Here you can make such a beautiful oasis in the corner of your site. In the photo, of course, not the poorest cottage, but the idea itself is important. It is clear that the bench under the tree can be called a relaxation corner. And to build such a relaxation corner, yes, it is not easy.
Here, in my opinion, all the details are included. What do you need? A pond is a must, a place for sunbathing, greens, a flower bed for aesthetic enjoyment, a gazebo for eating and relaxing in the shade, a swing. Well, what else do you need? Although, maybe a small barbecue and a hammock. However, this is enough. It is unlikely that all these elements can fit in a small cottage, but the design of such a recreation area can be taken as a basis.
