Decorem

I am currently working on making a design for a "Started Base" in my new LP world. (Not Finished) I really like the idea of the big layered decks but I cannot land on a wood for the main deck. Currently it is half oak half maple. The rest of the house is oak but I am not sold on the main deck also being oak. At the same time I cannot find anything that looks right. Ideally it is somewhat of an easy block to obtain. Any Ideas? I have also thrown the idea of replacing it with dirt and a retaining wall but I do want to keep the deck. Attached is the inspiration photo.
