I think a lot of people are dreaming too big (nothing wrong with that) and too conceptually (again, no fault, as dreams themselves are conceptual). The only issue, from my humble perspective, is that these dreams don’t have much detail. To get detail, we need to make a few basic assumptions to build on.

For the sake of detail, I’ll use my own yard as is, and take your question as ‘if money was no issue with where you currently live, what would you do to create your dream yard?’

My backyard is currently 10 m^2 ^ in size. At the back is a shrub bed along the fence. My front yard is about the same, but most of it consists of driveway, with two pretty narrow strips (maybe 3 m x 15 m) in size.

Backyard: the shrub-bed has coarse gravel in it, so I’d pull all that, along with the shrubs to be replanted later. I’d add 3-4 more layers of the landscaping bricks that act as the edge of the bed, and then backfill the newly created depth with mineral topsoil. I’d envision this whole thing being about 3 ft tall. I’d then replant the shrubs.

I remove the shed I have back there, and then create a similar dimension shrub bed, but with a shorter height wall, so the whole area is a two-step terrace. This layer would be about 50 cm deep, and backfilled with mineral topsoil, and planted with native bunch-grasses (looking at you fescues) and wildflowers such as wild bergamot.

I’ve got a shady spot along the south fence, so that would be bordered with a low-profile garden curb, filled with the coarse gravel, and planted with alder or dogwood to create a privacy screen. The north fence gets full sun exposure, so I’d want to do the same with the curb/gravel, but have some well-established spruce trees there, again for a screen. along the fences in the back, I’d put pollinator habitat/hotels.

Front yard: curb/coarse gravel, a few patches of lawn for visual effect, with most of the gravel bed filled in with bunch grasses/wildflowers.
