Мечта дизайнеров, Большой открытый частный задний двор в стиле Волшебника страны Оз!

We have a very open backyard that is approximately 51' width x 63' length
The backyard currently is all green grass with large trees/bushes surrounding
Budget is in the 15k to 40k range, which we would do most of the work ourselves.
There is a Detached garage that also has an attached workshop.

There will be an additional reward if over 10 valid/qualified Submissions, and if over 15 qualified/valid Submissions another reward up to 1200.00 USD total.
We would like to receive many different ides to create a relaxing, quiet, serene, backyard

We would like our outdoor space to have a serene feel to it, to include a small water fall. We picture this space to be in the corner of the yard almost as if it were a separate space of it's own, possibly a small covered area such as a pergola, which has 1 to three swinging benches along with plants covering the top. I would also like it to include a fairytale theme such as the wizard of Oz, with a side flower garden, made of layered bricks, which are filled with poppies. I would also like to in corporate a yellow brick road, and a large tree with a face on it.
The focal point would be a fire pit made of cobble stone, pizza oven, built in bbq with fridge. Top bar should have open ice chest for drinks, surrounded by patio furniture, on a small deck with planter boxes.

We have a large window in our dinning room which over looks our entire back yard. When we stand at our window, we picture our back yard to have definition to it. We want an area for entertaining, and a small private area, all this surrounded by a Wizard of Oz theme with poppies, yellow brick road, and a woodsy tree.
It would be really cool to have the yellow brick road take you to the private area under the Pergola.
We will entertain the idea of lap pool, not too large, along with hot tub and water fall. But designs do not have to incorporate one.
We have considered opening the side of the workshop with french doors into a guest area/house.
We do need grass because of our pets , but not the entire backyard. Artificial turf?
This backyard is open to all ideas
