“From an ecological and natural point of view, privacy fences are the least desirable element in the landscape,” says Jonathan Fargion, a landscape designer based in New York City. This doesn’t mean privacy fences are necessarily a bad idea, just that there are a few considerations to take into account before getting started.
Privacy fences cut the land into lots, which can be problematic for the bugs, insects, and other wildlife that live there. “As a rule of thumb, fences should be at least two inches off the ground to let critters the freedom to move between properties,” Fargion explains. In general, he says privacy fences make the most sense on small properties, like town house gardens. For larger yards, he suggests making use of natural greenery, like trees, to keep unwanted eyes from infiltrating your space.
Fences that are six feet tall should block most views from the ground level. “I’d advise not going any taller than you have to, both to save on expenses and to limit the shrinking, enclosing effect fences can have on a space,” Lenhart says. If you do need extra height, he suggests adding 12 to 18 inches of lattice on the top of a fence, which will add privacy while minimizing the visual impact of a taller fence. If you opt for a natural privacy hedge, these can be much taller and often go up to 12 feet.
The best privacy fence will depend on each homeowner’s goals for the fence and their yard. “By necessity, privacy fences must obscure sight lines,” Lenhart says. For this reason, many privacy fences are made from solid wood and designed to be completely opaque. If the goal is to have complete seclusion, something solid without any gaps would likely be the best choice.
There are also fences that are a little more open and offer breathability in a space. “Obviously, a privacy fence fails if you can clearly see through it, but there’s a gradient with which designers can play,” Lenhart notes. In these instances, he says the goal is to include gaps that are large enough to be visible, but small enough to prevent a clear view. “The homeowner’s style and priorities will dictate the particular fence design to use on a given project,” Lenhart explains.
