A fence is typically used to protect the house. It defines the outer boundary of a building and keeps unwanted visitors outside. Of course, fences don’t offer the same level of protection as compared to a proper wall, but that’s mainly because they aren’t designed to. Fences are ideally used in house construction to keep your pets in and to give you a protective view of the outdoors. The fence is placed around the garden and marks the boundary between your property and the street. However, many people are concerned about security when installing a fence.
