We primarily work along the boundaries. This means: the terrace was roughly considered right from the building permit, the garage/carport as well. Once the house was built, the paved areas were finally fixed (path around the house and driveway), next the plants for the flowering hedge along the street and the (neighbor’s) garage driveways were chosen, and the middle was simply seeded with lawn. One boundary got a bee pasture.
The advantage is clearly that you have a rough framework and at least the boundaries are already designed AND you can leave the middle as it is for the time being.
Disadvantage: of course, you set certain basic conditions that might later not fit so well with the design of the middle. But this is quite deliberately planned to develop only in the next few years, when it becomes clearer where we need what, where beds or trees might be in the way, and how much time one actually wants to invest in the garden/ what effort the existing plants already require.
Unfortunately, it will surely take a while to get to a romantic, beautiful "real" garden this way; maybe it won’t come even in 20 years because something else always takes priority first. But plants and décor cost time and money—so I don’t regret our approach 99%.
