Tudor Revival’s decorative half-timber framing is meant to fool the eye—at least in the United States. What is it exactly? A frame of thin boards (often with stucco infilling) is added outside the cladding to mimic medieval construction techniques. Those long-ago structures depended upon heavy timbers to support the weight of the house. The space between those supporting timbers was filled, leaving them visible.
basement modern/medieval. this is what i would do. add a bit more medieval, like lightning like side "torches" and blacked chain hanging lanterns.... parallel thin wood/stained support beams with crown molding. Then floor would be stained wood, cork, marble like quartz, or different stone type of floor. maybe be stain glass windows.
