Retaining walls offer more value to a home if they also divert water, prevent erosion, or help support a foundation. The ROI of a retaining wall is between 100% and 200%.

Both fences and walls can increase your home’s value, but you’ll spend significantly more on a wall than you would on a fence. A stone wall costs approximately $5,000, a retaining wall costs $6,100, and a fence costs $3,200 on average to put prices in perspective. 

The thickness of a glass fence varies widely based on its application and whether or not there are any safety requirements, but most fences are between 8 millimeters and 12 millimeters thick. 12-millimeter-thick glass is extremely strong and overkill in most cases, which is why you typically only see it around pools and in skyscrapers.

All fences offer some degree of privacy, but standard perimeter fences may not be designed with that in mind. Dedicated privacy fences, however, tend to enclose smaller areas and feature more high-end materials that truly emphasize seclusion and comfort. Additionally, privacy fences typically offer fewer gaps to peek in through than standard fences, though you can likely adjust that to suit your preferences. 

The best wood for a farm fence is pressure-treated wood that will stand up to various weather conditions, animal contact, and moisture. Farm fences need to resist rot and damage, so choose a species such as cedar or redwood. The natural oils in these woods give them decay resistance, which also makes them ideal for other fence types, such as a wooden snow fence.
