Yes and no. If you go with inexpensive wood (such as pine) and build it yourself, it can cost well under $1,000. However, if you build a large deck with expensive wood and hire an experienced and top-tier deck builder, it can cost well over $10,000.
Add on a pergola, fancy lighting, and an expensive fire pit and you'll spend a small fortune, but will have a terrific outdoor space. In a nutshell, the cost range is huge.
