Hello I am looking to install a vinyl privacy fence on my front porch. The fence needs to be about 6ft tall & 8 about 7 or 8 feet wide. Then install door to access on the side (vinyl or anything cheap). Purpose: My front porch is highly visible & when checking the mail. This cause a bit of concern walking in my front lawn of checking my mail. So I want something to create privacy Just enough for me & my partner to check the mail & walk out of our home. Having a wooden fence of some kind is out of the question because I live in a neighborhood where building a fence will draw attention. The thing to figure out is building a solid foundation privacy without causing too much damage or drilling to our home. Can I get an estimate for this? I can also provide the materials needed. Thank you
