What buildings do you consider necessary for convenient gardening and for relaxing in the backyard for the whole family?

If you like to spend evenings with your family in your backyard, then you need something like a patio or other place to relax. I know that recently small buildings are very popular. Vinyl pavilion kits, for example, aren't expensive, you can install it quickly and I know that such pavilions are usually good looking and easy to use. You can also use this for small parties. It seems to me that this is a good decision.
