4' Tall Iron Fence
First of all, consider adding a fence to the border of a home. In front of the home, it could be a good idea to add a 4' tall iron fence. Fences made out of iron are classic and last very well outside. They sustain any type of weather, including the snow, rain, hail, sleet of the fall and winter months, and harsh sun of the spring and summer months. Consider adding a 4' tall iron fence to the front border of the front yard to help keep animals, kids, and other neighbors off from the lawn, as well.
This is a great idea, because it gives people a good idea of where your lawn starts and ends. It also helps home owners remember where to mow the lawn so that they don't end up mowing the neighbors' lawns. Remember, there are a ton of different options for fences in this height. There are fences that are very straight forward and simple, and there are more ornate versions that have designs in them. Pick one that matches the particular style and theme of the home that it will go in front of.
Another idea is to put iron fences that are a little smaller around gardens to keep little critters out and to help define the perimeter of the garden. These are very classy and look just as good as the taller fences. Check out fences in stores and online.
