Need to add shade and entertainment area
Hello. I live in zone 4 in Colorado. Our backyard is blank canvas, or in reality, boring. The area that I am asking about is between the back of our house and the garage and is approx. 22' x 27'. This is the south side and is hot, especially this year. Our neighbors to the south recently cut down an ugly tree that did provide us with some shade. Our existing deck looks good but is too small. Rather than tear it down, I would rather add to it or put in a patio. The issue is getting shade on this south side. Our house is 100+ years old and has electrical wires coming to the house on this side, so any tree we might plant would have to be I would like to add an overhead structure like a pergola or arbor big enough to cover a significant portion of a new entertainment area - table and chairs. The current deck does get shaded from trees in the area to the west.
So my questions are:
Where to put an overhead structure, how to attach it, and what would it look like?
Should we extend the deck or ??? What type of plants would work here?
We are quite handy and would enjoy doing the work ourselves.
TIA for your suggestions.
