Be aware that artificial turf can get very hot underfoot. You could lay a narrow old brick or limestone paver path to clothes line for easy access and plant ground covers or low profile herbs (eg.oregano and thyme) to use in cooking. Hardy herbs or flowers such as rosemary, lavender, geraniums against the edges of the space toward the back. Even add some large long troughs of flowers on the retaining wall to pretty up the area. It looks like it could get quite warm there but maybe a jasmine or similar climber to climb up a frame attached to the part of the large wall where there is no clothes line. Good luck, it will be a lovely space I'm sure once you get started.

sounds like a good use of space, you could install a pull out hotel clothes line, you know the one with the round fitting on one wall with a single pull out line which clips into a fitting on the other side. Attaching some photos the first is a bathroom that I would love to use to replace our existing ensuite (without replacing the window) which is as you enter the WC is behind the door to the left, right side is a nearly sunken bath with shower plus a large sliding window beside the bath, we think the architect hadn't allowed enough showering space so by adding the window gave extra width. Then we have a full width vanity and mirror on the third wall. The last should have a swimming pool style hand rail. Did you build your house, would love to see some more photos of the bathroom etc. cheers

Julie Herbert - thank you sooo much!!! I have seen these trees and wanted to know the names of them :) ...and now i know..I was googling fireworks trees hahaha. Thanks again!! I'm sooo happy now~

Your site is far too exposed for Maples. They are small trees that really need to be buffered from winds and too much sun by other plantings. They also need the soil constantly moist which will be nearly impossible on that slope. You really don't want to grow magnolias anywhere near the footings of a house. Have you seen how large a tree they are? Since you are in a temperate zone and like autumn foliage I can recommend a gingko tree. It will be right sized for your yard and give you that similar lighter than air look and autumn colour as maples but it's more hardy. Another option are silver birches. I would hedge the boundary for privacy and also to cut down winds to your garden which will dry out the grass and scorch it. With that slope you are going to need more rocks I think to prevent your topsoil from washing away in the first rain. It's really no use of us to provide you a list of random plants. What you need to do is put together a series of photo's of gardens you like the look of, then find plants to match that style. If you don't plan gardens then you end up with the ubiquitous suburban patch of grass and odd bushes look instead of a lovely garden.
