Although the bigger projects might take more time to finish and will take more of your energy but it is the right method to do. The reason is because those projects will take more space in your yards thus you need to place them first before doing anything else.
Furthermore, usually those big projects will make your soil will become compact and might damage the plants and tuft around it. Thus, it is better to do the big projects first such as fencing, making patios, driveway, porch, and many others that you want to have on your yard. Do not forget that you might want to create a walkway that you can use to reach the backyard directly from your front yard. But you can always do it on the side where it is not too prominent.

But before you start to plant it, make sure to add organic matter to make it more fertile and readier for the plant to grow.
