Hii, This is Torin Cole and I am a Teacher. My birth place is Bristol which is in the UK. Recently, I have gained the information about pergolas. In the bigger industry of pergola, “attached” stands for wall mounted, whereas “free standing” refers to anchor to the ground. An attached pergola structure is less expensive than free standing designs because an attached model has two support columns only. Furthermore, Pergola Kits with Roof is called a pavilion which is more costly due to the requirement of extra material and craftsmanship to build it.
