Backyard but small area for chicken coop

[[E]thernet]

I am going to build a chicken coop, something with inspiration from this, and then place it in my backyard to keep my 3 chickens. My problem is, I have a decent size backyard, but most of it is used up.

I have attached a file that gives a very vague visualisation of my backyard. I have no idea where to put the coop. I want the coop to be small, but be comfortable for 3 chickens, as well as battle against the rain we have.

I can't take a photo rn as it is 1:08 AM and my parents are sleeping, so...

In 7 - 8 hours, I will post a photo.

Thank you for reading.
