings accented with appropriate and attractive plantings will often provide a sense of security and a pleasant transition from public to private space. This is especially notable when dealing with a structure which fronts a busy street.
Straight lines are rigid, formal and undesirable.
Curves convey relaxation, comfort, and naturalness. To approach a front door on a walkway that looks like it was laid out at the conclusion of happy hour is not a relaxing experience. To plop down a wavering path for the sake of imitating nature should be avoided. You must consider the distance being traveled. If it is more than 30 feet from beginning to the entry landing, a curvilinear approach may be inviting.
