Well, you'll need a source for bigger clippings, and I personally would not put whole logs first, but rather bigger branches or bigger cuts / shredded material, then cover with smaller clippings.
I learned that this way: You excavate grass for 20-40 cm, then put in the bigger bits, then the smaller, and then compost, and the excavated grass bits on top, turned around so the roots are up and the green bits down, in fall. Ready to be planted in spring, when decomposition has started a bit. Called Hügelkultur btw., really funny for a native with the omitted Umlaut.
Sry.
Lasts for about three years, will then be rather flat.
